Re: NFSv4: mount -t nsf4 not the same as mount_newnfs?

Yea, I'd only use mount -t newnfs if for some reason you want to test/use the experimental client for nfsv2,3 instead of the regular one. I tried the above and it works. But it seems, that only UFS2 filesystems can be mounted by the client. When trying mounting a filesystem residing on ZFS, it fails. Mounting works, but when try to access or doing a simple 'ls', I get ls: /backup: Permission denied On server side, /etc/exports looks like -- V4: / -sec=sys:krb5 #IPv4# /backup #IPv4# -- Is there still an issue with ZFS? For ZFS, everything from the root specified by the V4: line must be exported at this time. So, if / isn't exported, the above won't work for ZFS. You can either export / or move the NFSv4 root down to backup. For example, you could try: V4:/backup -sec=sys:krb5 /backup (assuming /backup is the ZFS volume) and then a mount like: mount -t nfs -o nfsv4 server:/ /mnt will mount /backup on /mnt rick ps: ZFS also has its own export stuff, but it is my understanding that putting a line in /etc/exports is sufficient. I've never used ZFS, so others will know more than I. Well, I guess I havn't uderstood everything of NFSv4. The 'concept' of the 'root' is new to me, maybe there are some deeper explanation of the purpose? Are there supposed to be more than one 'root' enries or only one? At this very moment mounting seems to work, but I always get a 'permission denied' error on every ZFS exported filesystem. Doing the same with UFS2 filesystems, everything works as expected. Is there a way to inspect the exports and mounts for the used NFS-protocol? When issuing 'mount', the 'backup' mount is repoted to be 'newnfs', I assume this reflects NFSv4 being used, now I need to figure out what's going wrong with the ZFS export. NFS export of the ZFS filesystem is enabled, but as far as I know, this feature is not used in FreeBSD since ZFS in FreeBSD lacks of the capabilities of autonomously exporting its via NFS - well, I'm not an expert in this matter.

Re: hardware for home use large storage
CS pricey hardware raid cards for compatibility reasons. There seem to CS be no decent add-on SATA cards that play nice with FreeBSD other than CS that weird supermicro card that has to be physically hacked about to CS fit. BTW: I recently built some more machines with this card. I can confirm now that you can use it with standard brackets, if you have some spare. The distance for the two holders is the same as for e.g. 3ware 95/96 controllers and I had some spares in standard height there because I use the 3wares in low profile setups. The brackets of Intel NICs seem to fit, too. The only thing that is different with the card now is the side on which the components are mounted. But this should not be a problem unless you want to place them next ti a graphics card. cu Gerrit ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

Cheers, Mike In this thread with due respect to the OP the following might be considered a fruitless hack but it works!. Piping a processes output to dd(1) if you have a choice is a pretty fair temporary solution if a program does not offer that capability. For instance, I don't know if you are familiar with dump(8) at all, but I use a -P or pipe from that process to dd(8) to slow down the traffic that it tries to write over the network for backup purposes and then also give dump(8) a different nice level so it plays along. So even if you can cat your output and then read it in from fd(4) using dd(8) you still have a chance at slowing things down a little or writing at smaller increments that wont impact your environment as hard.

It takes up to 4GB of RAM, and there's even a version with KVM-over-LAN for headless operation and remote management. Neat hardware. But with regards to the KVM-over-LAN stuff: it's IPMI, and Supermicro has a very, *very* long history of having shoddy IPMI support. I've been told the latter by too many different individuals in the industry (some co-workers, some work at Yahoo, some at Rackable, etc.) for me to rely on it. If you *have* to go this route, make sure you get the IPMI module which has its own dedicated LAN port on the module and ***does not*** piggyback on top of an existing LAN port on the mainboard. What's wrong with the Supermicro IPMI implementations? I have several - all have a SEPARATE LAN port on the main board for the IPMI KVM (separate and distinct from the board's primary LAN ports), and I've not had any trouble with any of them. http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2008-01/msg01206.html http://forums.freebsd.org/showthread.php?t=7750 http://www.beowulf.org/archive/2007-November/019925.html http://bivald.com/lessons-learned/2009/06/supermicro_ipmi_problems_web_i.html http://lists.freebsd.org/pipermail/freebsd-stable/2008-August/044248.html http://lists.freebsd.org/pipermail/freebsd-stable/2008-August/044237.html (Last thread piece does mention that the user was able to get keyboard working by disabling umass(4) of all things) It gets worse when you use one of the IPMI modules that piggybacks on an existing Ethernet port -- the NIC driver for the OS, from the ground up, has to be fully aware of ASF and any quirks/oddities involved. For example, on bge(4) and bce(4), you'll find this (bge mentioned below): hw.bge.allow_asf Allow the ASF feature for cooperating with IPMI. Can cause sys- tem lockup problems on a small number of systems. Disabled by default. So unless the administrator intentionally sets the loader tunable prior to booting the OS installation, they'll find all kinds of MAC problems as a result of the IPMI piggybacking. Why isn't this enabled by default? I believe because there were reports of failures/problems on people's systems who *did not* have IPMI cards. Lose-lose situation. If you really want me to dig up people at Yahoo who have dealt with IPMI on thousands of Supermicro servers and the insanity involved (due to bugs, quirks, or implementation differences between the IPMI firmwares and which revision/model of module used), I can do so. Most of the complaints I've heard of stem from serial-over-IPMI. I don't think it'd be a very positive/supportive thread, however. :-) One similar product that does seem to work well is iLO, available on HP/Compaq hardware. I load these things over the IPKVM all the time. I leave a DVD-ROM in the drive when I install them and my initial load is done over the IPKVM on the board. It just works. Maybe they have had trouble in the past (most of those complaints look to be 2007/2008 issues), but the current stuff I use from them (their dual XEON boards) haven't given me a lick of trouble. And you can't argue with the price of the boards I use, considering that they have dual gigabit networking ports plus a separate IPMI LAN interface, support ECC memory and dual Xeons. I don't use the IPMI protocol itself but I **DO** use the remote console and management over HTTPS.

The management NIC freezes once a day (or more often) with older firmware and must be restarted from inside the installed system by IPMI command on localhost. With newer firmware, the interface is periodicaly restarded. The virtual media doesn't work at all. It is my worst experience with remote management cards. I believe that other HP servers with built-in card with different FW is working better, this is just my experience. Next one is eLOM in Sun Fire X2100 (shared NIC using bge + ASF). ASF works without problem, but virtual media works only if you are connecting by IP address, not by domain name (from Windows machines) and there is some issue with timeouts of virtual media / console. I reported this + 8 different bugs of web management interface to Sun more than year ago - none was fixed. Next place is for IBM 3650 + RSA II card (dedicated NIC). Expensive, something works, somthing not. For example the card can't read CPU temperature, so you will not recieve any alert in case of overheating. (it was 2 years ago, maybe newer firmware is fixed) Then I have one Supermicro Twin server 6016TT-TF with built-in IPMI / KVM with dedicated NIC port. I found one bug with fan rpm readings (half the number compared to BIOS numbers) and one problem with FreeBSD 7.x sysinstall (USB keyboard not working, but sysinstall from 8.x works without problem). In installed FreeBSD system keyboard and virtual media is working without problems.

I have addon card in ML110 G5 (dedicated NIC), the card is expensive and bugs are amazing. The management NIC freezes once a day (or more often) with older firmware and must be restarted from inside the installed system by IPMI command on localhost. With newer firmware, the interface is periodicaly restarded. The virtual media doesn't work at all. It is my worst experience with remote management cards. I believe that other HP servers with built-in card with different FW is working better, this is just my experience. Next one is eLOM in Sun Fire X2100 (shared NIC using bge + ASF). ASF works without problem, but virtual media works only if you are connecting by IP address, not by domain name (from Windows machines) and there is some issue with timeouts of virtual media / console. I reported this + 8 different bugs of web management interface to Sun more than year ago - none was fixed. Next place is for IBM 3650 + RSA II card (dedicated NIC). Expensive, something works, somthing not. For example the card can't read CPU temperature, so you will not recieve any alert in case of overheating. (it was 2 years ago, maybe newer firmware is fixed) Then I have one Supermicro Twin server 6016TT-TF with built-in IPMI / KVM with dedicated NIC port. I found one bug with fan rpm readings (half the number compared to BIOS numbers) and one problem with FreeBSD 7.x sysinstall (USB keyboard not working, but sysinstall from 8.x works without problem). In installed FreeBSD system keyboard and virtual media is working without problems. On the top is Dell R610 DRAC (dedicated NIC) - I didn't find any bugs and there are a lot more features compared to concurrent products. I think the general consensus here is nice theory lousy implementation, and the added migraine of no such thing as a common standard. Maybe creating a common standard for this could be a nice GSOC project, to build a nice remote console based on SSH and arm/mips? p.s. I've seen the various proprietary remote console solutions. They didn't really impress me much, so I ended up using off-the-shelf components for building my servers.

Are there supposed to be more than one 'root' enries or only one? Only to specify different security flavours for different client host IP#s. There is only one root location in the file system tree. This was done for NFSv4 to avoid any need for the mount protocol. See below. At this very moment mounting seems to work, but I always get a 'permission denied' error on every ZFS exported filesystem. Doing the same with UFS2 filesystems, everything works as expected. In NFSv4 mount does very little, since it does not use the mount protocol. It basically passes a pathname from the NFSv4 root into the kernel for later use. (Since UFS doesn't actually check exports, the experimental server checks them, but cheats and allows a minimal set of NFSv4 Operations on non-exported volumes, so that this pathname can be traversed to the exported volume. At this time ZFS checks exports. As such everything in the tree from the root specified by the V4: line must be exported for ZFS to work. I believe others have gotten a ZFS export to work, but I have no experience with it at this time. Is there a way to inspect the exports and mounts for the used NFS-protocol? Not that I am aware. (Excluding ZFS, which I don't know anything about, the /etc/exports file specifies the exports.) When issuing 'mount', the 'backup' mount is repoted to be 'newnfs', I assume this reflects NFSv4 being used, now I need to figure out what's going wrong with the ZFS export. NFS export of the ZFS filesystem is enabled, but as far as I know, this feature is not used in FreeBSD since ZFS in FreeBSD lacks of the capabilities of autonomously exporting its via NFS - well, I'm not an expert in this matter. I'm definitely not a ZFS expert either:-) I think the mount command is showing you that the mount point was created (newnfs refers to the experimental client), but as noted above, that doesn't indicate that it is accessible. (If you haven't tried moving the V4: /backup ... that moves the NFSv4 root to /backup, you should do that and see how it goes.)

That's faster than just about anything I have at home. So you should be fine. It should be good enough to serve as primary media center storage even (for retrievals, anyway, probably a tad bit slow for live transcoding).

Re: zpool vdev vs. glabel
On Tue, Feb 9, 2010 at 6:26 AM, Jeremy Chadwick free...@jdc.parodius.comwrote: Also, I'm a little confused as to the use of glabel in this case. In what condition do your disk indices (e.g. X of daX) change? Are you yanking multiple disks out of a system at the same time and then shoving them back into different drive bays? Are you switching between storage subsystem drivers (ahci(4) vs. ataahci(4), for example) regularly? I've yet to be convinced glabel is worth bothering with, unless the system adheres to one of the above situations (which are worthy of strangulation anyway ;-) ). Use multiple disk controllers in a server, and watch as kernel updates and/or BIOS updates change the order that the controllers are probed, thus changing the dev node for every disk in the system. Use multiple disk controllers that use CAM, then move from an IDE-based CompactFlash adapter to a SATA-based CompactFlash adapter for the / filesystem, and watch the system renumber all your dev nodes. Use a RAID controller configured for JBOD or Single Disk arrays, and replace a drive while the server is running, which assigns the disk largest da number +1, then renumbers everything when the server reboots. After you run into those kinds of things a few times, you'll start to use glabel(8) for everything. Plus, it just makes things easier to understand. Instead of da0 through da25 which is a mix of SATA, RAID, and USB drives, you have cfdisk0, cfdisk1, disk00 through disk24, and so on. Personally, the greatest thing to ever happen to FreeBSD is the introduction of GEOM, and the addition of the glabel class. :) While ZFS does it's own disk labelling behind the scenes, using glabel just makes things easier. -- Freddie Cash fjwc...@gmail.com ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

They use software RAID and hardware RAID at the same time? I'm not sure what you mean by this. Compatibility with FreeBSD? Add-on (PCI-X/PCIe) RAID controllers tend to have solid drivers in FreeBSD. Add-on SATA controllers not so much. The RAID controllers also tend to support more SATA features like NCQ, hot-swap, monitoring, etc. They also enable you to use the same hardware across OSes (FreeBSD, Linux, etc). For example, we use 3Ware controllers in all our servers, as they have good, solid support under FreeBSD and Linux. On the Linux servers, we use hardware RAID. On the FreeBSD servers, we use them as SATA controllers (Single Disk arrays, not JBOD). Either way, the management is the same, the drivers are the same, the support is the same. It's hard to find good, non-RAID, SATA controllers with solid FreeBSD support, and good throughput, with any kind of management/monitoring features. And I thought I found one in the Adaptec 1405 Integrated SAS/SATA controller, because it's marketed as an inexpensive SAS/SATA non-RAID addon-card. On top of that, they advertise it as having FreeBSD6 and FreeBSD7-support and drivers. So I ordered it for my storage-box (FreeNAS) with great expectations. Sadly, they don't have support nor drivers for FreeBSD (drivers will be released Q4 2009) at all, so I'm thinking of leaving FreeNAS and trying some linux-flavor that does support this card... But Adaptec doesn't have a great track-record for FreeBSD-support, does it? Everything is a repackage of some OEM these days (basically gone are the days of Adaptec==LSI==mpt(4) and all). Find the actual chipset make and model if you can, then you can look at what is supported, as the drivers deal with the actual chipset and could care less about the brand of some vertically-integrated fpga package.

Re: hardware for home use large storage
The Silicon Image 3124A chipsets (the PCI-e version of the 3124. The original 3124 was PCI-x). The 3124A's are starting to make their way into distribution channels. This is probably the best 'cheap' solution which offers fully concurrent multi-target NCQ operation through a port multiplier enclosure with more than the PCIe 1x bus the ultra-cheap 3132 offers. I think the 3124A uses an 8x bus (not quite sure, but it is more than 1x). AHCI on-motherboard with equivalent capabilities do not appear to be in wide distribution yet. Most AHCI chips can do NCQ to a single target (even a single target behind a PM), but not concurrently to multiple targets behind a port multiplier. Even though SATA bandwidth constraints might seem to make this a reasonable alternative it actually isn't because any seek heavy activity to multiple drives will be serialized and perform EXTREMELY poorly. Linear performance will be fine. Random performance will be horrible. It should be noted that while hotswap is supported with silicon image chipsets and port multiplier enclosures (which also use Sili chips in the enclosure), the hot-swap capability is not anywhere near as robust as you would find with a more costly commercial SAS setup. SI chips are very poorly made (this is the same company that went bust under another name a few years back due to shoddy chipsets), and have a lot of on-chip hardware bugs, but fortunately OSS driver writers (linux guys) have been able to work around most of them. So even though the chipset is a bit shoddy actual operation is quite good. However, this does mean you generally want to idle all activity on the enclosure to safely hot swap anything, not just the drive you are pulling out. I've done a lot of testing and hot-swapping an idle disk while other drives in the same enclosure are hot is not reliable (for a cheap port multiplier enclosure using a Sili chip inside, which nearly all do). Also, a disk failure within the enclosure can create major command sequencing issues for other targets in the enclosure because error processing has to be serialized. Fine for home use but don't expect miracles if you have a drive failure. The Sili chips and port multiplier enclosures are definitely the cheapest multi-disk solution. You lose on aggregate bandwidth and you lose on some robustness but you get the hot-swap basically for free. -- Multi-HD setups for home use are usually a lose. I've found over the years that it is better to just buy a big whopping drive and then another one or two for backups and not try to gang them together in a RAID. And yes, at one time in the past I was running three separate RAID-5 using 3ware controllers. I don't anymore and I'm a lot happier. If you have more than 2TB worth of critical data you don't have much of a choice, but I'd go with as few physical drives as possible regardless. The 2TB Maxtor green or black drives are nice. I strongly recommend getting the highest-capacity drives you can afford if you don't want your power bill to blow out your budget. The bigger problem is always having an independent backup of the data. Depending on a single-instanced filesystem, even one like ZFS, for a lifetime's worth of data is not a good idea. Fire, theft... there are a lot of ways the data can be lost. So when designing the main system you have to take care to also design the backup regimen including something off-site (or swapping the physical drive once a month, etc). i.e. multiple backup regimens. If single-drive throughput is an issue then using ZFS's caching solution with a small SSD is the way to go (and yes, DFly has a SSD caching solution now too but that's not pertainant to this thread). The Intel SSDs are really nice, but I am singularly unimpressed with the OCZ Colossus's which don't even negotiate NCQ. I don't know much re: other vendors. A little $100 Intel 40G SSD has around a 40TB write endurance and can last 10 years as a disk meta-data caching environment with a little care, particularly if you only cache meta-data. A very small incremental cost gives you 120-200MB/sec of seek-agnostic bandwidth which is perfect for network serving, backup, remote filesystems, etc. Unless the box has 10GigE or multiple 1xGigE network links there's no real need to try to push HD throughput beyond what the network can do so it really comes down to avoiding thrashing the HDs with random seeks. That is what the small SSD cache gives you. It can be like night and day. -Matt ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To

In what condition do your disk indices (e.g. X of daX) change? Are you yanking multiple disks out of a system at the same time and then shoving them back into different drive bays? Are you switching between storage subsystem drivers (ahci(4) vs. ataahci(4), for example) regularly? I've yet to be convinced glabel is worth bothering with, unless the system adheres to one of the above situations (which are worthy of strangulation anyway ;-) ). Use multiple disk controllers in a server, and watch as kernel updates and/or BIOS updates change the order that the controllers are probed, thus changing the dev node for every disk in the system. Use multiple disk controllers that use CAM, then move from an IDE-based CompactFlash adapter to a SATA-based CompactFlash adapter for the / filesystem, and watch the system renumber all your dev nodes. Use a RAID controller configured for JBOD or Single Disk arrays, and replace a drive while the server is running, which assigns the disk largest da number +1, then renumbers everything when the server reboots. After you run into those kinds of things a few times, you'll start to use glabel(8) for everything. Plus, it just makes things easier to understand. Instead of da0 through da25 which is a mix of SATA, RAID, and USB drives, you have cfdisk0, cfdisk1, disk00 through disk24, and so on. Personally, the greatest thing to ever happen to FreeBSD is the introduction of GEOM, and the addition of the glabel class. :) Yeah. GEOM is very very very nice. It is a very elegant solution to a lot of problems. I always wonder why other OS'es didn't pick it up. Ronald. While ZFS does it's own disk labelling behind the scenes, using glabel just makes things easier. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

It takes up to 4GB of RAM, and there's even a version with KVM-over-LAN for headless operation and remote management. Neat hardware. But with regards to the KVM-over-LAN stuff: it's IPMI, and Supermicro has a very, *very* long history of having shoddy IPMI support. I've been told the latter by too many different individuals in the industry (some co-workers, some work at Yahoo, some at Rackable, etc.) for me to rely on it. If you *have* to go this route, make sure you get the IPMI module which has its own dedicated LAN port on the module and ***does not*** piggyback on top of an existing LAN port on the mainboard. What's wrong with the Supermicro IPMI implementations? I have several - all have a SEPARATE LAN port on the main board for the IPMI KVM (separate and distinct from the board's primary LAN ports), and I've not had any trouble with any of them. http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2008-01/msg01206.html http://forums.freebsd.org/showthread.php?t=7750 http://www.beowulf.org/archive/2007-November/019925.html http://bivald.com/lessons-learned/2009/06/supermicro_ipmi_problems_web_i.html http://lists.freebsd.org/pipermail/freebsd-stable/2008-August/044248.html http://lists.freebsd.org/pipermail/freebsd-stable/2008-August/044237.html (Last thread piece does mention that the user was able to get keyboard working by disabling umass(4) of all things) I have a box down at Softlayer (one of the few major server rental outfits that officially supports FreeBSD), and one of the reasons I went with them is that they advertised IP-KVM support. Turns out they run Supermicro boxes with the IPMI card. It mostly works, but it is very quirky and you have to use a very wonky Java client app to get the remote console. You have to build a kernel that omits certain USB devices to make the keyboard work over the KVM connection (and their stock FBSD install has it disabled). I can usually get in, but sometimes I have to open a ticket with them and a tech does some kind of reset on the card. I don't know if they a hitting a button on the card/chassis or if they have some way to do this remotely. After they do that, I'll see something like this in dmesg: umass0: Peppercon AG Multidevice, class 0/0, rev 2.00/0.01, addr 2 on uhub4 ums0: Peppercon AG Multidevice, class 0/0, rev 2.00/0.01, addr 2 on uhub4 ums0: 3 buttons and Z dir. ukbd0: Peppercon AG Multidevice, class 0/0, rev 2.00/0.01, addr 2 on uhub4 kbd2 at ukbd0 The umass device is to support the virtual media feature that simply does not work. It's supposed to allow you to point the ipmi card at an iso or disk image on an SMB server and boot your server off of it. I had no luck with this. All the IPMI power on/off, reset, and hw monitoring functions do work well though. It gets worse when you use one of the IPMI modules that piggybacks on an existing Ethernet port -- the NIC driver for the OS, from the ground up, has to be fully aware of ASF and any quirks/oddities involved. For example, on bge(4) and bce(4), you'll find this (bge mentioned below): hw.bge.allow_asf Allow the ASF feature for cooperating with IPMI. Can cause sys- tem lockup problems on a small number of systems. Disabled by default. So unless the administrator intentionally sets the loader tunable prior to booting the OS installation, they'll find all kinds of MAC problems as a result of the IPMI piggybacking. Why isn't this enabled by default? I believe because there were reports of failures/problems on people's systems who *did not* have IPMI cards. Lose-lose situation. I don't think they have this setup, or if they do, they are using it on the internal LAN, so I don't notice any weirdness. If you really want me to dig up people at Yahoo who have dealt with IPMI on thousands of Supermicro servers and the insanity involved (due to bugs, quirks, or implementation differences between the IPMI firmwares and which revision/model of module used), I can do so. Most of the complaints I've heard of stem from serial-over-IPMI. I don't think it'd be a very positive/supportive thread, however. :-) One similar product that does seem to work well is iLO, available on HP/Compaq hardware. I've heard great things about that.

HD4770 cards work with explicit set option DRI OFF As far as I know, WITHOUT_NOUVEAU does have no effect on the current ports, since it is reported in ports/UPDATING, it prevents building nouveau driver which is broken when using newer libdrm/dri and libGLUT, but those new ports do not seem to be merged into the tree.

Re: Unresponsive keyboard after a few boots
Yes, this is a USB keyboard. If I plug in an external USB keyboard I get the same behaviour. In the mean time, I have discovered that if I boot the machine with MacOSX and then reboot into FreeBSD, it is very likely that FreeBSD will have no problems with using the keyboard. I am sure that this behaviour is new in 8.0/stable. Now that I have this method, I am willing to dig deeper into this problem and collect more information for debugging. Any ideas on how to proceed? regards, On Wed, Feb 10, 2010 at 1:16 AM, Chris Rees utis...@googlemail.com wrote: On 8 February 2010 11:47, Jeremy Chadwick free...@jdc.parodius.com wrote: On Mon, Feb 08, 2010 at 02:19:06PM +0530, Rohit Grover wrote: I am using a very recent Freebsd 8.0 STABLE on a Macbook.

To be fair - my ATI X300 has always worked. It is a cheap card with low-end performance but it is perfectly fine for regular desktop-use. The older chipsets are better supported because the newer ones are, well, newer. If you haven't bought a video card yet, look at the radeon(4x) man page first. Unfortunately, that doesn't help if you already have a newer card, or a notebook. The other choices are Intel, where they don't have standalone video cards, or nVidia, which has a full-featured blob and a really bare-bones open driver. -Warren Block * Rapid City, South Dakota USA ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
Re: FreeBSD 8.0 i386 unable to boot...
About this problem, I have seen that in the past there have been problem with libdisk when a WinXP partition had an invalid name. Could it be something like that that could be causing this error? I guess the problem occurs somewhere in the Open_Disk function of libdisk, right? Should I be able to get around this problem by installing through a PC-BSD CD instead? I have never tried PC-BSD. Does their installer rely on libdisk at all? Thanks!

There seem to be no decent add-on SATA cards that play nice with FreeBSD other than that weird supermicro card that has to be physically hacked about to fit. Mostly only because certain cards have issues w/shoddy JBOD implementation. Some cards (most notably ones like Adaptec 2610A which was rebranded by Dell as the CERC SATA 1.5/6ch back in the day) won't let you run the drives in passthrough mode and seem to all want to stick their grubby little RAID paws into your JBOD setup (i.e. the only way to have minimal participation from the hardware RAID is to set each disk as its own RAID-0/volume in the controller BIOS) which then cascades into issues with SMART, AHCI, triple caching/write reordering, etc on the FreeBSD side (the controller's own craptastic cache, ZFS vdev cache, vmm/app cache, oh my!). So *some* people go with something tried-and-true (basically bordering on server-level cards that let you ditch any BIOS type of RAID config and present the raw disk devices to the kernel) As someone else has mentioned, recent SiL stuff works well. I have multiple http://www.newegg.com/Product/Product.aspx?Item=N82E16816132008 cards servicing RAID-Z2 and GEOM_RAID3 arrays on 8.0-RELEASE and 8.0-STABLE machines using both the old ata(4) driver and ATA_CAM. Don't let the RAID label scare you--that stuff is off by default and the controller just presents the disks to the operating system. Hot swap works. I haven't had the time to try the siis(4) driver for them, which would result in better performance. That's a really good price. :) If needed, I could host all eight SATA drives for $160, much cheaper than any of the other RAID cards I've seen. The issue then is finding a motherboard which has 4x PCI Express slots. ;) ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
Re: hardware for home use large storage
Trying to make sense of stuff I don't know about... Matthew Dillon wrote: AHCI on-motherboard with equivalent capabilities do not appear to be in wide distribution yet. Most AHCI chips can do NCQ to a single target (even a single target behind a PM), but not concurrently to multiple targets behind a port multiplier. Even though SATA bandwidth constraints might seem to make this a reasonable alternative it actually isn't because any seek heavy activity to multiple drives will be serialized and perform EXTREMELY poorly. Linear performance will be fine. Random performance will be horrible. Don't use a port multiplier and this goes away. I was hoping to avoid a PM and using something like the Syba PCI Express SATA II 4 x Ports RAID Controller seems to be the best solution so far. http://www.amazon.com/Syba-Express-Ports-Controller-SY-PEX40008/dp/B002R0DZWQ/ref=sr_1_22?ie=UTF8s=electronicsqid=1258452902sr=1-22 It should be noted that while hotswap is supported with silicon image chipsets and port multiplier enclosures (which also use Sili chips in the enclosure), the hot-swap capability is not anywhere near as robust as you would find with a more costly commercial SAS setup. SI chips are very poorly made (this is the same company that went bust under another name a few years back due to shoddy chipsets), and have a lot of on-chip hardware bugs, but fortunately OSS driver writers (linux guys) have been able to work around most of them. So even though the chipset is a bit shoddy actual operation is quite good. However, this does mean you generally want to idle all activity on the enclosure to safely hot swap anything, not just the drive you are pulling out. I've done a lot of testing and hot-swapping an idle disk while other drives in the same enclosure are hot is not reliable (for a cheap port multiplier enclosure using a Sili chip inside, which nearly all do). What I'm planning to use is an SATA enclosure but I'm pretty sure a port multiplier is not involved: http://www.athenapower.us/web_backplane_zoom/bp_sata3141b.html Also, a disk failure within the enclosure can create major command sequencing issues for other targets in the enclosure because error processing has to be serialized. Fine for home use but don't expect miracles if you have a drive failure. Another reason to avoid port multipliers. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

This idea is a pure guess , but when FreeBSD 8.0 starts initially and USB key board does not work , there seems that this is most likely possibility . If it is possible the following steps may be useful : Initially start MacOSX , dump all of the related circuit register values . Start FreeBSD 8.0 , repeat the dumping of the related circuit register values . This will give differences between two boots . Initially start FreeBSD and dump all of the related circuit register values . This may require a key board . Problem is to override this requirement . If in the system there is also a PS/2 key board slot , a PS/2 keyboard may be utilized . Another way may be a shell script or program starting on boot automatically to dump the required values . In that case , a key board may not be required . This will show uninitialized values . Related sources may also be studied to understand which areas are left without initializations . Successive boots may clear properly stored circuit register values and they do not initialize them properly . Thank you very much .
