Re: [zfs-discuss] can anyone help me?
Hi Hernan, after looking at your posts my suggestion would be to try the OpenSolaris 2008.05 Live CD and to import your pool using the CD. That CD is nv86 + some extra fixes. You will have to use 'pfexec' when you are trying to import the pool. ( www.opensolaris.com ) I read this and I am not sure how you did it. S10U4 and was recently upgraded to snv85 But an upgrade from Sol10 to NV is untested and nothing I would recommend at all. A fresh install of snvXY is what I know works.

Re: [zfs-discuss] SMC Webconsole 3.1 and ZFS Administration 1.0 - stacktraces in snv_b89
A further update. With B90 and UFS as root partition, the ZFS administration GUI worked fine. So I presented two additional disks and proceeded to create a zpool. The creation of the pool worked fine however the ZFS administration interface is now broken with the same error as in the original post. So to summarise, ZFS GUI adminstration seems to be broken once a ZFS pool exists on the system with at least B90. Is this a bug or is there a workaround?

Re: [zfs-discuss] SMC Webconsole 3.1 and ZFS Administration 1.0 - stacktraces in snv_b89
I checked - this system has a UFS root. When installed as snv_84 and then LU'd to snv_89, and when I fiddled with these packages from various other releases, it had the stacktrace instead of the ZFS admin GUI (or the well-known smcwebserver restart effect for the older packages). . Were your UFS and ZFS setups different in packaging? No. These were straight vanilla installs of SXCE B90 with Entire Distrubtion. With my original post I thought it might of been related to ZFS as the root partition but with further testing that is not the case at all...

You should consider using SMB or NFS and storing the files in native ZFS filesystem format. I think that this would work better for ZFS snapshots than the single large file used by iSCSI. The files could be shared by more than one host, including being visible to your server for administrative purposes. ZFS snapshots of iSCSI disks are not assured to be coherent from the perspective of the remote host which uses it and will be more similar to what you get when you abruply unplug the power from your remote host unless you take care to shut down the remote host prior to snapshotting. Certainly Apple's journalling will help here, but journalling works by losing some data.

Use froogle for price checking. I don't know what chipsets are supported by opensolaris, but if I were you I'd be looking hard at motherboards with as much integrated as possible. For instance, for less than $100 you can get a mini-atx motherboard with 6 SATA ports and onboard video. I found this out just by clicking the appropriate categories on the left side of newegg. Example: http://www.newegg.com/Product/ProductList.aspx?Submit=ENEN=2010200022+107192530name=NVIDIA+GeForce+8000 Pair a motherboard like that with the cheapest processor possible, a case that comes with a power supply, and a hard drive bay for the 5.25 case bays, and you're off like a bride's pajamas! I'd get wd6400aaks or wd7500aacs drives. the aacs (GP) drives are 5400rpm and vibrate less, which will cause less noise problems in most cases, if you know what I mean. As a bonus, some of the consumer AMD chipsets are compatible with unbuffered ECC memory, so you can use this http://www.newegg.com/Product/Product.aspx?Item=N82E16820146525 . The memory you chose is not what you need. DDR2 667mhz * 2 is 1333mhz, which is a faster bus speed than the processor you chose. So you won't even use all the speed of 667 memory, not to mention the 800 memory you chose.

Re: [zfs-discuss] What is a vdev?
As a side bar, since you cannot remove a vdev, you can really shot oneself in the foot if not careful (as I recently did). I had a X4500 system with (4) RAIDz2 vdevs in one pool. When adding a disk to the system, I forgot to add it as a spare and I was left with a stripe across the RAIDz2 sets + a single disk. I had to blow everything away... Any information on when disk evacuation will make its way into ZFS? Robert On May 25, 2008, at 3:11 PM, Kyle McDonald wrote: Orvar Korvar wrote: Ok, so i make one vdev out of 8 discs. And I combine all vdevs into one large zpool? Is it correct? I have 8 port SATA card. I have 4 drives into one zpool. That is one vdev, right? Now I can add 4 new drives and make them into one zpool. And now I combine both zpool into one zpool? That can not be right? I dont get vdevs. Can someone explain? A 'vdev' is the basic unit that a zpool is made of. There are several types of vdevs: Single device type: This vdev is made from one storage device - Generally a Hard disk drive, but there are other possibilities. This type of vdev has *no* data redundancy, but ZFS will still be able to notice errors due to checksumming every block. ZFS will also keep redundant meta-data on this one device, so meta data has the ability to survive block failures, but nothing will save data in this type of vdev from a full device failure. The size of this vdev is the size of the storage device it is made from. Mirrored type: This type of vdev is made from 2 or more storage devices, All data is written to all devices, so there is data redundancy. The more devices in the mirror the more copies of the data, and the more full device failures the vdev can survive. The size of this vdev is the size of the smallest storage device in the mirror. While devices (copies) can be added and removed from the mirror vdev, this only changes the redundancy, and not the size. Though if the smallest storage device in the mirror is replaced with a larger one, the size of the mirror should grow to the size of the new smallest device in the mirror. RAIDZ or RAIDZ1 type: This type of vdev is made of 3 or more storage devices. This type of vdev has data redundancy, and can survive the loss of one device in the vdev at a time. The available space on a RAIDZ vdev is the size of the smallest storage device in the vdev times one less than the number of devices in the vdev ( minsize*(n-1) ) because 1 devices worth of space is used for parity information to provide the redundancy. This vdev type cannot (currently) have it's size changes by adding or removing (changing 'n') devices to/from it. However it can have it's available space increased by replacing the current smallest device with a larger device (changing 'minsize') so that some other device now becomes the 'smallest device'. NOTE: if the vdev started with identical sized devices, you'll need to replace all of them before you'll see any increase in the available space since the 'size of the smallest device' will still be the same untill they are all replaced. Posts by knowledgable people on this mailing list have suggested that there is little benefit to having 10 or more devices in a RAIDZ vdev., and that devices should be split into multiple vdevs to keep the number in anyone in the single digits. RAIDZ2 type: This type of vdev is made of 4 or more storage devices. It is basically just like RAIDZ1, except it has enoug redundancy to survive 2 device failures at the same time, and the available space is the size of the smallest device times *two* less than number of devices in the vdev ( minsize*(n-2) ) becuase 2 devices worth of space are used to provide the redundancy. Changing the space in this type of vdev is limited the same way that a RAIDZ vdev is. As noted above, the term 'Storage Device' in these descriptoins is generally a hard disk drive, but it can be other things. ZFS allows you to use files on another filesystem, slices (solaris partitions) of a drive, fdisk partitions, Hardware RAID LUNs, iSCSI targets, USB thumb drives, etc. A Zpool is made up of more than one of these vdev's. The size of a zpool is the sum of the sizes of the vdevs it is made from. The zpool doesn't add any redundancy itself, the vdev's are responsible for that. Which is why, while a zpool can be made of vdev's of differing types, it's not a good idea. The 'zpool create' command will warn you if you try to use a mix of redundant and non-redundant vdev types in the same pool. This is really a bad idea since you can't control what data is placed on the redundant vdev's and which is places on the non- redundant vdev's. If you have data that has different redundancy needs, you're better off creating more than one zpool. Vdev's can be added to a zpool, but not removed (yet?) Therefore to increase the size of a of zpool, you have to either add another full vdev to it, or replace one (or

You would need to push the Amanda people to support star if you like to backup a filesystem other than UFS. Currently Amanda will use GNU tar with all well known problems with GNU tar based backups (e.g. GNU tar will not always accept it's own archives for restore).

Re: [zfs-discuss] /var/sadm on zfs?
On my heavily-patched Solaris 10U4 system, the size of /var (on UFS) has gotten way out of hand due to the remarkably large growth of /var/sadm. Can this directory tree be safely moved to a zfs filesystem? How much of /var can be moved to a zfs filesystem without causing boot or runtime issues? It seems your original question hasn't been answered yet... :-) I have used U4 with the complete /var on zfs for quite a while and have not encountered any problems. My usual setup for mirrored root disks is: what where how / /dev/md/dsk/d0 ufs swap /dev/md/dsk/d1 swap ROOT cXt0d0s3 + cXt1d0s3zpool The ROOT pool contains /var, /opt, and /export. I set both quota and reservation for /var to be on the safe side. I have not done any stress testing with zones, but normal use is absolutely trouble-free. HTH -- Volker -- Volker A.

Re: [zfs-discuss] ZFS sharing options for Windows
Justin, Thanks for the reply In the environment I currently work in, the powers that be are almost completely anti unix. Installing the nfs client on all machines would take a real good sales pitch. None the less I am still I've pro unix I'm against putting NFS on all the PC clients as well. Putting Samba on the server and leaving the PCs alone will be much easier to manage then NFS clients. I suspect the performance and security on the PCs would be better too. Samba can authenticate to AD or have it own seperate passowrd setup. If it's a Windows shop, use AD. I've not played with the CIFS in ZFS yet, but I have older Solaris installs and Samba works well enough that I don't have a need to switch yet. playing with the client in our sandbox. As I install this on a test machine a question popped into my mind. Does this passthrough AD credentials? How does one control authentication? I haven't read anything on this yet, and will do some searching, just thought I'd pick your brain a bit. Samba does. I think CIFS in ZFS would be done with PAM? The biggest reason I am drawn to ZFS is zpool. I like the idea I can keep adding raidz arrays to a large shared pool when ever I want. With iscsi sharing I am forced to make Volumes I don't know that I really like this idea outside of the scope of making iSCSI OS partitions. For network files and shares I really want to be able utilize snapshots and other features of the ZFS filesystem. If I share out via SMB do the files not sit on the zfs FS and get captured in snapshots indiviually? My Snapshots are done in ZFS on the host. understanding was it just uses the CIFS protocol, but you still gain the benefits of the ZFS File System on the backend. The tough thing is trying to make this fit well in a Windows world. Not really. Samba makes all the OS stuff transparent to the windows user. Just like in Linux. The big change is getting an ECC, snapshotting filesystem on the host. -Craig sharesmb presents ntfs to windows, so you're still hampered by that file system's 'features' such as lots of broadcast packets and a long timeout. One other option you should consider is using NFS, for which you can install a windows client.

In our system, we need to migrating from UFS in a short time. according to the ZFS_Best_Practices_Guide. before migration, we should unshared the UFS, and then umount the ZFS,and then do migration, which means during migration, the service on the machine should stop. but we can't afford the operation for too long time. what can i do?

Re: [zfs-discuss] ZFS Project Hardware
(2) You want a 64-bit CPU. So that probably rules out your P4 machines, unless they were extremely late-model P4s with the EM64T features. Given that file-serving alone is relatively low-CPU, you can get away with practically any 64-bit capable CPU made in the last 4 years. Assuming you're topped out at 4GB RAM by your motherboard, how much difference does 32bit vs 64bit make? Some of the old (cheap) SCSI cards I have only have 32 bit drivers on x86. The cards supported in the 64bit kernel I have to buy, maybe for more then I paid for my motherboard+cpu+RAM. So I'm curious about that point. (5) external cases/enclosures are expensive, but nice. The bang-for-buck is in the workgroup server case, which (besides being a PC case) generally holds 8-10 drives for about $300 or so. Even more bang for the buck: PC case with power supply 42 SATA cables SATA to slot bracket cables disk drive power adapters to SATA power adapters 1-2 120mm fans Bolt the drives into the case. Plug in the power adapters Bolt the SATA to slot brackets in Plug the SATA connectors into the drives. Mount the fan(s) in the case so it pulls air across the drives. Bolt the box up. Now you have drives in a box with SATA ports out the back. Now plug the 42 cables into your server in the SATA ports and feed them out a hole in the case. I label the port numbers on the cables. Plug the 42 cables into the SATA ports of the drives in a box. Power the drives in a box up before your server. I've found this works. SATA isn't sensitive to setup as SCSI was in the past. You did mention this was for a home lab right? I've been running this way in my servers for 4 years. If the solution you really want is an external disk enclosure hooked to some sort of a driver/head machine, check out used/off-lease IBM or HP opteron workstations, which tend to go for $500 or so, loaded. Sun v20z and IBM e326m 1U rackmount servers are in the same price range. -- Erik Trimble Java System Support This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I've thinking about replacing a perfectly-useful Asus power supply that I have in another case with one of the Earthwatts series power supplies, due to the noise. Most of the weirdnesses that I associate with the power supply problems are hard to truly pin on the power supply. But a sub-par power-supply really can affect the stability of the system. Historically AMD CPUs have historically worked, but been unstable when paired with a sub-par power supply (I was able to pin one of these 100% on the power supply). This goes back as far as the original Athlons. Intel CPUs started being finicky around the time the Prescott was released. There are a lot of crappy power supplies out there for sale... I'd advise against skimping on the power supply. I've ordered new cases and/or power supplies for the last three of my home-builds -- and putting a good power supply in there really does correlate (but correlation != causation) with having a stable system. -Luke P.S.

Re: [zfs-discuss] can anyone help me? [SOLVED]
Well, finally managed to solve my issue, thanks to the invaluable help of Victor Latushkin, who I can't thank enough. I'll post a more detailed step-by-step record of what he and I did (well, all credit to him actually) to solve this. Actually, the problem is still there (destroying a huge zvol or clone is slow and takes a LOT of memory, and will die when it runs out of memory), but now I'm able to import my zpool and all is there. What Victor did was hack ZFS (libzfs) to force a rollback to abort the endless destroy, which was re-triggered every time the zpool was imported, as it was inconsistent. With this custom version of libzfs, setting an environment variable makes libzfs to bypass the destroy and jump to rollback, undoing the last destroy command.
