[gentoo-user] nfs mount on client end.
In my home lan setup its an opensolaris (zfs fs) NFS server that is supposed to be set to show NFS vers=3 on offer. Somehow on the client end... my gentoo desktop, its getting mounted with vers=4 as evidenced by the output of `mount' opensolairs_NFS_SERVER:/pub on /pub type nfs (rw,users,addr=192.168.0.29,vers=4,clientaddr=192.168.0.2) Note it says vers=4. I don't see where that is being set. /etc/conf.d/nfs mentiones NFS vers=4 but doesn't say that is what its telling the kernel to use. From /etc/conf.d/nfs # Optional services to include in default `/etc/init.d/nfs start` # For NFSv4 users, you'll want to add rpc.idmapd here. NFS_NEEDED_SERVICES=rpc.idmapd Does that determine what version gets used... it doesn't sound like it would. These lines out of /etc/init.d/nfsmount seems to be the culprit: # Make sure nfs support is loaded in the kernel #64709 if [ -e /proc/modules ] ! grep -qs 'nfs$' /proc/filesystems ; then modprobe -q nfs fi ebegin Mounting NFS filesystems mount -a -t nfs,nfs4 eend $? Or does `mount -a -t nfs,nfs4' just mean vers 4 is made available? I have 2,3 and 4 enabled in the kernel: zcat /proc/config.gz |grep 'NFS[^D].*=' CONFIG_NFS_FS=y CONFIG_NFS_V3=y CONFIG_NFS_V3_ACL=y CONFIG_NFS_V4=y CONFIG_NFS_ACL_SUPPORT=y CONFIG_NFS_COMMON=y There is also a: # CONFIG_NFS_V4_1 is not set But I think that is experimental, and not necessary for vers=4 to be available. So is the linux client supposed to decide which version to mount by what it sees on offer? If so, then is there a known problem when the server is opensolaris? I know opensolaris people tell me to set the server to offer only version=3 because there is some problem with linux if you use version=4. On the opensolaris lists, I've been discussing this, and it appears other users are not having a similar problem when they tell the server to use version=3 which I have (on the opensolaris server in /etc/default/nfs): # Sets the maximum version of the NFS protocol that will be used by # the NFS client. Can be overridden by the vers= NFS mount option. # If vers= is not specified for an NFS mount, this is the version # that will be attempted first. The default is 4. #NFS_CLIENT_VERSMAX=4 # [HP 03/12/09 00:20 NFS_CLIENT_VERSMAX=3 # ] ---- ---=--- - Any input would be helpful..
[gentoo-user] umount nfs share
I'm trying t umount an nfs mounted share but am told the resource is busy. umount -f fails too. So first I turned off all the xterms I had running which should have killed any shell operating there. Still says resouce is busy. So trying to see what is doing it with `lsof' However, when I run `lsof' (no arguments), it fails to produce any output. Just been setting there for 5-6 minutes, now. When I know from past use it should have produced quite a pile of output. I tried a lsof option that is supposed to show specifically nfs related ( lsof -b /nfs/mount/point) So trying it on the one reporting `busy' lsof -b /projects Which gave a gout of output with this kind of stuff in it: lsof: avoiding readlink(/projects): -b was specified. lsof: avoiding readlink(/): -b was specified. lsof: avoiding stat(/): -b was specified. lsof: WARNING: can't stat() rootfs file system / Output information may be incomplete. lsof: avoiding readlink(/): -b was specified. lsof: avoiding stat(/): -b was specified. lsof: WARNING: can't stat() reiserfs file system / Output information may be incomplete.

[gentoo-user] Strategy for using SAN/NAS for storage with Gentoo...
I have recently started looking at server resilience and availability in the context of a hardware failure or hardware upgrade.

Are there any products that offer NFS access? Are any of them secure? * With a SAN, questions of filesystem features are diminished - but questions of access protocol remain. What is best supported by gentoo? * Do any gentooists have any inexpensive hardware configurations that work especially well? Any hints or tips?

Someone here, a yr or two ago recommended to me when I asked that question to install opensolaris on a machine and set it up as NAS. Opensolaris offers the zfs file system, that is really advanced compared to others. I'll admit I've had some issues along the way. And have to do lots of boning up on opensolaris. I access the zfs server by cifs from windows machines, and by NFS from linux. Opensolaris doesn't use samba by default. Instead they have their own CIFS server which works fine. They do have samba pkgs but no one hardly use it, preferring their CIFS server. Mine is only a home lan setup, but even then the opensolaris server has over a terabyte of capacity. I have it setup in 3 mirrors of 2 disks each. 2 prs of 500gb sata hdd and one pr of 750 sata hdd There are many ways so setup `zraid' systems on `zfs' that are excellent for reliability. ( I have been told I haven't tried that route). For me the mirror setup seemed good for my small needs. Even more reliable I'm told, if a bit higher in disk usage. opensolaris zfs fs offers a `timeslider' interface to a system of snapshotting the filesystems in 15 min, 1hr 1day etc snapshots in a very small footprint way. You'd have to read up on it.. It would take too much off topic to cover here. The system takes an amazing small amount of disk space for the snapshots based on COW (Copy on write). There was talk of opensolaris going by the wayside with the Oracle takeover of Sun... but Oracle has since announced its intention of puttin even more resources into `opensolaris' development than Sun was doing. These may be a good intro to zfs: http://www.sun.com/bigadmin/features/articles/zfs_part1.scalable.jsp http://all-unix.blogspot.com/2007/03/zfs-cow-and-relate-features.html http://wikis.sun.com/display/OpenSolarisInfoPL/How+to+Manage+the+Automatic+ZFS+Snapshot+Service

I have to admit, I do like the idea of ZFS, though not quite enough to justify maintaining Solaris in addition to my other infrastructure. I was thinking about something rather different entirely. I was thinking about bunging disk on my LAN and shifting as much data from local storage on my server as possible. This would mean that the server could be swapped out with minimum effort. If 'disk on the net' allowed mirroring etc. then storage could be expanded and contracted as necessary without any downtime... essentially, only my hub would then be a single-point-of-failure. I'd love to be able to run a VM on my desktop, for example, and use that as a 'stand-in' while I take-down my main server for maintenance. For this to work, I'd need to access the same file system and be able to switch responsibility for services between the two 'servers' quickly. From ages ago, I remember iSCSI being bandied about.

I believe it is quite widely used - it is mentioned often on the linux- poweredge list. I would imagine the Linux kernel allows mounting and sharing by iSCSI - check `make menuconfig` and type /iscsi. It's hard to be more specific without knowing your usage. For storage of a mere terabyte you can buy a networked storage enclosure which will accommodate two drives. These are cheap, do mirroring, will accommodate standard 1TB, 1.5TB, 2TB drives, but are probably not too fast. One reads a lot posted by people who have large movie collections stored on the network, whether they be MythTV users or the mutineer sailors of 17th century galleons. A PC-based solution gives you more room for this - you can fit perhaps 4 drives in a standard PC case you find at the tip, or you can get 12 or 16 drives in a dedicated rackmount server case. This allows capacity of upto 32TB with current drives, if you can afford that, or to use cheaper drives (1TB or 1.5TB are best gigabytes-per-dollar at present, I think; 500gb drives seem recently to have become disproportionately expensive) and have better RAID levels. The Norco one is popular amongst enthusiasts, because it's really cheap [1]; it uses 2 x standard ATX power supplies, one for the mainboard, one for the drives. You can get similar cases with the option of hot-swap PSUs - Chenbro used to be the main brand for this, I think, but in the last couple of years TST http://TSTcom.com have started producing nicer cases; I use a TST ESR-316, which is utterly lush, but which was expensive. I have one slight reservation about the TST, which I will not spend time detailing unless you ask. I use only half the TST's capacity at present, but it is a pleasure and a relief to have so much room available; expansion of network drive capacity is never a problem - just slap a drive in and you're ready to go. Even with as many as 6 or 8 drive bays there are corner cases which can make expansion a bit of a headache (at least if uptime is important). Since these cases accommodate standard ATX motherboards, you get to use an old Pentium 4 motherboard salvaged from an old PC or an Atom- based motherboard for £100 or so. The latter price is a bit shocking, IMO, compared to (say) the Asus EE-PC, but it reflects the demand for them; they're prolly only $100 in the US. These atom motherboards have minimal expansion slots, but if you only want to use it for storage then you're probably fine with just one. If you build your own server you can use software or hardware RAID. Fast hardware RAID, based on an PCIe controller card, is expensive. You can get PCI or PCI-X hardware RAID very cheaply on eBay these days, but it's slow. That is to say that PCI or PCI-X hardware RAID is fast enough to stream a couple of movies at the same time, fast enough to copy 5gb files only a couple of minutes, but production server systems (if you were buying a database server for work) would be expected to use a PCIe-based hard-drive controller. Hardware RAID is nice in its ability to hot-swap out a failed hard-drive without interruption. I have not found non-RAID SATA controllers that satisfy me with their ability to do hot-swap (although I would love to). Managing RAID on a PC-based server - rather than a dedicated NAS enclosure - very easily allows expansion. With RAID5 or 6 you can just add in another drive and expand on to it. I use an old PCI-X (fits in a PCI slot) 3ware 9500 card, and it *seems* like if you have a RAID1 (haven't tried RAID5) on two drives of capacity X, then remove each of those drives in turn, rebuilding onto drives of X+Y capacity, then upon completion the array appears to the o/s as the larger X+Y size. I think some LSI cards do this, also. I would not bet on the ability of low-end NAS boxes to do this. A company called Drobo makes some high-end NAS hardware with space for plenty of drives (on some models) and some fancy features. I find UK prices a bit shocking, but depending upon your application they might be justified; the US prices seem quite reasonable to me. I wouldn't get too het up about Samba / CIFS vs NFS. Samba / CIFS can be faster than NFS, even in an all-Linux environment. Other times it's not. This seems pretty much random, depending upon whom is doing the benchmarking. On an intellectual level, at least, I find neither wholly satisfying - it would be really nice to have a Linux-native network filesystem that does authentication / permissions properly. But both do work. I looked at ZFS, but decided that Solaris, from a look at the HCL, was too picky over hardware. I think ZFS is great, I no longer think it's the future. My selection of cheap hardware is far wider under Linux, I

These are cheap, do mirroring, will accommodate standard 1TB, 1.5TB, 2TB drives, but are probably not too fast. A cheap NAS enclosure is a definite possibility - there'd be no performance issue - though this leaves three key questions: 1) Will it support unix file-permissions and can I be (fairly sure) it will be secure if someone hacks my Wi-Fi? 2) Will I be able to put the (majority of the) gentoo filesystem on it - or will I need to have a fully booted system to connect? 3) Can I use two entirely separate devices and mirror to both? (I expect the failure of the enclosure to be at least as likely as the failure of a drive.) If you build your own server you can use software or hardware RAID. Hmmm... building my own server - I've done that in the past, but my plan is to minimize DIY with a view to minimizing the number of components that might fail. Ideally, I'd have four devices - one with a CPU and memory (the server)... booting from Flash or CD or whatever (+a replacement in the cupboard); two separate boxes with drives in them (mirrored storage); one (wired) Ethernet hub and broadband gateway. I'd connect to the network from a separate desktop/laptop to interact with it - either locally or remotely. I wouldn't get too het up about Samba / CIFS vs NFS. Samba / CIFS can be faster than NFS, even in an all-Linux environment. Other times it's not. This seems pretty much random, depending upon whom is doing the benchmarking. On an intellectual level, at least, I find neither wholly satisfying - it would be really nice to have a Linux-native network filesystem that does authentication / permissions properly. But both do work. Well the 'server' will be running Samba - and it's the back-end storage for that I'm trying to resolve. CIFS definitely looks problematic - since Unix permissions for server data are one valuable separation between publicly accessible services and my private data. NFS might be OK (it doesn't feel great) - though I *really* don't want to move from one server to two when I'm aiming for reliability. I looked at ZFS, but decided that Solaris, from a look at the HCL, was too picky over hardware. I think ZFS is great, I no longer think it's the future. My selection of cheap hardware is far wider under Linux, I can install Gentoo and just `emerge mediatomb` and stream movies to my PS3. I like ZFS, conceptually, though I don't like Solaris. I'm aware that Apple have toyed with adopting ZFS and that it is available for BSD... A *really* neat solution would be a (pair of) cheap NAS devices running an appliance distribution of BSD with ZFS - exporting a NFS mount... possibly over a VPN? Hmmm - I'm trying to avoid complexity, too. Hmmm.
[gentoo-user] getting firmware for orinoco pcmcia card
I am installing gentoo on an old machine without wireless builtin. I have a hermes/orinoco pcmcia card that works fine. Indeed the wireless works fine, but is not right. When booting there is a very long delay at the net.eth1 and the system wants the agere_sta_fw.bin firmware. If you wait it out, it eventually proceeds and the wireless works. I assume I should be getting the firmware, but I don't know from where. I did emerge the orinoco-fwutils but that doesn't have firmware or say where to get it. Any help would be appreciated. thanks, allan

Re: [gentoo-user] Re: Strategy for using SAN/NAS for storage with Gentoo...
Hi, The budget is miniscule - and the performance demands (bandwidth and latency) are completely non-challenging. This IMHO pretty much rules out any kind of server-class hardware, which tends to be both costly and power-hungry. If you're thinking about buying used stuff, be sure to factor in the cost and difficulty of finding spares in some years' time. Given the point above I would also stick with software RAID. True HW RAID controllers are quite expensive and generally come with a x8 PCIe interface which will require a server motherboard -- x16 PCIe video card slots in commodity boards are usually only certified for x16 and x1 operation, so don't expect them to work reliably with other bus widths. Linux software RAID also has the advantage that the kernel is not tied to any specific piece of hardware. In case of a failure, your volumes will be readable on any other Linux system -- provided the disks themselves are not toast. If reliability is your primary concern, I would go for a simple RAID1 setup; if your volumes need to be bigger than a physical disk you can build a spanned volume over multiple mirrored pairs. Network throughput will mostly likely be your primary bottleneck, so I'd avoid striping as it would offer little in the way of performace at the expense of making data recovery extremely difficult in case the worst should happen. As for availability, I think the best strategy with a limited budget is to focus on reducing downtime: make sure your data can survive the failure of any single component, and choose hardware that you can get easily and for a reasonable price. Sh*t happens, so make it painless to clean up. Network protocol: If you do not need data sharing (i.e. if your volumes are only mounted by one client at a time), the simplest solution is to completely avoid having a FS on the storage server side -- just export the raw block device via iSCSI, and do everything on the client. In my experience this also works very well with Windows clients using the free MS iSCSI initiator. Alternatively, you can consider good old NFS, which performs decently and tends to behave a bit better -- especially when used over UDP -- in case of network glitches, like accidentally powering off a switch, yanking cables, losing wireless connectivity... CIFS should be avoided at all costs if your clients are not Windows machines. File systems: avoid complexity. As technically superior as it might be, in this kind of setup ZFS is only going to be resource hog and a maintenance headache; your priority should be having a rock-solid implementation and a reliable set of diagnostic/repair tools in case disaster strikes. Tried-and-true ext3 fits the bill nicely if you ask me; just remember to tune it properly according to your planned use -- eg. if a volume is going to be used to host huge VM disk images, be sure to create its filesystem with -T largefile4. Just my 2 cents, Andrea

I look at the differences in the Portage tree before and after. For builds, is it really wise to do all updates unattended? Perfectly. The emerge runs the same whether in background or foreground.

I'm sure you have a good reason for wanting to do things your way, and I do not claim mine is better. I am just surprised that you sounded surprised to find out some people don't do things your way. Perhaps it is because I became used to running long-winded jobs in the background years ago on mainframes. It was always the case that using the terminal as the primary output device slowed down the job, because spooling the output to disk was always faster than displaying it on the terminal. I believe that to be so to this very day. Actually, the cron daemon won't run because I don't have a cron daemon installed on the laptop. And I don't have a cron daemon because having periodic jobs only make sense if the computer is likely to be on when cron is triggered. Using a modern cron daemon is a convenient way to run regular jobs, even on a machine that is powered off for much of the time. One can use the first option to kick off jobs relative to power-on time instead of wall clock time. -- Regards, Dave [RLU #314465] == dwn...@ntlworld.com (David W Noon) == signature.asc Description: PGP signature
