Arch Linux User Repository

!IMPORTANT! For users that are using ZFS as root, there is a problem with the current package when generating the ramdisk with mkinitcpio. The problem is that once the kernel is installed, the mkinitcpio is initiated before the ZFS packages have been installed. This produces errors because mkinitcpio cannot find the ZFS binaries needed by the install hook. To fix this, use: # depmod -a 3.6.10-1-ARCH # mkinitcpio -p linux

The packages and repository have been updated for kernel 3.6.10.

Indeed, ZFS does not build against Kernel 3.7. In order not to have these packages be flagged out of date for an extended period of time, I have created patches for ZFS and SPL including the fixes from the ZOL master branches and packaged them using pkgrel 8. http://demizerone.com/archzfs/pkgsrc/aur/spl-utils-0.6.0_rc12-8.src.tar.gz http://demizerone.com/archzfs/pkgsrc/aur/spl-0.6.0_rc12-8.src.tar.gz http://demizerone.com/archzfs/pkgsrc/aur/zfs-utils-0.6.0_rc12-8.src.tar.gz http://demizerone.com/archzfs/pkgsrc/aur/zfs-0.6.0_rc12-8.src.tar.gz The patch includes all the changes made up until the last release. ZOL is very weird in how they make releases, they are no rhyme or reason to them, they just happen and it seems anything that touches the master branch is stable. I have been running these updated packages for a couple days without incident. I also have the packages for 3.6.10 ready to go (pkgrel-7), I am just waiting for 3.6.10 to hit [core]. http://demizerone.com/archzfs/pkgsrc/aur/spl-utils-0.6.0_rc12-7.src.tar.gz http://demizerone.com/archzfs/pkgsrc/aur/spl-0.6.0_rc12-7.src.tar.gz http://demizerone.com/archzfs/pkgsrc/aur/zfs-utils-0.6.0_rc12-7.src.tar.gz http://demizerone.com/archzfs/pkgsrc/aur/zfs-0.6.0_rc12-7.src.tar.gz I am thinking about creating a testing repository for these packages so I can push updates out for testing. In other news, I have created a branch that tracks the archiso so we can do emergency maintenance if need be. The server string for pacman.conf is as follows: [archzfs] Server = http://demizerone.com/$repo/archiso/$arch Of course, you will also need to add my key and locally sign it before using, but now we can use zfs in the archiso environment without compiling! I have installed ZFS on a root filesystem on my wife's laptop, there are changes coming to the packaging to improve the implementation. Most of all I am working on updating the archwiki documentation and that should be up in the next week or two.

@proxypoke: That has been fixed in the latest zfs git :) You can clone the git repo (https://github.com/zfsonlinux/zfs.git) and run ./autogen.sh ./configure make pkg which will create Arch Linux .pkg.tar.xz packages you can install.

Ahoy all, ZFS doesn't compile on Linux 3.7.0 yet. I tested this with the ck patchset, but it should be the same on the standard kernel. It gives an error about GPL-only symbols when linking zfs.ko. Short error log attached: https://gist.github.com/4285774 I'd advise against kernel updates if you need ZFS. Cheers slowpoke

The ZFS package has been updated to pkgrel 5 and now supports for kernel 3.6.8. Changes include: * mkinitcpio hooks rewrite thanks to falconindy. * Removed support for spl_hostid kernel parameter. * Rewrite of systemd unit file thanks to duncant. * Experimental handling of /etc/hostid. /etc/hostid is now tracked by the spl-utils package. * Rewrite package descriptions. I apologize in advance for the long post, but a lot has changed. The systemd unit rewrite now properly loads the kernel modules with modprobe and also exports the zfs shares. The mkinitcpio hooks have been rewritten to support the next version of mkinitcpio. The spl-utils package now tracks the /etc/hostid file. This file is used by zfs to include in the storage pool metadata when creating pools. In some cases if this value differs from /etc/hostid and the pool metadata, zfs will refuse to import the pool producing an error saying that the foreign pool could not be imported. Supposedly, the hostid command produces a 32 bit unique identifier on every fresh reboot using the systems IP address. So the hostid gathered when you created the pool can be different from what the hostid command currently produces. I say supposedly because in my tests, my hostid has not changed from boot to boot. This could be because I use a static IP address though. The hostid used when creating your zfs pools can be gathered by using the command "zdb". The /etc/hostid file itself is a 4 byte little endian binary file. So `echo $(hostid) >/etc/hostid` is not the proper way to set the hostid value. One way to set the hostid is the following: HOSTID=$(hostid) sudo sh -c "printf $(echo -n $HOSTID | sed 's/\(..\)\(..\)\(..\)\(..\)/\\x\4\\x\3\\x\2\\x\1/') >/etc/hostid" You could also make a quick and dirty C program that calls sethostid(id). The spl-utils package now tracks the /etc/hostid file. If it already exists on your system, you will need to record the value somewhere and let the spl-utils package overwrite it using "pacman -Sf" (or delete the file yourself). If the value in your /etc/hostid is correctly set, than you can retrieve it using the following command: $ od -A n -t x1 /etc/hostid > 00 01 7f 00 Note: If correctly set, this value will have the low-order byte first, so it will have to be saved back to /etc/hostid with: sudo sh -c "printf $(echo -n 00017F00 | sed 's/\(..\)\(..\)\(..\)\(..\)/\\x\1\\x\2\\x\3\\x\4/') >/etc/hostid" The value produced should be only 4 bytes! If it is not, then it is okay to let the spl-utils post_install hook produce a proper hostid for you. Since the proper hostid is now included in the initramfs, I dropped support for the spl_hostid kernel parameter check in the initcpio hook. All it did anyways was echo the value to /etc/hostid, which is incorrect. NOTE: If you are using this parameter, you will be kicked out to the repair command line in the initramfs! You should now instead use the method described above to set this value to /etc/hostid. You will then need to rebuild your initramfs with "mkinitcpio -p linux". One last thing, To be on the safe side, make sure you have good backups before performing any updates ALWAYS. Whew! - demizer

The ZFS packages have been flagged out of date. Kernel 3.6.8 is now in [core]. I am currently working on fixing hostid issues in the spl package. The new packages should be uploaded to AUR within the next day or two. Thanks!
