Just now I did an apt-get upgrade, which upgraded package spl to 0.6.4.1. After rebooting, my zfs-formatted disk failed to mount. How should I regain zfs functionality?
All zfs commands are now aborting with
Failed to load ZFS module stack.
Load the module manually by running 'insmod <location>/zfs.ko' as root.
When I follow that instruction, insmod /var/lib/dkms/zfs/0.6.3/3.13.0-49-generic/x86_64/module/zfs.ko
fails as well:
error inserting '/var/lib/.../zfs.ko': -1 Unknown symbol in module
The OS, according to /etc/lsb-release
and uname -a
, is
12.04.5 LTS
Linux 3.13.0-49-generic #81~precise1-Ubuntu SMP Wed Mar 25 ... x86_64 x86_64 x86_64
Perhaps the upgraded spl package is incompatible with the other zfs packages,
because dkms status
reports 0.6.4.1 vs. 0.6.3:

But apt-cache policy spl
reports that the only version of spl is 0.6.4.1-1~precise
, so I can't un-upgrade spl even if I wanted to.
The other zfs packages installed are, from dpkg --get-selections
:
libzfs1 ubuntu-zfs zfs-auto-snapshot zfs-dkms zfsutils
I'd prefer to stick to Ubuntu packages, instead of (say) manually installing spl-0.6.3 from http://zfsonlinux.org/ . That might break things even worse.

How should I recover from this? Where should I investigate further?
sudo apt-get update; sudo apt-get dist-upgrade
to get zfs upgraded too? Please include full output of the commandsgrep -rF zfs /etc/apt
andapt-cache policy zfs-dkms spl-dkms
. It could also be possible your zfs packages have been upgraded perfectly fine, but the DKMS build failed for some reason.linux-image-generic-lts-trusty
kernel you appear to be running (3.13 backported from Trusty to Precise) and fail on the DKMS build. It may help to change the ppa source to trusty for you, or to revert the kernel to a supported one for ZFS. Just guessing though.sudo apt-get install ubuntu-zfs zfs-dkms
and provide full output. It should mention an error in the upgrade/postinstall configuration, because the new 0.6.4.1 version is perfectly a new installable candidate. I'm sure you've overlooked some pretty fatal error messages during your previous upgrade command. I think your apt output will mention a DKMS error log, please provide that output too (or on paste.ubuntu.com or something.) :)zfs mount -a
appears to do nothing, andzfs list
saysno pools available
