zfs.ko missing after update to 12.10

[RealityMaster]

I updated to 12.10 from 12.04 and the zfs module for the new version is missing.

# zpool list
Failed to load ZFS module stack.
Load the module manually by running 'insmod <location>/zfs.ko' as root.

So I looked for it...

# uname -a
Linux Gollum 3.5.0-21-generic #32-Ubuntu SMP Tue Dec 11 18:51:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

# find /lib/modules -name zfs.ko
/lib/modules/3.5.0-20-generic/updates/dkms/zfs.ko
/lib/modules/3.5.0-19-generic/updates/dkms/zfs.ko

So I tried removing and re-installing zfs,

apt-get remove ubuntu-zfs
apt-get autoclean
...reboot...
apt-get install ubuntu-zfs

(That's a summation....it was successful but same result)

Does anyone have 3.5.0-21-generic ... /zfs.ko ?

i have no clue about that zfs module, but have you tried modprobe ?

I don't use ZFS but have watching its progress with Ubuntu.

Read this blog thread on ZFS with Ubuntu 12.04

Pay attention to the NOTE:
Note: The necessary GRUB package will not be published for Ubuntu 12.10 Quantal Quetzal. This issue will be revisited for the next release series.

You might want to ask the author of that Blog "why" that Note says what it says as he doesn't go into any details beyond the above.

Unfortunately yes, but it fails as the file is not present..

 modprobe zfs
FATAL: Module zfs not found.

Unfortunately I'm not booting zfs, I'm just using it to house an array, so I don't really need grub-zfs

bump ?

Ran updates today and it's working again!!!!

# find /lib/modules -name zfs.ko
/lib/modules/3.5.0-21-generic/updates/dkms/zfs.ko

I'm having the same problem.

I've been running ZFS on 12.10 for a few weeks with no issues, today I rebooted as apt had upgraded the kernel and now ZFS is broken.

This is the PPA I'm using: https://launchpad.net/~zfs-native/+archive/stable

Here's what I've tried so far:

$ uname -a
Linux Goon 3.5.0-21-generic #32-Ubuntu SMP Tue Dec 11 18:51:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

$ sudo zpool list
Failed to load ZFS module stack.
Load the module manually by running 'insmod <location>/zfs.ko' as root.

$ find /lib/modules -name zfs.ko
/lib/modules/3.5.0-19-generic/updates/dkms/zfs.ko

$ sudo insmod /lib/modules/3.5.0-19-generic/updates/dkms/zfs.ko
insmod: error inserting '/lib/modules/3.5.0-19-generic/updates/dkms/zfs.ko': -1 Unknown symbol in module

$ sudo modprobe zfs
FATAL: Module zfs not found.

$ sudo dmesg | grep zfs:
[ 1380.577459] zfs: Unknown symbol __taskq_destroy (err 0)
[ 1380.577472] zfs: Unknown symbol spl_cleanup (err 0)
[ 1380.577480] zfs: Unknown symbol nvpair_value_uint8 (err 0)
[ 1380.577487] zfs: Unknown symbol kmem_debugging (err 0)
[ 1380.577501] zfs: Unknown symbol vn_openat (err 0)

- this continues for hundreds of lines -

Now it seems to me that the zfs.ko module should be in

/lib/modules/3.5.0-21-generic/updates/dkms/zfs.ko

instead of

/lib/modules/3.5.0-19-generic/updates/dkms/zfs.ko

but I've no idea how to solve this.

Any ideas?

Update: I've added the daily PPA and upgraded which seems to have solved the problem. Though I don't feel too comfortable using the unstable branch on my production filesystem, so still looking for solutions on this! I guess if it comes to it I'll just wait for stable to be updated again and switch back.

Just thought I'd chime in. I also switched to the Daily PPA. I reinstalled everything, but the zfs-dkms package is the one that fixed it. So if you've tried Daily PPA and reinstalling ubuntu-zfs, try reinstalling zfs-dkms. I'm good to go now.

[RealityMaster]

Great balls of FIRE!!!!

This is the third update to cause this problem!!! RAWWRRR!!

Is no one testing the zfs package before updates are pushed?
I'll assume not as it's not officially supported, but this is getting $^(k!n& annoying.
