[Bug 1654708] Re: Trying to reinstall ZFS on Xenial. Cannot mount existing zpool with identifier from /mnt/disk/by-id/xxxx

[Colin Ian King]

This was fixed with:

zfs-linux (0.6.5.6-0ubuntu16) xenial; urgency=medium

  * Enable zfs to respect RSIZE_LIMIT limits (LP: #1656259)
- backport of zfs upstream commit 4b908d32200b6e5c7b5115322b6c8d25e770daa0
  ("Linux 4.8 compat: posix_acl_valid()") to facilitate changes in 
posix_acl_valid.
  1015-Linux-4.8-compat-posix_acl_valid.patch
- backport of upstream commit 933ec999511f3d29de005bfa8966ae007b161c0f
  ("Retire .write/.read file operations")
  1016-Retire-.write-.read-file-operations.patch

with upstream commit:

commit 4b908d32200b6e5c7b5115322b6c8d25e770daa0
Author: Brian Behlendorf 
Date: Tue Aug 2 11:11:45 2016 -0700

Linux 4.8 compat: posix_acl_valid()

The posix_acl_valid() function has been updated to require a
user namespace. Filesystem callers should normally provide the
user_ns from the super block associcated with the ACL; the
zpl_posix_acl_valid() wrapper has been added for this purpose.
See https://github.com/torvalds/linux/commit/0d4d717f for
complete details.

[Bug 1654708] Re: Trying to reinstall ZFS on Xenial. Cannot mount existing zpool with identifier from /mnt/disk/by-id/xxxx

[John Bridges]

I just upgraded from 14.04 to 16.04  4.4.0-64-generic

At first the modprobe zfs seemed to work if done manually after boot.
Once I removed zfsutils-linux, and re-installed it would no longer work.
I tried multiple variations of removing and re-adding ZFS, and did purge all 
old ZFS versions from Trusty install.

The only fix I could get to function was to modify the source for zpl_xattr.c
There were two calls to posix_acl_valid, one in __zpl_xattr_acl_set_access, and 
one in __zpl_xattr_acl_set_default.
I changed them as described above, and did dpkg-reconfigure zfs-dkms

The ZFS kernel module would not load until I rebooted, then it all came
up and mounted my ZFS pools automatically.

It appears this fix is already in the master ZFS on Linux source:
https://github.com/zfsonlinux/zfs/blob/master/module/zfs/zpl_xattr.c

Hopefully this will end up in Ubuntu soon?

[Sam Bouwer]

Just did a fresh install with an dist-upgrade to 4.4.0-64, and

apt-get install zfs

worked just fine:). After reboot the exported zpools were automatically
imported.

[Bug 1654708] Re: Trying to reinstall ZFS on Xenial. Cannot mount existing zpool with identifier from /mnt/disk/by-id/xxxx

[Sam Bouwer]

Had the same issue. I was unable to import my zpools after a clean
install (I did a zpool export before the reinstall).

I'm running the following version of Ubuntu:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:Ubuntu 16.04.2 LTS
Release:16.04
Codename:   xenial

I'm running the following kernel version:

$ uname -a
Linux UniServer 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:09:55 UTC 2017 
i686 i686 i686 GNU/Linux

I've edited the file mentioned in post #6, rebooted, ran the commands
and tried to check the status of the zpools. They were already imported!
Issue solved.

Thank you Michael T. for your post!

I ran into this same problem today on an update.

The above fix in #6 worked for me on:

Ubuntu 16.04.2 LTS

4.4.0-62-generic

The DKMS modules now compile after editing
/usr/src/zfs-0.6.5.6/module/zfs/zpl_xattr.c

[Peter Goodall]

Hello all,

I believe a fix was just delivered to my workstation. It failed to build on my 
machine. I have attached the log at:
/var/lib/dkms/zfs/0.6.5.6/build/make.log

An automated error report should appear attached to this topic as well.
Not sure how that error report gets delivered. If i need to submit any
more files - please let me know.

Cheers...

Some more details


A posix function in kernel has changed between 4.4.0-57 and 4.4.0-59

./linux-headers-4.4.0-53/include/linux/posix_acl.h:extern int 
posix_acl_valid(const struct posix_acl *);
./linux-headers-4.4.0-57/include/linux/posix_acl.h:extern int 
posix_acl_valid(const struct posix_acl *);
./linux-headers-4.4.0-59/include/linux/posix_acl.h:extern int 
posix_acl_valid(struct user_namespace *, const struct posix_acl *);
./linux-headers-4.4.0-62/include/linux/posix_acl.h:extern int 
posix_acl_valid(struct user_namespace *, const struct posix_acl *);


The zfs kernel modul is not updated to match these changes.
see: 
https://fossies.org/diffs/zfs/0.6.5.7_vs_0.6.5.8/module/zfs/zpl_xattr.c-diff.html

I have tried the following:

Replaced all occurrences
   error = posix_acl_valid(acl);
with 
   error = posix_acl_valid(ip, acl);
in file:
/usr/src/zfs-0.6.5.6/module/zfs/zpl_xattr.c

 dkms remove -m zfs -v 0.6.5.6 -k 4.4.0-62-generic
 dkms install --force -m zfs -v 0.6.5.6 -k 4.4.0-62-generic 
does compiles now.

System seems to work.

[Milos Leskanic]

Problem persists with kernel 4.4.0-62. Looks like the only hope left is
to wait for 16.04.2 point release (currently pushed out to Feb 9) and
see how things go with (HWE) kernel 4.8. Did anyone give it a chance
earlier by trying out hwe-16.04-edge kernel package?

Hi Michael,

Looks like this email was direct from you. I'm just a user that reported
the bug using the reporting system in Xenia. No hope in hell of me fixing
it :-)
I'm not even really sure how you should add your feedback to the bug
reporting system.

Cheers,

[Bug 1654708] Re: Trying to reinstall ZFS on Xenial. Cannot mount existing zpool with identifier from /mnt/disk/by-id/xxxx

[Michael T.]

zfs is killed with kernel update in xenial similar as with 14.04:
https://github.com/zfsonlinux/zfs/issues/5408
https://github.com/zfsonlinux/pkg-zfs/issues/219

The 14.04 issue fixed.
