<blockquote>Hello,
<br>
<br>
After updating one of our OpenVZ VPS hosting nodes at the end of
last week, we've started to have issues with corruption apparently
occurring inside containers. Issues of this nature have never
affected the node previously, and there do not appear to be any
hardware issues that could explain this.
<br>
<br>
Specifically, a few hours after updating, we began to see
containers experiencing errors such as this in the logs:
<br>
<br>
[90471.678994] EXT4-fs (ploop35454p1): error count since last
fsck: 25
<br>
[90471.679022] EXT4-fs (ploop35454p1): initial error at time
1593205255: ext4_ext_find_extent:904: inode 136399
<br>
[90471.679030] EXT4-fs (ploop35454p1): last error at time
1593232922: ext4_ext_find_extent:904: inode 136399
<br>
[95189.954569] EXT4-fs (ploop42983p1): error count since last
fsck: 67
<br>
[95189.954582] EXT4-fs (ploop42983p1): initial error at time
1593210174: htree_dirblock_to_tree:918: inode 926441: block
3683060
<br>
[95189.954589] EXT4-fs (ploop42983p1): last error at time
1593276902: ext4_iget:4435: inode 1849777
<br>
[95714.207432] EXT4-fs (ploop60706p1): error count since last
fsck: 42
<br>
[95714.207447] EXT4-fs (ploop60706p1): initial error at time
1593210489: ext4_ext_find_extent:904: inode 136272
<br>
[95714.207452] EXT4-fs (ploop60706p1): last error at time
1593231063: ext4_ext_find_extent:904: inode 136272
<br>
<br>
Shutting the containers down and manually mounting and e2fsck'ing
their filesystems did clear these errors, but each of the
containers (which were mostly used for running Plesk) had
widespread issues with corrupt or missing files after the fsck's
completed, necessitating their being restored from backup.
<br>
<br>
Concurrently, we also began to see messages like this appearing in
/var/log/vzctl.log, which again have never appeared at any point
prior to this update being installed:
<br>
<br>
/var/log/vzctl.log:2020-06-26T21:05:19+0100 : Error in fill_hole
(check.c:240): Warning: ploop image
'/vz/private/8288448/root.hdd/root.hds' is sparse
<br>
/var/log/vzctl.log:2020-06-26T21:09:41+0100 : Error in fill_hole
(check.c:240): Warning: ploop image
'/vz/private/8288450/root.hdd/root.hds' is sparse
<br>
/var/log/vzctl.log:2020-06-26T21:16:22+0100 : Error in fill_hole
(check.c:240): Warning: ploop image
'/vz/private/8288451/root.hdd/root.hds' is sparse
<br>
/var/log/vzctl.log:2020-06-26T21:19:57+0100 : Error in fill_hole
(check.c:240): Warning: ploop image
'/vz/private/8288452/root.hdd/root.hds' is sparse
<br>
<br>
The basic procedure we follow when updating our nodes is as
follows:
<br>
<br>
1, Update the standby node we keep spare for this process
<br>
2. vzmigrate all containers from the live node being updated to
the standby node
<br>
3. Update the live node
<br>
4. Reboot the live node
<br>
5. vzmigrate the containers from the standby node back to the live
node they originally came from
<br>
<br>
So the only tool which has been used to affect these containers is
'vzmigrate' itself, so I'm at something of a loss as to how to
explain the root.hdd images for these containers containing sparse
gaps. This is something we have never done, as we have always
been aware that OpenVZ does not support their use inside a
container's hard drive image. And the fact that these images have
suddenly become sparse at the same time they have started to
exhibit filesystem corruption is somewhat concerning.
<br>
<br>
We can restore all affected containers from backups, but I wanted
to get in touch with the list to see if anyone else at any other
site has experienced these or similar issues after applying the
7.0.14 (136) update.
<br>
<br>
Thank you,
<br>
Kevin Drysdale.
