ocfs2 shared volume causing hang

[Jason Grammenos]

This vm is running on a vmware backed system with a multiwriter shared volume mounted via ocfs2.
in kernel version 4.4.0-187 or -189 any attempt at writting to the volume results in kernel errors

root@hostname:/mnt/NewsroomImageShare# touch text.txt
Killed

kernel version 186 this issue does not occur.

root@hostname:~# lsb_release -rd
Description: Ubuntu 16.04.7 LTS
Release: 16.04

package
ii linux-image-4.4.0-187-generic 4.4.0-187.217 amd64 Signed kernel image generic

what I expect to happen: writing to a ocfs2 shared disk should not crash
what happens: writting to an ocfs2 shared disk crashes the terminal/ssh session, and make the vm unusable. and logs errors in dmesg

I see the same problem with Ubuntu 18 and Kernel 4.15.0-115 and 117. Massive trouble on ocfs2 based mounts. Writing isn't possible. A serious issue as all clustered systems are not working. Processes trying to write on the filesystem are hanging without any chance to kill them except a reboot.

Status changed to 'Confirmed' because the bug affects multiple users.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1895010

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Jason Grammenos (jason.grammenos.agility)]

hopefully this ticket gets some notice soon as this bug appears to be a kernel level regression in a "major" kernel level feature: ocfs2
