Public bug reported:
I have a virtual machine that locks up every time any file access is
done to the mounted ocsfs2 shared volume. the volume is backed by vmware
multiwriter virtual disk.
I do not have a lot of diagnostics other than the various dmesg logs
it seems to be an ocfs2 issue or at least ocfs2 is "crashing"
when this happens the ssh session locks up and is un usable.
and as a result of monitoring services that try to read disk status the cpu
load goes high
attempts to reboot the vm during this state sometimes result in
user@hostname:~$ sudo shutdown -r now
Failed to start reboot.target: Connection timed out
See system logs and 'systemctl status reboot.target' for details.
