We set volume to ILLEGAL when we merge the top volume into the parent volume,
and both volumes contain the same data.
After we mark the volume as ILLEGAL, we pivot to the parent volume
(8e412b5a-85ec-4c53-a5b8-dfb4d6d987b8).
If the pivot was successful, the parent volume may have new data, and starting
the vm using the top volume may corrupt the vm filesystem. The ILLEGAL state
prevent this.
If the pivot was not successful, the vm must be started using the top
volume, but it
will always fail if the volume is ILLEGAL.
If the volume is ILLEGAL, trying to merge again when the VM is not running will
always fail, since vdsm does not if the pivot succeeded or not, and cannot merge
the volume in a safe way.
Do you have the vdsm from all merge attempts on this disk?
This is an extract of the vdsm logs, i may provide the complete log if it would help.
Yes, this is only the start of the merge. We see the success message
but this only means the merge
job was started.
Please share the complete log, and if needed the next log. The
important messages we look for are:
Requesting pivot to complete active layer commit ...
Follow by:
Pivot completed ...
If pivot failed, we expect to see this message:
Pivot failed: ...
After these messages we may find very important logs that explain why
your disk was left
in an inconsistent state.
Since this looks like a bug and may be useful to others, I think it is
time to file a vdsm bug,
and attach the logs to the bug.
