What if we move all vm off the lun which causes this error, drop the
and recreated it. Will we "migrate" the error with the VM to a different
lun or could this be a fix?
This should will fix the ids file, but since we don't know why this corruption
happened, it may happen again.
Please open a bug with the log I requested so we can investigate this issue.
To fix the ids file you don't have to recreate the lun, just
initialize the ids lv.
1. Put the domain to maintenance (via engine)
No host should access it while you reconstruct the ids file
2. Activate the ids lv
You may need to connect to this iscsi target first, unless you have other
vgs connected on the same target.
lvchange -ay sd_uuid/ids
3. Initialize the lockspace
sanlock direct init -s <sd_uuid>:0:/dev/<sd_uuid>/ids:0
4. Deactivate the ids lv
lvchange -an sd_uuid/ids
6. Activate the domain (via engine)
The domain should become active after a while.
