Re: [ovirt-users] Storage domain not in pool issue
Hi Adam,
Thank you to take your precious time to my problem.
First of all, I want to precise that I don't want to recreate new VMs, but to recover
them in the 2 Storage domains, I don't have any backups of them.
So I don't just want to re-active the domains, I'd prefer a non destructive
solution.
Regards
Alain

Hi,
Is there any news ??
I there anybody who can help me ?
This long silence get me more and more worried.
I saw that Federico Simoncelli is working on a new feature "StoragePool Metadata
Removal", but I don't have any advice from him or anybody else.
I'd be really happy to know if somebody works on this kind of problem, I guess that
I'm not the only one with this issue, and potentially this can be a disaster bug that
could be a bad thing for the reputation of the oVirt platform.
Don't forget that my Data Center is out of order since March 13th, and this is not
trustable for a production environment.
Let me know what you think about it ?
Hi,
Yesterday I tried to reproduce your situation with a local oVirt setup I have. I then
tried to manually alter the metadata to force detach the storage domain from the old pool.
My steps involved the use of the vgchange command to remove and add VG tags to the volume
group that holds the storage domain. Unfortunately I was not successful in reviving the
domain. I'm trying to find some help for you since I think I have reached my limit
for this situation.
How familiar are you with LVM? If you can activate the VG for your storage domain and
then activate all of its LVs, you may be able to scrape the disks off of the storage using
the qemu-img command. If you place those disks on an export domain then you could import
them into your working storage domain and use them to recreate new VMs.
This is a clunky and labor intensive solution but could work if we are unable to revive
the domain in its entirety.
Let me know if you'd like to pursue this approach.
