Hi,
An unknown bug broke our gluster storage (dom_md/ids is corrupted) and oVirt
no longer activates the storage(I tried to recover it using the similar
issues reported in mailing list but it didn't work).
Can you explain what you did?
The best way to fix this is to initialize the corrupt id file and
activate the domain.
As I checked VM disk images are still accessible when I mount the
gluster
storage manually.
How can we manually move the VM disk images to local storage? (oVirt
complains about gluster storage being inactive when using the web interface
for move/copy)
You can easily copy the images to another file based storage (nfs,
gluster) like this:
1. activate other storage domain using engine
2. mount gluster domain manually
3. copy the image from gluster domain to the other domain:
cp -r gluster-domain-mountpoint/images/image-uuid
/rhev/data-center/mnt/server:_path/other-domain-uuid/images/
But the images will not be available since engine does know them.
Maybe this can be
fixed by modifying engine database.
Another solution (if you are using ovirt 4.0), is to upload the images
to a new disk,
and attach the disk to the vm instead of the missing disk.
