Hi again, I don’t know if it will be possible to import the storage domain due to conflicts with the UUID of the LVM devices. I’ve tried to issue a vgimportclone to chance the UUIDs and import the volume but it still does not shows up on oVirt.

I don’t know how to mount the iSCSI volume to recover the data. The data is there but it’s extremely difficult to get it.

Any ideias?

Thanks.
