When you say "not visible in oVirt" you mean that you do not see them in the UI?

Yes, I can see some VM with prefix "external-" and without disks.

Do you know the specific uuids for the missing volumes? You could use lvm to check if the LVs are visible to the host.

lvs --config 'global {use_lvmetad=0}' -o +tags

For each LV, the tag beginning with IU_ indicates the image the volume belongs to.

If the wanted images are present on the host but not in engine then you had a problem with import. If the images are not visible to the host then you probably have some storage connection issue.

This disks are presented in oVirt and VM works OK.

Another disks with ERROR code are fully corrupted?

Please advise, where I can find some materials how oVirt (or maybe VDSM) works with block storage, multipath?

Hi, community!

After import DATA DOMAIN some VM disks not visible in oVirt.
Can I manually copy VM disks from data domain at FC block device?
