Now we are attempting to upgrade it to latest version, 4.4.2, but it fails as shown below. Problem is that the Storage domains listed are all located on an external iSCSI SAN. The Storage Domains were created in another cluster we had (oVirt Node 4.3 based) and detached from the old cluster and imported successfully into the new cluster through the oVirt Management interface. As I understand, oVirt itself has created the mount points under /rhev/data-center/mnt/blockSD/ for each of the iSCSI domains, and as such they are not really storaged domains on the / filesystem. > > > > I do believe the solution to the mentioned BugZilla bug has caused a new bug, but I may be wrong. I cannot see what we have done wrong when importing these storage domains to the cluster (well, actually, some were freshly created in this cluster, thus fully managed by oVirt 4.4 manager interface). > > This is likely caused by the fix for: > https://bugzilla.redhat.com/show_bug.cgi?id=1850378 . > > Adding Nir. > > > > > What can we do to proceed in upgrading the hosts to latest oVirt Node? > > Right now, without another fix?

Nir - is it safe, in this case, to remove these dead symlinks? Or even all of /rhev/data-center/mnt/blockSD/* ? Will VDSM re-create them upon return from maintenance?

Any other workaround?
