got exactly the same issue, with all nice side effects like performance
degradation. Until now i was not able to fix this, or to fool the engine somehow
that it whould show the image as ok again and give me a 2nd chance to drop the
in some cases this procedure helped (needs 2nd storage domain)
-> image live migration to a different storage domain (check which combinations
are supported, iscsi -> nfs domain seems unsupported. iscsi -> iscsi works)
-> snapshot went into ok state, and in ~50% i was able to drop the snapshot
than. space had been reclaimed, so seems like this worked
other workaround is through exporting the image onto a nfs export domain, here
you can tell the engine to not export snapshots. after re-importing everything
the snapshot feature (live at least) should be avoided at all currently....
simply not reliable enaugh.
your way works, too. already did that, even it was a pita to figure out where to
find what. this symlinking mess between /rhev /dev and /var/lib/libvirt is
really awesome. not.
