Subject: [PATCH] storage: Handle failure from refreshVol
|
|
|
|
Commit id '155ca616' added the 'refreshVol' API. In an NFS root-squash
|
|
environment it was possible that if the just created volume from XML wasn't
|
|
properly created with the right uid/gid and/or mode, then the followup
|
|
refreshVol will fail to open the volume in order to get the allocation/
|
|
capacity values. This would leave the volume still on the server and
|
|
cause a libvirtd crash because 'voldef' would be in the pool list, but
|
|
the cleanup code would free it.
|
|
|
|
(cherry picked from commit db9277a39bc364806e8d3e08a08fc128d59b7094)
