It looks like you encounter a problem to mount the storage domain.
Can u please try to mount the storage domain manually from the Host server

Bug tickets must have version flags set prior to targeting them to a release. Please ask maintainer to set the correct version flags and only then set the target milestone.

I tried it, and it fails with the same error. Seems to be an environment issue. I'm investigating to make sure it is not engine-related in any way, but don't seems to be.

Got it working, the NFS daemons in the engine machine were in bad state. Feel free to close
