Hi All,

I don't know if this is a Bug or an error on my side.

At the moment,  i have a oVirt 3.6 installation with two Nodes and Two
Storage Server, which
are configured themselfs als master/slave (solaris zfs snapshot copy
from master to slave all 2 hours)

Now i try to do some tests for some failure use cases like, master
storage isn't available anymore or
one of the virtual machines must be restored from the snapshot.

Because the data n the slave is a snapshot copy, all data which are on
the Data Domain NFS Storage,
are also on the slave NFS Storage.

I tried it to add over WebUI over the option "Import Domain" (Import
Pre-Configured Domain) with both
Domain Functions (Data and Export) but nothing happens, expect some
errors in the vdsm.log Logfile.

Something like this

11:44:41,758::hsm::2549::Storage.HSM::(disconnectStorageServer) Could
not disconnect from storageServer
Traceback (most recent call last):
  File "/usr/share/vdsm/storage/hsm.py", line 2545, in

    self._mount.umount(True, True)
  File "/usr/share/vdsm/storage/mount.py", line 256, in umount
    return self._runcmd(cmd, timeout)

    raise MountError(rc, ";".join((out, err)))
MountError: (32, ';umount:
mountpoint not found\n')

I checked with nfs-check.py if all permissions are ok, the tool say this:

Konsole output
[root@lin-ovirt1 contrib]# python ./nfs-check.py

Trying to /bin/mount -t nfs
