[Users] local storage problems

I'm trying to play with engine and vdsm on the same machine, but I can't add a local storage. This is the last error from vdsm: 7e6c31db-abc0-4d6c-baff-d78e9c47d7a2::ERROR::2012-10-23 10:22:02,454::task::833::TaskManager.Task::(_setError) Task=`7e6c31db-abc0-4d6c-baff-d78e9c47d7a2`::Unexpected error Traceback (most recent call last): File "/usr/share/vdsm/storage/task.py", line 840, in _run return fn(*args, **kargs) File "/usr/share/vdsm/storage/task.py", line 307, in run return self.cmd(*self.argslist, **self.argsdict) File "/usr/share/vdsm/storage/sp.py", line 269, in startSpm self._upgradePool(expectedDomVersion, __securityOverride=True) File "/usr/share/vdsm/storage/securable.py", line 68, in wrapper return f(self, *args, **kwargs) File "/usr/share/vdsm/storage/sp.py", line 409, in _upgradePool self._convertDomain(self.masterDomain, str(targetDomVersion)) File "/usr/share/vdsm/storage/sp.py", line 1027, in _convertDomain domain.getRealDomain(), isMsd, targetFormat) File "/usr/share/vdsm/storage/imageRepository/formatConverter.py", line 252, in convert converter(repoPath, hostId, imageRepo, isMsd) File "/usr/share/vdsm/storage/imageRepository/formatConverter.py", line 99, in v3DomainConverter newClusterLock.acquireHostId(hostId, async=False) File "/usr/share/vdsm/storage/safelease.py", line 175, in acquireHostId raise se.AcquireHostIdFailure(self._sdUUID, e) AcquireHostIdFailure: Cannot acquire host id: ('a6d7a944-4807-474d-89b0-df9e74dd2cd0', SanlockException(19, 'Sanlock lockspace add failure', 'No such device')) If I make the DC a NFS one, I can add nfs paths.
