[ovirt-users] NFS

Dear all, We recently added 2 hypervisors to the domain on ovirt, but for some reason they can't connect to the nfs share: When I manually try to mount the nfs-share ([root@ovirthyp01dev ~]# mount -vvv -t nfs -o vers=3,tcp progress:/media/NfsProgress /rhev/data-center/mnt/ progress.brusselsairport.aero\:_media_NfsProgress/) : mount: external mount: argv[3] = "-v" mount: external mount: argv[4] = "-o" mount: external mount: argv[5] = "rw,vers=3,tcp" mount.nfs: timeout set for Tue Dec 16 08:56:47 2014 mount.nfs: trying text-based options 'vers=3,tcp,addr=10.110.56.20' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: portmap query failed: RPC: Program not registered mount.nfs: requested NFS version or transport protocol is not supported Thread-277::ERROR::2014-12-16 08:46:32,504::storageServer::211::Storage.StorageServer.MountConnection::(connect) Mount failed: (32, ';mount.nfs: requested NFS version or transport protocol is not supported\n') Traceback (most recent call last): File "/usr/share/vdsm/storage/storageServer.py", line 209, in connect self._mount.mount(self.options, self._vfsType) File "/usr/share/vdsm/storage/mount.py", line 223, in mount return self._runcmd(cmd, timeout) File "/usr/share/vdsm/storage/mount.py", line 239, in _runcmd raise MountError(rc, ";".join((out, err))) MountError: (32, ';mount.nfs: requested NFS version or transport protocol is not supported\n') Thread-277::ERROR::2014-12-16 08:46:32,508::hsm::2433::Storage.HSM::(connectStorageServer) Could not connect to storageServer Traceback (most recent call last): File "/usr/share/vdsm/storage/hsm.py", line 2430, in connectStorageServer conObj.connect() File "/usr/share/vdsm/storage/storageServer.py", line 328, in connect return self._mountCon.connect() File "/usr/share/vdsm/storage/storageServer.py", line 217, in connect raise e MountError: (32, ';mount.nfs: requested NFS version or transport protocol is not supported\n') Any ideas? The rest (4 others) didn't have any problems...
