Yes, the permissions thing might be the show-stopper on this, but I have to get it to work first. And this is a Netapp vol, mounted at the vol level only once.

Couple of things - you need to do the mount at the netapp volume level. So the share has to be at the netapp volume level. mounting the volume at any other level will generate this error. - If you mount the same volume more than once at different locations/levels it can get confused and give this error. So make sure that there is only one mount under that volume. - when you backup a Netapp windows permission volume, backing it up over NFS will not capture more than standard unix permissions. In order to capture full windows permissions you need to backup the volume from a windows host or use NDMP. - I haven't tried backing up via cifs on linux but, after you get it working make sure you check the permissions are backed up and restored properly. - Make sure you setup the NAS user and password correctly see http://www.ibm.com/developerworks/wikis/display/tivolistoragemanager/Snapshot+Differencing+Caveats I created it to lessen the pain of others On 29/02/12 09:43, Paul Zarnowski wrote: > I would be happy to be proven wrong on this, but I believe that snapdiff for > CIFS is only supported on Windows. snapdiff for NFS is supported on AIX and > Linux. > > BTW, that particular error message seems to be issued for a variety of > reasons.
