Re: [ADSM-L] SNAPDIFF with CIFS on Linux supported?

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

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.
We have found it hard to figure out what the problem is at times, and we have
an open PMR for this message right now.

What's in the can...
Obviously, Linux systems can mount CIFS shares, but does anyone have the
SNAPDIFF option working? I keep getting:
"ANS2831E Incremental by snapshot difference cannot be performed on /mountpoint as
is is not a NetApp NFS or CIFS volume."
It is too! The message kind of implies that CIFS is OK on Linux.
