Hi, I have a snapshot_for_backup which snap list reports as "busy" but it's not. There's no backups currently running. However, when I try to delete this snapshot I get "Snapshot in use by dump or a CIFS share." I've confirmed that dump is not running, nor are any of the cifs sessions touching it. How can I get rid of this snapshot? My snap reserve is about to get dangerously full.
Thanks,
-Leigh

What does "backup status" show? You may have a "restartable" dump from some time ago. If that's the problem, "backup terminate [number]" will release the snapshot.

Snapshots held busy by restartable backups are supposed to be deleted automatically if the snapshot usage goes over 100% of the reserve. That's what the documentation says: I haven't tested it for real.
If that's not the problem, then you may have a bug. There have been such in the past: e.g. 31340 (present in 5.3.x and early 6.0.x / 6.1.x). Rebooting _might_ get rid of the problem in that case, but you should talk to NetApp support first.

When a dump is aborted and becomes restartable, we keep the snapshot but the busy flag is cleared out of it. This snapshot most likely does not belong to a restartable dump. On the other hand, "backup status" would have an entry for it if the a dump is actively running. Otherwise, it could be a runaway busy snapshot.

Leigh,
If you cannot reboot the filer, there is an unsupported way to free the snapshot. ndmpd is probably holding the snap even if ndmpd status shows nothing.
You can run the advanced "ps" command and kill ndmpd. If you're not comfortable doing this, I don't blame you. Just reboot the filer :)
Here are some details:

Hi toasters,
we got a costumer running several Mac OS X machines and having a Win2K native domain inside wich a Filer is registerd.
I would like to know if there is any known way to enable Mac OS X machines to connect to the Filer as a casual CIFS clients (being able make profit of the Windows user's particularity as home dir and so on). I know Mac OS X use a core samba layer to access CIFS ressources but I don't know how to configure it - if it possible - to join a Win2K domain (the one here is a native one, but if it is mandatory that tha mode being mixte, it would be okay too).
Fanx a lot in advance :o)
There are (at least) a couple ways you can get to yoru filer -- First, if you have NFS enabled, since Mac OSX is unix under the covers, you can NFS mount volumes as needed.
Next, you can go to the Mac OS Finder and from the "Go" menu, select "connect to server" and then type in:
cifs://your_filer_here/sharename/
I've been using both methods for a while and they seem to work, no problem.

Even better... You can attach to smb://username@filer/sharename via the same mechanism. This should bring up an authentication panel that will allow you to enter the domain name and password for the user in that domain.

I bet your filer is in a windows workgroup (?) what if the filer is in a windows domain (win2k native). I know there is a way to call a share with smbmout (or pretty the same with mount -t smb) :
smbmount //fjall/test /data/test -o username=tridge,password=foobar //fjall/test /data/test mount -t smbfs -o username=tridge,password=foobar //fjall/test /data/test
when trying what you advice from the costumer Mac OS X, we get some cifs.trace_login output as follow (forget about the error code, I didn't well note it) : << [CIFSAuthen]: Login attempt by WORKGROUP\tridge from GENGHIS [CIFSAuthen]: ...error 0000XX... ...
Some kind of password miss-encrypted i think (not encrypted, it works well in workgroup, but in domai it should be encrypted)...
fanku again

Supposedly it's no problem, but you have to be at a certain level of ONTAP.
From: http://now.netapp.com/Knowledgebase/solutionarea.asp?id=ntapcs8691&resource= you need to be at ONTAP version 6.2.2 at a minimum.
We'll be upgrading next weekend and will know first-hand as of then.
