On the DD:

nfs disable

I haven't tried this myself- I don't know what happens to any mounted
volumes.

Subject: [ADSM-L] Stopping access to a filepool

How do you offline/stop_access to a filepool?

We have been implementing a DataDomain which is accessed as a filepool.
Prior to the DD, most backups went to the diskpool with some very large
backups going straight to tape.  When we would want to take the library
down, we would kill any processes/sessions writing to tape and then
take the tape drives offline.  This prevented any new sessions from
trying to access tape until the library work was completed.

Now were trying to figure out that the equivalent process is for the DD
and it's filepool.

Most backups still go into the diskpool, and the very large backups
go straight into the DD filepool.  If we want to take the DD down for
some reason, we would kill any processes/sessions writing directly
to the filepool, but we can't think of any way to prevent new sessions
from trying to access the filepool.   I guess I'm looking for some way
to offline the filepool.

Any thought/comments are most welcome!

Rick
