I have a snapshot_for_backup which snap list reports as "busy" but it's not. There's no backups currently running.
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.
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.
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.
