There is an unsupported java shell you can invoke and kill the ndmp sessions. Even though ndmpd says no active sessions, it probably has some snapshots locked.

filer> java netapp.cmds.jsh jsh> ps <grab thread names for ndmpd sessions> jsh> kill threadName jsh> exit filer> snap delete vol0 snapshot-name

Greetings, First time caller.

I have a 520 for which "snap list" returns several snapshot_for_backup ( busy ) lines. These are old and for some reason were not deleted automatically. I cannot delete them manually either.

I have tried setting "snap sched vol0 0 0 0" turned "vol options vol0 nosnap on" and was still unable to delete the snapshots.

Below is the output of snap list.

Any suggestions on how to get rid of the unwanted snapshots would be appreciated.
