Break off Snapmirror from non-existing filer

gesturgis — Thu, 05 Jun 2025 06:26:06 GMT

Hey folks,

snapmirror status shows an old snapmirror relationship where the source is the current filer and the destination is some old, long gone filer.

How can I delete this orphaned relationship?

Thanks.

We had some other posts on this... the 2 usual suspects are either 1) an entry in /etc/snapmirror.conf that you need to delete or 2) an old snapmirror snapshot on the volume (snap list volname to see). If neither of those then it is an orphan in the registry...there is a kb article on cleaning it up but requires some downtime on the node and should be done with support on the phone. Check the first 2, then if neither of those open a support case and one of the engineers can webex or talk you through it quickly.

Run snapmirror status to the list of old relationships
Run snapmirror release on each relationship

If that doesn't work you could use this approach:

Run a snap list on all the volumes on your system to find volumes with snapshots suffixed with "(snapmirror)"
Look for entries that that have the host name of your old, long gone Filer
Use snap delete to delete this snapmirror snapshots
