Provisioning Manager vFiler migrate fails - then disables snapmirror killing other operations

fletch2007 — Thu, 05 Jun 2025 07:05:38 GMT

Hi, Provisioning Manager is being used to migrated several vFilers, but this one is repeatedly failing - can someone decipher why?

Another issue is when this failure occurs, it disables snapmirror on the head - killing other migrations and snapmirrors! (I end up having to issue an options snapmirror.enable on)

Here is the excerpt from the vfiler_trans_migrate_log – can you tell me why the cutover of app-vf-01 repeatedly fails and why it sets options snapmirror.enable off causing all other snapmirrors to abort ?

thanks

Hi, with netapp support's help, we determined there was a stale /etc/sm/notify entry preventing the offlining of the old volume.

cp /dev/null /etc/sm/notify resolved this

thanks
