Bug Description


please have a look at:

I have Manila Xena with ONTAP 9.10 back end and set netapp:split_clone_on_create to "True".
What happened: a share was created from a snapshot, clone split was ongoing. A snapshot of this share had been created and delete of this snapshot went into above error. All happened within 15 minutes (part of a CI/CD) after share create, clone split was still ongoing.

So the fallback to deferred deletion would not work, because even a simple rename of the snapshot is blocked on the NetApp backend during clone split (busy volume).

Maybe the split job needs to be paused and resumed during this rename? Or the deferred deletion needs another marker, maybe the comment field can be modified or a tag being set?


And please see the related issue
