2 weeks ago our backup filer started refused to create a snapvault relationship for a new volume with this error message:

so we went ahead and ordered a new shelf to extend the aggregate on filer2. This has been delivered today and I see the free space.
But ..., our production filer kept on growing (this volume hosts a LUN used by MS Exchange). We are running quite tight on storage on filer1 as well so we have been deleting snapshots on that volume on filer1. Now when I try to run an auxiliary copy, it hangs on the 'pending' state.
I have noticed that the snapshots snapprotect creates during the primary classic have as dependency 'none whereas other snapprotect backups that are working have a dependency 'snapvault'. In the snapvault list I see the exchange volumes are no longer listed, so it looks like the snapvault relationship has been deleted.
If it's a new volume added to the relationship that has never baselined you can adjust the threshold from 80% to 85%(that would put you just above the 84.29%) to allow the replication to continue until you had more storage (on the secondary).
Depending on which snapshots were deleted corresponding jobs may need to be "not picked" so that the Auxcopy process does not try to copy them anymore.
Relationships don't get deleted, but it would be best to investigate further with a technical support case. In a scenario like this, the full sendlogs, DFMDC and Autosupports from the primary and secondary nodes will be needed.
