Periodic Snapshot Task - dataset or zvol not found

[JoaoSilva]

Hello,

I'm trying to create a Periodic Snapshot Task for 2 zvol, and getting the same error on both. The error is "ZFS dataset or zvol not found".

This are 2 existing volumes with data that are currently in use. If create a new volume, I can create the task for it without issue.

The volumes were created in a previous version of TrueNas. Currently it running TrueNAS-13.0-U4.

Anyone has any ideias?

Thanks in advance,
João Silva
