TrueNAS 12.0-U6.1
2 TrueNAS servers - a primary and a backup server which I am trying to replicate a zvol to. The zvol is shared out with iSCSI to a cluster and the space used as reported by the cluster software is 246GB.
Please note I have used 80% of the pool space for the zvol. I know (from other posts on here :)) that I should use 50% max of the pool for the zvol) but this is a test environment and will never be used in production.
Primary -
Backup -
the backup server zvol has nothing it in at present, it is a new pool and zvol.
Can anyone help me understand why when I try to replicate it says it cannot snapshot as it is out of space and there seems to be more than enough space to copy the data across together with a snapshot.
Any pointers much appreciated
