In order to use the new encryption method in TrueNAS 12 I copied all data from a legacy encrypted FreeNAS pool to a newly foomatted pool via a replication task.
After replication there seems to be almost a GiB missing on the target pool:
Source pool after replication:
8.06 TiB used, 733.91 GiB available
Target pool after replication:
7.24 TiB used, 1.56 TiB available
For replication I used these settings (basic mode):
- source/target “On this System”
- left “Recursive” and “Replicate Custom Snapshots” unchecked (because I didn’t use snapshots)
- left “Encryption” unchecked
- Replication Schedule: Run Once
- unchecked “Make Destiation Dataset Read-only”
- Destination Snapshot Life Time: Same as Source
To find out what is missing a diff would take too long.
I tried but there was no output.
What else could I do to check for the missing files on the target in reasonable time? Is there something ZFS-related that might take up space and hasn’t been copied over by the replication task? What could that be?

I tried
Code:
rsync -avun --delete $TARGET $SOURCE | grep "^deleting "
