Evidence of deleted dataset still remains

I have TN13.0U3.1 and it has one pool, BackupPool

On another machine (same version) I made and ran three replications (via GUI) to replicate three datastores (each under BackupPool, not recursive). So on the target I have BackupPool/Set1, BackupPool/Set2 and BackupPool/Set3. No problem there.

Then I deleted one of the three replications (for Set3) and deleted the corresponding datastore from the target (all via GUI). Again, no problem.

So when I go to the shell (via GUI), I do an “ls /mnt/BackupPool” and /mnt/BackupPool/Set3 still shows up! It does not appear in the GUI under pools.

I rebooted just in case. Still there.

What gives?


That’s probably the dataset mountpoint (an empty directory).

That said, there will always be evidence of deleted datasets as long as the pool exists. Dataset-related operations are written into the immutable zpool history log.
