Replication/unmount/deleting datasets errors

[edisondotme]

I've been doing some tests with replication tasks recently and I think things got messed up somehow.
Here's is what I did:

• Tried replicating block storage dataset to file system dataset. It failed (as it should) but when when I tried to go back and change the source destination dataset, my destination dataset was apparently missing. I believe it has something to do with [this](https://www.truenas.com/community/threads/replication-causing-datasets-to-act-unmounted.38410/). [This](https://www.truenas.com/community/threads/replication-causing-datasets-to-act-unmounted.38410/post-249537) reply says the bug was resolved, but I'm still having issues with it in 2021 apparently.
• Not knowing what was happening at the time, I just tried to remake the dataset with the same name (which worked) and I created a new source dataset that was a filesystem and not block storage. I edited the replication task with the new source dataset, re-ran, but got the error: `cannot unmount '/mnt/pool0/ds0/destination-dataset': unmount failed.`

• So then after some more searching and reading I thought it might be because the dataset was in use from an SMB share or something. So then I went to go delete the SMB share temporarily, but discovered that it was already gone.
• Weirdly, when I try to access the share on my local machine, it [still works](https://www.truenas.com/community/threads/deleted-smb-shares-still-mapping-in-windows.84923/) like normal even though it doesn't show up in the list of shares in TrueNAS. Ghost share
• Then I just tried to delete the dataset and start over, but I would get errors when trying to unmount. It won't let me.

Which of my actions have led to these symptoms?
Should I submit a bug report?
