Replication Errors

[ZiggyGT]

I am trying to replicate a pool2 to pool3 on the same system. I set up the task to replicate pool2 to Pool3. It starts to run and then gives this error. Originally Pool3 was a samba share but I deleted that the first time I got the error. Pool2 is a samba share. Pool2 is my photo storage and I want to back it up to Pool3. In the background. What is the error code trying to tell me? What is samba4? Why is it busy.

Task State​

Error​

cannot unmount '/var/db/system/samba4': pool or dataset is busy
warning: cannot send 'pool2@auto-2022-11-06_19-10': signal received.

samba4 is just the version of samba (SMB) I think. This problem is in your system dataset. If it were me, and noone could tell me how to fix it straight up, I would try working around it by relocating the system dataset onto the boot pool. System > System Dataset. Then your replication might go.

I created pool4 on another system and was able to move pool2 to it as expected. I am going to move that data to pool3 and then redo the Pool2 dataset and move Pool3 to Pool2. It is an indirect route but I don't want to mess with Pool2 as it has key data. When you go to the doctor and say "Doc, It hurts when I do this", Doctor responds "Don't do that"
