My goal was to migrate my "AppData" share off of my "Apps" pool to the array, upgrade the drives in the pool, then migrate back.

I stopped all my containers, turned off the Docker service and got the data from the pool to the array using Mover. Then, not thinking clearly (or, clearly not thinking), I started up the Docker service so that "everything would be running for the evening" (though slowly since the containers were living on the array, not fast SSDs), with the plan to pick up the next day with the physical drive replacements. This didn't go well.

When I started the Docker service, it created all the container directories on my Apps pool and when I went into my container's web UIs, nothing was configured - everything was in a default state.

I immediately shut down all the containers and the Docker service. I then reconfigured the AppData share to live on the Apps pool and ran the mover again to move everything back to the way it was to begin with. Unfortunately, when I started up the service & containers again, everything was still in a default, unconfigured state.

Is there any way for me to get back to where I was without having to manually reconfigure everything?

Appdata still has files on the array. Note that the mover won't move duplicates. Enable mover logging run the mover, and check the log, if some files are not moved because there are duplicates, you will need to delete one of the copies, typically the one on the pool, which should be newer.

Yes. Yes it does.

Once I get these moved over to the pool, everything should be restored to the way it was?

Is there any reason that I couldn't use MidnightCommander to manually move the /mnt/disk3/appdata/.. files to /mnt/apps/appdata/.. ?

I understand the difference between moving files between user shares and disk shares and the grave danger of attempting to mix the streams.

To answer my own question, no, there isn't a problem with this.

This has repaired all my containers (that I've checked so far), other than HomeAssistant, and that's something that seems to be much deeper than what can be fixed by a simple restore. Working with the HA folks on this.

Thanks @JorgeB !
