March 26, 20215 yr When I stop the array, almost all the time I'll end up in a loop trying to unmount /mnt/user. I've looked through various posts where people have the same problem, and haven't been able to figure this out. Running 'lsof /mnt/user' in the console outputs nothing. I do use rclone and mergerfs - which I thought might be the culprit. However, even when I reboot, and don't run the rclone/mergerfs, I still get the problem. I'm attaching the diagnostic file. Thanks. Quote Mar 26 13:49:01 Tower emhttpd: Stopping File Activity... Mar 26 13:49:03 Tower Recycle Bin: Stopping Recycle Bin Mar 26 13:49:03 Tower emhttpd: Stopping Recycle Bin...

March 26, 20215 yr Author I've found my problem. It WAS a mergerfs mount that I was not explicitly unmounting prior to stopping the array. I found it with the following command: mount | grep /mnt/user .. Once found I was able to 'umount /mnt/user/[name of mountpoint]' and the stop array was able to continue.
