I am using unraid 6.8.3

When clicking stop array, the status is stuck at Array Stopping Retry unmounting user share(s)...

there are two issues.

  1. /mnt/user cannot be unmounted by the system. I have to manually do fusermount -uz /mnt/user
  2. The script left an empty folder in /mnt/user0/mount_rclone. The system cannot delete it automatically and thus failed to umount /mnt/user0 as it is not empty.

Please see the log below

Having the same issue. Did you figure out a resolution?

I was having the same problem, found a script that southloven posted over on the unraid forums and customized it for my use.

Run "lsof | grep /mnt/user/ " when the array is stuck unmounting disks and customize the script for your needs.

#!/bin/bash

Same issue here. Confirmed fixed by @thegreenemachine55's suggestion.

I've updated the the unmount script to use the share location variables used in the rclone_mount script and will issue a pull request this weekend.
