The mount is making unraid unable to stop array

[rqi14]

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?

[thegreenemachine55]

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.

[thekiefs]

Same problem here. Can this #30 please get merged?

[NineBall8]

@BinsonBuzz Works fine here, should we merge?

[Sildenafil99]

I have the same problem.
I used the script, and also added "umount -l /mnt/user0/" but now i stucked in
rmdir: failed to remove '/mnt/user0': Directory not empty
and
rmdir: failed to remove '/mnt/user': Directory not empty
