unable to shutdown array to restart server after repairing array. *fixed*

Trying to restart the server to get docker back up and working again. When attempting to shutdown the array i get this error constantly while the array is trying to shutdown:

Sep 17 00:01:04 Tower root: rmdir: failed to remove '/mnt/user': Directory not empty

Sep 17 00:01:04 Tower emhttpd: shcmd (1757): exit status: 1

Sep 17 00:01:04 Tower emhttpd: shcmd (1759): rm -f /boot/config/plugins/dynamix/mover.cron

Sep 17 00:01:04 Tower emhttpd: shcmd (1760): /usr/local/sbin/update_cron

Sep 17 00:01:05 Tower emhttpd: Retry unmounting user share(s)...

Sep 17 00:01:10 Tower emhttpd: shcmd (1761): /usr/sbin/zfs unmount -a

Sep 17 00:01:10 Tower emhttpd: shcmd (1762): umount /mnt/user

Sep 17 00:01:10 Tower root: umount: /mnt/user: not mounted.

Sep 17 00:01:10 Tower emhttpd: shcmd (1762): exit status: 32

Sep 17 00:01:10 Tower emhttpd: shcmd (1763): rmdir /mnt/user

Sep 17 00:01:10 Tower root: rmdir: failed to remove '/mnt/user': Directory not empty

Checked if there were any ssh or terminal sessions open, none that i can tell, and no scripts running, and no open file transfers or open processes for smb/nfs (checked with lsof /mnt/user - no return in terminal via web)

Before this issue, I had a disk starting to fail and was constantly erroring due to bad sectors. I shutdown the array and moved over a "fresh" disk from my unassigned devices and replaced disk 9 on the array. restarted the array which began the Parity rebuild of disk 9. After this started docker refused to run and gave this error:

Sep 16 04:32:46 Tower emhttpd: error: malloc_share_locations, 8160: Operation not supported (95): getxattr: /mnt/user/appdata

Sep 16 04:32:46 Tower emhttpd: error: malloc_share_locations, 8160: Operation not supported (95): getxattr: /mnt/user/data

just continuous error up till the rebuild finished. and my docker app location changed from /mnt/user/appdata/Docker to /mnt/cache/appdata/Docker/

Just alot of weird issues and i wanted to restart the server to see if that helped clear up any of the oddities in order to get docker working again (I miss Plex).

-****Well I fixed the issue by just force restarting the server and then enabling my user scripts after reinstalling my Docker apps. everything back up and working***
