I seem to be having the same issue as some others but I've tried stopping the docker and it hasn't worked.

 

root@Tower:~# umount /var/lib/docker
umount: /var/lib/docker: not mounted.

 

 

root@Tower:~# losetup
NAME       SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE             DIO LOG-SEC

This worked:

 

This looks like it worked.  Thank you.  Anybody else seeing this i used these command lines in terminal where DiskX = disk that is caught in unmounting loop under the log (in my case disk2)

 

dd if=/dev/zero of=diskX bs=1M count=310

 

mkfs -t xfs diskX

 

mount diskX /mnt/diskX

 

Now I can't add a new drive to the array but that seems to be a different issue.
