Seems like unmenu is missing /root/mdcmd too
Aug 12 21:54:38 NAS unmenu[4852]: sh: /root/mdcmd: No such file or directory
Aug 12 21:54:39 NAS unmenu[4852]: sh: /root/mdcmd: No such file or directory
Unmenu now reports the following under Array Status
Not started, unRAID ARRAY is STOPPED 0 disks in array. Array is not protected by a parity disk: Parity disk not configured.
