unRaid 6.1 moved /root/mdcmd to /usr/local/sbin/mdcmd.

 

The preclear script still uses /root/mdcmd. I think this might mean that preclear will not detect whether user is trying to wipe a disk already in the array.

 

The old preclear thread seems to be closed: http://lime-technology.com/forum/index.php?topic=2817.0, I cannot reply on that thread, and the download link is still there, so that could be a problem people accidentally downloading that link.

 

A change like seems to work:

# unRaid 6.0.1 -> 6.1.2 moved mdcmd from /root/mdcmd to /usr/local/sbin/mdcmd
mdcmd_cmd=/usr/local/sbin/mdcmd
[[ ! -n $(type -P "$mdcmd_cmd") ]] && mdcmd_cmd=/root/mdcmd
devices=`$mdcmd_cmd status | strings | grep rdevName | sed 's/\([^=]*\)=\([^=]\)/\/dev\/\2/'` 

 

instead of this

 

devices=`/root/mdcmd status | strings | grep rdevName | sed 's/\([^=]*\)=\([^=]\)/\/dev\/\2/'`

as a temporary fix you could try this in the command prompt before you run preclear

 

ln /root/mdcmd /usr/local/sbin/mdcmd

Yeah, I've added that to my config/go-file as I expect there might be other scripts with similar problems. I have also searched my flash drive for 'mdcmd' and fixed all the /root/mdcmd references I found, but still some might be hidden inside archived files I expect.

 

Personally I've just fixed my copy of the preclear script, but that won't help others, hence this thread.
