mdcmd spindown / spinup explanation


Fire

Recommended Posts

Hello,

i set up my new unRAID rig and now i want to enable S3 Sleep. It works fine already, except the disks shown as spun-down after waking up from S3 even they are rotating. It seems to be a little bug in the unRAID routine/webinterface. Now i have to tell the unRAID OS that the drives are spinning. On the other thread i found a command

 

for disknum in 0 `ls /dev/md* | sed "sX/dev/mdXX"`; do /root/mdcmd spinup $disknum; done

 

which does that very well (i run it after wake up from S3) ... except parity2.

 

mdcmd spinup 0              <<-- spins up parity

mdcmd spinup 1              <<-- spins up data disk 1

etc

 

but what spins up parity2 and cache?
