Hi guys,
Just de-powered, moved, and re-powered my NAS, and got this mail:
A DegradedArray event had been detected on md device /dev/md127.
Faithfully yours, etc.
P.S. The /proc/mdstat file currently contains the following:
Personalities : [raid6] [raid5] [raid4]
md127 : active raid5 sda[0] sdd[3] sdc[2]
5860538880 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/3] [U_UU]

And checking the state it says "clean,degraded", with the following info....
