I received this rather nice email today suggesting one of the drives in a RAID1 array has failed.
A Fail event had been detected on md device /dev/md4. It could be related to component device /dev/sdc2. Faithfully yours, etc. P.S. The /proc/mdstat file currently contains the following: Personalities : [raid1] md4 : active raid1 sdd2 sdc2(F) 87667136 blocks [2/1] [_U] md3 : active raid1 sdd1 sdc1 250304 blocks [2/2] [UU]
The strange thing is that sdc2 is just one partition and the other partition has not failed.
Since the server in another country, I can't physically inspect it. Any suggestions as to how to test whether this is really a failure or a glitch?
