Earlier today I received an automated email from mdadm monitor with the following:

A Fail event had been detected on md device /dev/md127.
It could be related to component device /dev/sdd1.
Faithfully yours, etc.
P.S. The /proc/mdstat file currently contains the following:
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md127 : active raid10 sda1[0] sdc1[2] sdd1[3](F) sdb1[1]
5860267008 blocks super 1.2 512K chunks 2 near-copies [4/3] [UUU_]
[==========>..........] check = 50.9% (2983082496/5860267008) finish=1025.1min speed=46774K/sec
unused devices: <none>
I just logged into the server and ran cat /proc/mdstat
and this is the result:
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md127 : active raid10 sda1[0] sdb1[1] sdc1[2]
5860267008 blocks super 1.2 512K chunks 2 near-copies [4/3] [UUU_]
unused devices: <none>
Did I understand this right? Has a drive failed?
