Hoping those with greater IT skills than I can advise if this is what it appears to be:
I just had the following e-mailed message via OMV:
This is an automatically generated mail message from mdadm running on openmediavault
A Fail event had been detected on md device /dev/md/0.
It could be related to component device /dev/sdd.
Faithfully yours, etc.
P.S. The /proc/mdstat file currently contains the following:
Personalities : [raid6] [raid5] [raid4] [linear] [multipath] [raid0] [raid1] [raid10]
md0 : active raid5 sdb sdd(F) sdc sde
8790405120 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/3] [UU_U]
unused devices: <none>Hi all
Looking under SMART and devices shows that sdd appears offline.
At the moment I can still access files on the server, but I'm pretty sure the RAID setup I have can only cope with one failed drive so I need to sort this before another falls over.
Anything worth trying before I assume it's dead?
Is there a walkthrough guide for replacing the drive and other steps to integrate a new drive into the RAID?
Many thanks for any and all advice
