Hi,
ok, I admit I have not looked closely at drives and file systems for a while, my box has been running for some years and survived all the OMV migrations/updates I put up for it.
Since my drives are now >6 years old I thought about activating automatic notifications especially for SMART events, which I did yesterday. Tonight I got a mail "A DegradedArray event had been detected on md device /dev/md/126_0"
Looking at the GUI I'm not sure what to make of this, it says md125 is degraded (not 126)??
Can you shed some light on what these partitions really are and whether the "degraded" warning is something to worry about?
Best regards
Mark.
System looks like this:
Code
Personalities : [raid1] [raid6] [raid5] [raid4] [linear] [multipath] [raid0] [raid10]
md124 : active (auto-read-only) raid1 sdd1[0]
530048 blocks [1/1] [U]
bitmap: 0/65 pages [0KB], 4KB chunk
md125 : active (auto-read-only) raid1 sdd2[0]
530048 blocks [2/1] [U_]
md126 : active (auto-read-only) raid1 sdd4[0]
458880 blocks [1/1] [U]
bitmap: 0/57 pages [0KB], 4KB chunk
md127 : active raid5 sdb[1] sdc[2] sda[0]
5860530176 blocks super 1.2 level 5, 512k chunk, algorithm 2 [3/3] [UUU]
