Right, so 56 days after the massive failure I have another degraded RAID on my hands. This time I didn’t get any emails to tell me about it. Not sure why, I’ll assume the email part is my fault to give Thecus the benefit of the doubt…
I happened to load up the admin website for the device as I’ve gotten into the habit of doing and noticed the Array was degraded. I took a look at the disks and drive 5 was missing. Strange… I took a look at the logs and it showed the array going into a degraded mode but no mention of the drive falling off of the face of the earth. I went down to the basement to take a look at it but the drive looked fine. When I pulled it out of the N5200 it wasn’t spinning but when I slid it back in it spun up just fine.
I logged into the device over SSH and, using mdadm, adding the drive back into the array. The array rebuilt over a couple of hours and 4 days later it’s still running fine, no disk errors and no array problems.
What happened? Why did the disk stop working? At this point I’m tempted to believe it’s the fault of the N5200 and not the drive. Data was fine of course but I’m one step closer to getting rid of this thing…
