My Drobo v2 recently began constantly going through relayout, but I’ve noticed that it alerts me with a relayout messages occasionally followed by a disk failure, then it goes intore layout again.
I powered it off and it came up all green, then a while later the second from the bottom disk went red, then shortly thereafter it went into relayout again.
I’m thinking that maybe the drobo thinks it’s lost drive 3, then can see it again and starts rebuilding parity. This is on a Drobo v2 with 4x2TB WD20EARS. I’ve order yet another 2TB WD20EARS and was planning to replacing drive 3, but thought I’d post here to see if others see this as reasonable - or if I missed something.
It sure would be nice if Drobo’s alert would mention the slot # of the drive that failed. It would also be nice if Drobo would give you plain logs and didn’t encrypt your diagnostic information.
The single logical volume is configured as 16 TB, and there should be over 800 GB free on the LV.
