Sorry guys, I know this is very off-track for this list, but google hasn't been of much help. This is my raid array on which my PG data resides.
I have a 4 disk Raid10 array running on linux MD raid. Sda / sdb / sdc / sdd One fine day, 2 of the drives just suddenly decide to die on me. (sda and sdd) I've tried multiple methods to try to determine if I can get them back online. 1) replace sda w/ fresh drive and resync - Failed 2) replace sdd w/ fresh drive and resync - Failed 3) replace sda w/ fresh drive but keeping existing sdd and resync - Failed 4) replace sdd w/ fresh drive but keeping existing sda and resync - Failed Raid10 is supposed to be able to withstand up to 2 drive failures if the failures are from different sides of the mirror. Right now, I'm not sure which drive belongs to which. How do I determine that? Does it depend on the output of /prod/mdstat and in that order?
