I have a server that has a raid card with 2 channels. channel 1 is mirrored, raid 1. Channel 2 is raid 5 with 4 drives.
2 of the drives failed in the raid 5 and ofcourse shut down the raid.
I have 2 drives on the way for replacement but I wanted to know.
I can force 1 of the drives online and it comes back up, when I try to force the second one to rebuild it fails again.
but if I force 1 online will that be enough to get things running again? I can replace the 4th drive and rebuild.
I wasn't sure what would happen if I force the 3rd drive online if the raid would start to work after a reboot.
and for replacing the drives. what would be the best pratice for replacing 2 drives? just replace them both, force them online and rebuild?
