I have a 5-disk RAID-5 array in an SBS 2008 server, and it's been working fine for > 12 months now, but today I logged in to find this in the disk management console:
Of the five-disk array, it seems to have doubled itself up.
- Array 1: Disk 1 & 5 are fine, Disk 2,3,4 are "Missing"
- Array 2: Disk 2,3,4 are Foreign, disks 1 & 5 are "Missing"
Disk 0 and 6 are seperate, non-RAID disks
I don't have physical access to the server, but I have some remote hands and they tell me that all the lights on the disk bays are on, so I very much doubt that all three disks have failed.
I'm too scared to import the foreign disks, because 2 of the 5 disks are missing from the set, I don't want it to destroy the data on the array (Yes, I have backups, but that's a huge hassle).
Any ideas what might have happened here, and how I can can "glue" the array back together? I've already removed each disk from the device manager and then scanned for new hardware in case that fixed it, but it didn't, and I can't think of where to go from here.
