I have a SUPERMICRO SuperServer 5017R-MTF server with 4 Western Digital WDE SATA drives in it. This was setup in the BIOS as a RAID10 Array then OpenSUSE dropped on it. It appears one of the drives is off line now. Here is the good part, like the BIOS RAID thing is not enough. This is a single volume and it also boots off of it. What can I do to repair this? Some info is below. Please let me know what else is needed. Thanks! # cat /proc/mdstat Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md125 : inactive sdc[0](S) 1105 blocks super external:imsm md126 : active raid10 sda[2] sdb[1] sdd[0] 3711641600 blocks super external:/md127/0 64K chunks 2 near-copies [4/3] [UU_U] [=============>.......] resync = 68.7% (2550717632/3711641856) finish=157.5min speed=122779K/sec md127 : inactive sda[2](S) sdd[1](S) sdb[0](S) 9459 blocks super external:imsm unused devices: # mdadm --version mdadm - v3.3 - 3rd September 2013 # mdadm --detail /dev/md126 /dev/md126: Container : /dev/md/RAID_0, member 0 Raid Level : raid10 Array Size : 3711641600 (3539.70 GiB 3800.72 GB) Used Dev Size : 1855820928 (1769.85 GiB 1900.36 GB) Raid Devices : 4 Total Devices : 3 State : active, degraded, resyncing Active Devices : 3 Working Devices : 3 Failed Devices : 0 Spare Devices : 0 Layout : near=2 Chunk Size : 64K Resync Status : 69% complete UUID : dd2ab43b:37dd6ee2:8d78e0a9:ba8c4eec Number Major Minor RaidDevice State 2 8 0 0 active sync set-A /dev/sda 1 8 16 1 active sync set-B /dev/sdb 4 0 0 4 removed 0 8 48 3 active sync set-B /dev/sdd
