Recovering from a two-drive failure in a RAID 10 configuration
In a RAID 10 configuration with four drives, data can be recovered if two of the drives fail. But recovering the data depends on which drives in the RAID configuration fail.
So it's possible to recover data if two drives in a RAID 10 configuration fail, but it's dependent upon which two drives fail. Consider a four-drive RAID 10 setup where drives A and B have data striped across them and are mirrored by drives C and D on the opposite side. This RAID group can recover if any or all drives in a stripe fail, but not if both drives in a particular mirror fail. Therefore, we can recover if drives A and B or drives C and D fail, but not if drives A and C or drives B and D fail.
