In order to save data from a MBWE II, you only need to pay attention to the 4th Raid array. First and third are OS, second is swap. That is why these three are in Raid 1. The data can be in Raid 0 (linear) or Raid 1.
This thing's main board died and I'm not able to access the drives through the machine anymore. I put the drives (2x 500GB) in my own computer to retrieve the data, but the raid configuration is bizarre.
The drive was set up as 1TB (RAID0), but when I look at the actual drives in Linux, it shows this:
Device Boot Start End Blocks Id System
/dev/sda1 4 369 2939895 fd Linux raid autodetect
/dev/sda2 370 382 104422+ fd Linux raid autodetect
/dev/sda3 383 505 987997+ fd Linux raid autodetect
/dev/sda4 506 60801 484327620 fd Linux raid autodetect
Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00007c00
Device Boot Start End Blocks Id System
/dev/sdb1 4 369 2939895 fd Linux raid autodetect
/dev/sdb2 370 382 104422+ fd Linux raid autodetect
/dev/sdb3 383 505 987997+ fd Linux raid autodetect
/dev/sdb4 506 60801 484327620 fd Linux raid autodetect
When I do mdadm --examine on each partition, sda1 & sdb1 (first partitions) show no superblock, sda2 & sdb2 (second partitions) show RAID1, the third partitions show RAID1, and the fourth partitions show Linear.
I've tried everything I can think of to raid these partitions into a single drive, and nothing is working. Does anyone have any idea how to do this?
