Also written Sun, 08 Nov 2015 20:06:00 GMT. Either sdc or sde is your first disk. The other is parity, which is the last disk on the first stripe, with zeros in the matching offsets of the other two disks. > 04975030 22 e0 84 41 68 0b 2a 3e 53 ef fa 4d ab cf 92 78 |"..Ah.*>S..M...x| > 04d09830 09 96 1e 05 dd 53 70 02 53 ef c8 99 81 bb db 08 |.....Sp.S.......| > 07554c30 ad fb d5 76 b9 04 8b ab 53 ef 6d 9e 7d 92 61 2b |...v....S.m.}.a+| > 08100030 7c 6b 49 55 12 00 19 00 53 ef 00 00 01 20 76 ed ||kIU....S.... v.| Another possible backup superblock, written Wed, 06 May 2015 01:16:44 GMT.

We know the possible order combinations: sdc1 sdb1 sdd1 sde1 sdc1 sdd1 sdb1 sde1 sde1 sdb1 sdd1 sdc1 sde1 sdd1 sdb1 sdc1 We don't know the chunk size for sure. I don't remember when the default changed from 64 to 512. I'd try 64 first. It's possible you could map the standard locations of ext4 superblocks versus the locations noted above, and work out the order and chunk size. I'll leave that as an exercise for you, if you don't want to just try the various combinations. :-) Remember, "fsck -n" after each --create --assume-clean to see if it works well.
