Hi all,
I've a 6 disk RAID6 array, with 1 missing disk. I moved 2 of the HDDs
from the on-board SATA controller to a LSI MegaRAID controller where I
created them as individual RAID0's. The data in the array isn't
important, but it'd be nice if I can reassemble it.
This is what it looks like:
$ for I in /dev/sd?;do sudo mdadm -E $I;done
