[ale] recovering a software raid setup

[Greg Freemyer]

Never mind, I've got it.


fyi:

#mdadm --assemble -v --scan

went off and did a bunch of stuff.

Then

# cat /proc/mdstat

showed me the arrays is created.

It showed the /dev/sda5, /dev/sdb5 mirror was broken for some reason
and created 2 degraded arrays.  One for each half of the mirror.

But /dev/sdc3, /dev/sdd3 was fine.

And it took the degraded mirror for /dev/sdb5 and stripped it with the
sdc3/sdd3 mirror.

I now have that mounted and can see the filesystem.

Thanks
Greg
