Ok, so hearing all the excitement I ran a check on a multi-disk
RAID-1. One of the RAID-1 disks failed out, maybe by coincidence
but presumably due to the check. (I also have another disk in
the array deliberately removed as a backup mechanism.) And
of course there is a big mismatch count.
Questions: will repair do the right thing for multidisk RAID-1, e.g.
vote or something? Do I need a special version of mdadm to
do this safely? What am I forgetting to ask?
