Not sure what the testing came up with, but I figured out a way to get
it to work:
mkdir /dev/md
for array in /dev/md[0-9]* ; do
# subshell so the $MD_* variables don't carry between arrays
(
eval `mdadm --detail --export $array`
[ -z "$MD_NAME" ] && exit 0 # v0.9 metadata has no name
real_name=`echo "$MD_NAME" | cut -d: -f2`
# if there's no host field (no colon), use the full name
[ -z "$real_name" ] && real_name="$MD_NAME"
cp -a $array "/dev/md/$real_name"
cp -a $array "/dev/md_$real_name"
# might or might not be needed; my setup works without:
rm $array
)
done
I have not tested this on a metadata=0.9 array, but as long as those
don't provide an MD_NAME in --detail --export, it should work fine.
