so close yet so far or maybe that's just the way it is, I am dumb on it
but gettin smarter.
the 2 ide drives diff channels of course hda and hdc each w/3 partitions
hda1 2 3 hdc1 2 3.
I format hot add sda1 2 3
cat /proc/mdstat it's all there
...# mdadm /dev/md0 1 2 -f /dev/hdc1 2 3 (fail or fault hdc
md automatically picks up sda from spare status and writes to it.
it finishes mind you hdc is still under fail status and I reboot.
when the sys comes back up, it does not pick up sda anymore but instead
just runs -U on all 3 partitions
I was under the impression that sda would be there either I missed a
step somewhere or something strange going on
