it worked (kind of). Thanks.
I was able to recreate (the all appear in /proc/mdstat) and in the rescue I've mounted the /boot which maps to /dev/md0. But I can't mount any other partition.
they all complain with the same error
mount: Mounting /dev/mdX on /tmp/mountpoint failed: no such file or directory
Any ideas?

$ cat docs/sysadm/mdadm_recovery.txt
## define possible devices with arrays
echo 'DEVICE /dev/hd[a-l]* /dev/sd[a-l]*' > mdadm.conf
## scan
mdadm --examine --scan --config=mdadm.conf >> mdadm.conf
## review configuration, copy to /etc
cp mdadm.conf /etc/
## create devices
MAKEDEV md || { for ((i=0; i <= 31; i++)); do mknod /dev/md$i b 9 $i;
done; }
## start arrays
mdadm --assemble --scan
Best of luck,
