Your raid array seems to have two failed devices: slot 2 and slot 7.
I think I know why mdctl didn't pick this up. I'll try to find time
to sort it out...
I would suggest that you
mdctl --create /dev/md0 -l 5 -n 9 -p left_asymmetric -c 256 \
/dev/sdi1 /dev/sdf1 missing /dev/sda1 /dev/sdd1 /dev/sde1 \
/dev/sdg1 /dev/sdb1 /dev/sdc1
and then
mdctl --add /dev/md0 /dev/sdh1
That should re-create the array and preserve any data that is on it.
However, these is a suggesting that /dev/sdb had some sort of error.
You should look in the kernel logs to find out more
about it.
