That would be an oops!. You have valid raid arrays running somehow(?)
yet you are only writing and reading to one drive in the arrray. In
short, you have no true raid.
Here's my fstab. Note that only my /boot is directly on a raid array
all by itself. Everything else is on LVM.
# /etc/fstab: static file system information.

# <file system> <mount point> <type> <options> <dump><pass>
proc /proc proc defaults 0 0
/dev/mapper/mirror-root / ext3 defaults,errors=remount-ro 0 1
/dev/md0 /boot ext3 defaults 0 2
/dev/mapper/cat-home /home ext3 defaults 0 2
/dev/mapper/mirror-srv /srv ext3 defaults 0 2

Hopefully, someone here who has tried to fix your problem can give you
definitive advice. In its absence, here are my thoughts only:
You don't know if /dev/hd(b?)1 mataches /dev/hda1. Similarily, and for
testing a whole lot safer, you don't know if /dev/hdb8 matches /dev/hda8
(/tmp). Put a test file in /tmp. Mount /dev/hdb8 on /mnt and see if
the file is there. I would hazard a guess that it is not.
If not, try this:
unmount /dev/hdb8.
remove /dev/hdb8 from the array (fail it, so that the array is
degraded).
add /dev/hdb8 in again and watch it sync.
remout /dev/hdb8 on /mnt and see if it is there.
If so:
unmount both /dev/hdb8 and /dev/hda8
edit /etc/fstab to point to the correct md array
remont /tmp
see if you have a functioning /tmp.
If this works, then you have a strategy to attempt from single-user
mode. If not, you'll have to think of something else. At least these
are raid1 arrays.
Good luck.
Doug.
