Re: is my raid1 array really working??
it worked w/ the /tmp mount. i verified by
writing/deleting files to the mounted /dev/md4 /tmp
device and then mounting /dev/hdc8 /mnt/hdc5 and
taking a look.
after writing /dev/md4 /tmp to fstab, i used mount -a
and it worked.
i'll try the /home partition next ... it was late so i
stopped there lest i zigged when i should have zagged.
