Re: raid 1 recovery
hi ya
you only have "data" mirrored as raid1
if either hda or hdc dies.. you wil NOT be able to
keep running
hda1 must also be "fd filesystem" type in fdisk
that is why you are having so much trouble
when you disconnect hda1 or hdc1
-- you do NOT have the "linux distro" installed as raid1
( just mirroring of user data /home )
all partitions are "fd" type
/ should be /dev/md0 == hda1 + hdc1
/tmp should be /dev/md1 == hda2 + hdc2
/var should be /dev/md2 == hda3 + hdc3
/usr should be /dev/md3 == hda5 + hdc5
/home should be /dev/md4 == hda6 + hdc6
-- if you are paranoid, and have an older bios..
you'd probably want /boot too but newer bios dont have
those 1024clylinder boot problems
- stick swap in there too
- though i dont see any point to mirroring swap...
-- now you have what you were orinally looking for..
- boot off of hda1 or /dev/hdc1
