hi philippe
since i am typing from memory...
if you have access to rh-7.1... try it...
- be sure you have selected "fd" type...NOT linux ( type 82 )
and i would NOT separate / and /boot
my standard partitions was/is...
name size ------- -- raid 1 ---------
----- ------
/ 96Mb /dev/hda1 /dev/hdb1 --> /dev/md0
/tmp 128Mb /dev/hda2 /dev/hdb2 --> /dev/md1
/var 512M /dev/hda3 /dev/hdb3 --> /dev/md2
/usr 4096M /dev/hda5 /dev/hdb5 --> /dev/md3
swap 512M /dev/hda6 /dev/hdb6 swap
/opt rest of disk /dev/hda7 /dev/hda7 --> /dev/md4
than try to connect/disconnect hda or hdb and see
if it still boots...
if one dirve fails...you should be able to boot from the other one
have fun
