i see you do some of the things i do sometimes..
good to have a separate non-raided system disk...
- you can always restore and rebuild your system
in 5-15 minutes and be back online
- i would have made /usr /var /tmp non-raid'd too
( so that everything to be booted/running is non-raid
- raid can be finicky sometimes
/dev/hdax,y,z is standalong boot off hda
/dev/hdcx,y,z is a backup standalone boot off hdc
( or even better to have a spare 4GB disk for system
( ie system NOT on the same disks as raid'd data
/dev/hdayy + /dev/hdcyy is /dev/md0 for /home
good to have data ( /home ) to be raid'd
- raid1 is good -- for mirroring in case one disk dies
- raid0 is good if disk read are important
last option is to use completely raid'd system including /
- kinda risky in my book .. :-)
- if you can't build your raid devices, you lose
everything
i only care about "saving user data" ... system is easy to rebuild
and is backed up gazillion places on the net
