Re: [Question] RAID-0 with raidtools2
hi ya
i assume you are trying to make one big disk so that
you can have huge files 100GB-sized files
using four 40GB disks ??
- ie.. why do you use raid0 ???
if your /etc/raidtab...
- change nr-raid-disk to say 4 since you have
4 disks
- if any of the 4 disks dies... you lose all data...
------------------
if you wanna protect against disk failure...
- use raid5 with your 4 disks...
setup / /tmp /var /usr as raid1 mirroring so that
you can still boot off any disk even if one of um dies
save /home onto raid5 across all 4 drives... so that you
still protected against a single disk failure
----------------
raid is NOT a backup of important data...
- save that off to a different system
more fun raiding...
