But the best way is to stop using RAID > and run a sheep daemon on for each disk. What happens if one of the disks dies? Can the daemon responsible for this disk deal with that and can I hot-plug a new disk an easily tell the daemon to treat it as such? This would make such a "one daemon per disk" setup superior to a raid-0 setup as only a smaller chunk of data would disappear when a disk dies. Regards, Dennis |
