As a side note, I don't use RAID 5 anymore, period. While RAID 10 is wasteful, a double disk failure normally doesn't take it out. That's not true for RAID5. ATA drives have gotten so crappy that I have had drive failures during the process of rebuilding from a drive failure. Maybe we need a RAID 55 which provides resilience against 2 drive failures ... In addition, full RAID 10 provides a very nice method for creating backups. Shut down the system, pull one half the drives, put in all new drives, and rebuild the array. Voila! Instant backup (and instant recovery, if required). -a To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
