Hello, Some mistakes in what you wrote.

RAID 10 is also immune to single disk failure but uses > half the disks for parity. RAID 1 and 10 are just mirrors, they have no parity. I guess you mean "redundancy". RAID 5 does not use data disks and parity disks. Data and parity are distributed among all disks in the array. RAID 1 with N disks can survive N-1 disk failures. > If you are concerned about availability, with 4 disks (the simplest RAID > 10 configuration) Linux can use a special RAID 10 mode (mirror+stripe) with two or three disks. > with 6 disks, RAID 6 will give you double the capacity of 4 disks > or get you immunity to 3 disks failing. RAID 6 can survive 2 disk failures regarless of the number of disks in the array. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
