Hi list! Having experienced firsthand the pain that hardware RAID controllers can be -- my 3ware 7500-8 died and it took me a week to find even a 7508-8 -- I would like to switch to kernel software RAID. Here's a tentative setup: Intel SE7230NH1-E mainboard Pentium D 930 2x1GB Crucial 533 DDR2 ECC Intel SC5295-E enclosure Promise Ultra133 TX2 (2ch PATA) - 2x Maxtor 6B300R0 (300GB, DiamondMax 10) in RAID1 Onboard Intel ICH7R (4ch SATA) - 4x Western Digital WD5000YS (500GB, Caviar RE2) in RAID5 * Does this hardware work flawlessly with Linux? * Is it advisable to boot from the mirror? Would the box still boot with only one of the disks?
Let me say this about firmware mirror: while virtually every BIOS will boot the "next" disk if the first fails, some will not fail over if the first drive is returning a parity but still returning data. Take that data any way you want, drive failure at power cycle is somewhat more likely than failure while running.
* Can I use EVMS as a frontend? Does it even use md or is EVMS's RAID something else entirely? * Should I use the 300s as a single mirror, or span multiple ones over the two disks? * Am I even correct in assuming that I could stick an array in another box and have it work?
