Hi all,I know this isn't strictly Debian related, but I'll be implementing this on a Sarge system so I thought it appropriate.
I've just taken the plunge and bought 4 250GB SATA hard drives and am planning on implementing a RAID, with LVM2 layered over the top of that. The main purpose of this system will be to store films, music, and other general fileserver uses: in other words larger files as opposed to smaller ones. I've had a few ideas about how to set it all up, but I'm wondering what others would suggest...
Option 1: RAID 10
md0: RAID 1 (sda sdc)
md1: RAID 1 (sdb sdd)
md2: RAID 0 (md0 md1)
Option 2: RAID 0+1
md0: RAID 0 (sda sdc)
md1: RAID 0 (sdb sdd)
md2: RAID 1 (md0 md1)
Option 3: RAID 5
md0: RAID 5 (sda sdb sdc sdd)
Option 4: 2xRAID 0 + LVM striping
md0: RAID 0 (sda sdc)
md1: RAID 0 (sdb sdd)
Striping would be implemented through LVM.
In particular I'm having trouble figuring out what the actual
performance / fault-tolerance differences between RAID 10 and RAID 0
+1 might be. I hear RAID 5 is hardly worth using in software, and I'm
not sure I'd be using it properly with only 4 drives. As for the
final option, would there be any advantage at all to using this
method (bearing in mind I'll be using LVM in any case)? Would anyone
have any other suggestions?
