All,
I'm conceptually putting together a NFS server in my head. (I will build it once I know what it is!!)
What I want is something flexible.
ie. Have it start with 3 or 4 drives, then add a drive when I need the capacity. Remove a drive when I don't. replace the drives with bigger drives as the become available. All without losing my data. (Or having to back it up / restore it.)
My first thought - LVM.
I'm very familiar with LVM. It does not really do the same things as RAID. Not even if you only worry about the performance side of things. ie. a 4 disk raid system is faster than a single disk for most raid setups. With LVM based on 4-drives, it is typically just the same speed as a single disk.
Completely agree, but I read your requirements above to be more to do with space management than performance. /Per -- /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
