I am setting up a new system using ubunto server 10.10. I have 1
4TB level 1+0
raid array consisting of 4 2TB drives which will be the main os
drive and 1 2TB
level 0 raid array which will be the holding disk. Should I set this server
up using lvm and create 1 6TB volume or should I create two (1 4TB
and 1 2TB) lvm
volumes?
If I were you, I would definitely create two separate volumes. The
intended workloads, as well as underlying RAID setup, are rather
different. With two volumes, if one disk in your RAID0 dies, you lose
only the holdingdisk, which is probably survivable. With one volume,
you stand a good chance of losing the entire server which is not so
good.
