Redhat LVM backup / restore issues?
I am planning the deployment of a new server running RHEL4 u4. The server will have a 2 drive HW Raid1 volume (where i will be installing the OS) and then a 4 drive HW raid5 volume (for my data). I normally don't use logical volume manager but if it actually works as advertised, then it may be beneficial for me to setup the raid 5 volume as an lvm just in case i ever need to expand. I have 2 questions about this:
1) how easy / difficult is it to expand an LVM?
2) are their any backup / restore concerns for using an LVM? I usually use cpio for my linux backups and restores.
any input would help me....thanks in advance.
