I've been reading the RHEL 5 manual/guide linked from centos, and the
idea of LVM with expandable partitions seems like a great idea (yes
duh why else would it exist if not?). Although the documentation shows
a screenshot of how the final setup would look like with LVM & RAID
together, it doesn't actually gives the step.
1. Am I correct in thinking it should be done in this way
- setup Softraid
- setup LVM on the raid partitions
Secondly, LVM allows expansion of the LVM group when we add a new
drive. But with softraid, how will this happen? Searching around does
not turn up any guide on this. Am I correct in thinking I must always
add new drives in pairs (for Raid 1), create a new softraid partition
then assign this new partition to the LVM group?
yup, pretty much thats how it works.
In IBM AIX (where LVM kinda came from), the soft raid and volume
management is rather tightly integrated, but in linux, its seperate.
