Re: [linux-lvm] volume group setup question




i'm a LVM newbie trying to figure out how to setup volume groups on a new
Linux system. the underlying physical volume will be a hardware RAID5
disk. i'm thinking about having a non-LVM root partition and a logical
volume per each of the major mount points in the system (/usr, /home,
/tmp, /var etc.) but i'm having problems deciding whether to start with a
volume group per logical volume or just one volume group with all the
logical volumes in it?

You will have one vg for the physical storage and then split it into lv's for the mount points. The only reason for multiple vg's is multiple storage systems (e.g., storage blocks on an EMC or a standalone Storage Works unit) next to your machine.

is there any benefit from partitioning the RAID disk and having a separate

None whatsoever. vg's group pv's together; partition the space with lv's.
