I have two virtual disks sda and sdb on an rhel7 VM. My /var and /var/log folders are both constrained by the sizes of their initial provisioned logical volumes.
sda is partitioned into an xfs filesystem: /dev/sda1 mounted at /boot and a physical volume: /dev/sda2 named rhel.
There is a volume group: rhel with several logical volumes, specifically the ones of concern to this question are mounted at /var, /var/log, /var/log/audit/ and /var/tmp.
The disk sdb is new and I was thinking of creating a single pv/vg out of the drive and moving /var, /var/log and /var/log/audit/ (keeping /var/tmp on it's own lvm on sda2) to it.
- Would it just be better/possible to just grow the current logical volumes from space allocated from the new disk, if so, how does that work?
- Is there a good reason NOT to just have
/var,/var/logand/var/log/audit/on the same logical volume? - Is there a way to do this online, meaning this is a web server and I would like to have it continue serving?
- If this is unable to be done online, what steps would I need to take to reboot into a mode I can ssh into the server but no other services running that would prevent me from unmounting/moving the
/varfolder's contents?
