I'm in the process of setting up a new Linux server, so I have no production data on it yet, and nothing installed or running on it yet other than the O/S. This is Oracle's "Enterprise Linux 4" (same as RedHat 4AS). I chose "LVM" during the install and remembered to set up separate partitions for: /home, /opt, /tmp and /usr (plus the default partitions for /boot and /swap) then left the balance of the RAID1 local SCSI disk (about 70GB) for: /var. But, I should have set up two more separate partitions of 8GB each and left /var somewhat smaller.
I'm assuming there must be a way to resize /var smaller under LVM and create to new partitions in that space without having to do a complete O/S re-install, right? At this point an O/S re-install would only waste about 3 hours of my time, and there would be no data loss, but I'm trying to avoid the waste of time and learn some more about what's possible in Linux too. I may be an expert in Oracle but I have no UNIX experience and only limited Linux experience.
What are my options? Is there a relatively easy way to make my (ext3) /var partition smaller?
