We have a vendor installing a product on a zLinux image. This product uses MySQL, which defaults to placing its databases on /var (which I consider a Bad Idea, but that's beside the point). Because of this, they need 80 GB for /var. I have an 80 GB ext3 file system created in LVM and mounted, but they need that space in /var, which currently only has one 3390-3. Is there a way to move /var onto the LVM file system? The last time I tried something like this, it resulted in a reload of the OS.
It's easy.
Shut down to single user mode (telinit S).
mount /dev/lvmwhatever /mnt
cp -a /var/* /mnt
umount /mnt umount /var
mount /dev/lvmwhatever /var
edit /etc/fstab to find /var on /dev/lvmwhatever
telinit 3 (or whatever the default runlevel is)
