extendfs

[Mike Burk]

How do I umount /var to extend it?

[James R. Ferguson]

Hi Mike:

I assume that you don't have Online JFS so therefore the way I've done it when I didn't, is to boot up into single user mode, where only the root directory is mounted, and do the necessary maintenance.

Single user mode at the console should do. You may still have to un-mount the /var volume first before extending the fs, but that is all.

In single user mode (reboot and from ipl hpux -is or from system shutdown 0) lvextend and extendfs.

If time is a factor, I type in init s
make the change and then init 3 to return. Then a reboot durring backup to make sure things are in proper order. Just be aware that this method doesn't kill all processes in the way that a reboot does. So I do this on delevopement systems rather than production.

Hi,

if you still have trouble to unmount the filesystem in single user mode run fuser -k on /var... that will kill all running processes on the filesystem.

Take care,
