Increasing /

hp-ux 10.20

I need to increase the "/" partition, which is /dev/vg00/lvol3.

I understand it needs to be contiguous, so how do I handle it?

First of all, make sure there are no large files "by accident" in root.

In best way is to do an ignite backup and adjust the size while restoring.

problem with large files and such is that when I run "find" or "du", it's going into other filesystems.

du -sk *|sort -rn

would usually do the trick, but not here.

Anyway, you say Ignite is my best option?

Hi:

Yes, the root filesystem must be contiguous.

The simplest way to achieve its expansion is to re-Ignite your server.

# make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

Then, boot from this tape. Choose the Media Only option and an Advanced Installation mode. You can resize your filesytems to your tastes as necessary.

Unfortunately there is no easy way to extend /.

You will have to reinstall the OS.

Take an ignite backup of the system, and perform an interactive ignite restore. This will allow you to modify the size of /, and it will restore the system to the state it was in at the time of the ignite backup i.e. patches, users, passwords and so forth.

Hi (again):

To restrict 'du' to the root filesystem, add the '-x' switch:

# du -kx /|sort -k1nr
