Need to extend / (root)

Christopher Blad — Tue, 02 Nov 2004 14:55:22 GMT

Hello all,

This may be a ridiculous question to pose to all of you but I'm new to HP-UX administration and I wanted to get the best advice available which is all of you.

It has been decided that the "/" volume on our HP-UX 11.23 system needs to be extended. Obviously, this cannot be accomplished through lvextend through "conventional" means since it cannot be unmounted per se.

My question is....what is the best process by which "/" can be extended.

Thank you all ahead of time.

Regards,
Christopher Blad

With a make_recovery tape.

Basically, you create the tape, boot it, from recovery mode, resize your root partitions, then recover vg00...

for the root partition, your best best is to reignite the system

In addition to no unmounting, the / needs to be a contiguous space.

Hi Christopher,

Root "/" has to be contiguous and since the filesystem structure is already laid out on the disk, you cannot extend the size of "/" without reinstallation. One want to do the reinstallation is taking a ignite backup and then doing a reinstall using the ignite backup. Take 2 to be on the safer side.

The other choice is do a fresh install where you can define the new sizes, if it is possible to do a fresh install.

To learn more about ignite, checkout the ignite faq / documentation at this link,

Hope this helps.

Thanks to all three of you...especially for the detailed information.

We'll start working on the ignite backup and recovery straight away.

Thanks again.
