You have to boot into maintenance mode and select start a maintenance shell, unmount /tmp, remove /tmp, then recreate the logical volume and create a filesystem, change permissions, sync, reboot

You can also edit your image.data file and set rootvg filesystem sizes as desired - you will also need to edit the corresponing logical volume entry.

Do a mksysb (without re-creating this file) and then restore from this mksysb.

 

[Chapter11]

For an OS filesystem, you have to do the above tricks (restore from mksysb or maintenance mode). Those are / /usr /var /tmp and usually /home

Other filesystems generally do not have this limitation as they can usually be unmounted live. You have to use those above procedures because those filesystems *cannot* be unmounted on a running system.

just a question... but why do a mksysb restore for reducing /tmp? there is nothing to keep in it and that is a drastic step to take, and longer, than just recreating it?

 

[Chapter11]

Just my opinion, but for the unexperienced, I would bet that doing a mksysb would be easier than working in maintenance mode.
