Hi David,

It's the same procedure as

With OnLine JFS this is easy. But one should ask themselves a BIG question "Why does /tmp need to be increased? Does it need cleaned up or is something/someone using it incorrectly?"

We set our /tmp up for 256MB & never have to increase it. We use *other* areas for user & app scratch areas. /tmp should NOT be having large files placed in it - that's *not* what it's for.

My 2 cents,
Jeff

Generally speaking, you are going to have to go to single user mode first and make sure you don't mount /tmp. If you have any probelms with this and I have seen people finding it difficult, comment out the /tmp entry in /etc/fstab before going single user. That way it can't be mounted.

use mount command to show file system and logical volume info lvol6 is default for /tmp


lvextend -L 512 /dev/vg00/lvol6
extendfs -L 512 /dev/vg00/lvol6

512 MB total new size or whatever size you wish

David,

You shouldn't really need all that much space in /tmp. Maybe we should look into what's filling it up before we start enlarging it?

I am obviously assuming you don't have OnlineJfs!

I once had a machine with a command before "mount" to read a file in / and if the file had a filesystem in it to run "extendfs". This meant that extending a filesystem when you didn't have onlineJFS and couldn't unmount the fileystem in multiuser mode was simply a re-boot. This works becuase you CAN increase the logical volume size online if you have online JFS or not.

an alternate method depending on your system is to make an ignite image then restore it specifying a bigger /tmp detailed instructions available if this an option for you.

David my syntax is wrong on teh extendfs earlier it should have an r for raw device

extendfs -L 512 /dev/vg00/rlvol6

David,

Run "du -sk /tmp/* |sort -n" and let's see what's taking up all the room.

To add to the Pete's suggestion you can also make use of "lsof" to see if any of the open files are occupying the space.
