Hi Michael,

unless you have adv journal filesystem installed (which you can check with swlist command) you need to bring the box down to single user mode to extend /tmp.

If you have online JFS:
#fsadm -F vxfs -b xxx /tmp
else boot in single user mode and
lvextend and extendfs

[John Bolene]

Any file system increase has to umount the file system to do commands on it.

/tmp is always in use in multiuser mode.

As Steffi said, take it to single user mode.

If you are trying to expand /root or /stand, about the only way is to reignite the box and specify it larger at that point.

Just to add something to vincenzo's post.

If you have Online JFS...first extend your lvol:

lvextend -l /dev/vg00/lvol_

Then extend your filesystem with the fsadm command as was mentioned above...NOTE that the amount should be in Kbytes (pe_amt x 4 x 1024 = kb)

Otherwise, follow the advice given to boot to single user and extend via tha 'regular' method.

find out if you have jfs "which fsadm" | swlist | grep JFS

anyway if you have it "fsadm -F vxfs -b <1024*lvsize> /tmp"

if not reboot, stop boot, boot pri isl, interact with isl=yes, hpux -is, then continue with the extending the file system.

First of all, if you have OnlineJFS installed then you don't need to unmount /tmp. Many (most) servers these days are ordered with OnlineJFS so I give you those instructions first.
From SAM:
Disks & Filesystems->Logical Volumes
Locate the logical volume for /tmp and highlight it.
Then Actions->Increase Size
Enter the new desired size and you're done.
It will grow the logical volume and the filesystem 'on the fly'.

Before you start the above procedure; cd to /tmp and make sure you have a lost+found directory; if not, create one. The filesystem
commands will fail otherwise.

Now, if you don't have OnlineJFS things are a little more complicated. Because /tmp is almost always in use you will probably have to go to single-user mode; if you boot in singl-user mode /tmp will not be mounted.

You can use lvextend to grow the logical volume and then extendfs to grow the filesystem.

man lvextend and extendfs. By the way, where's your SA - that bum should be doing this.
