Extending /tmp partition on 11.23 ia64 Itanium server

[sharathkv25]

Hello,

I would like to extend the /tmp partition on B.11.23 ia64 Itanium server. I am not able to do so. This is the log:

Basically there are still processes that are using that filesystem. You would have to use lsof to find them and see if you can kill them.

Do you have OnlineJFS?

[sharathkv25]

No, I don't have OnlineJFS installed.

Take a look at some of these threads about extending root with ignite:

Ignite to extend /tmp, Dennis?


Reboot your server, allow the system to boot from the default boot entry and hit any key to stop the hp-ux loader.

Press Any Key to interrupt Autoboot
\EFI\HPUX\AUTO ==> boot vmunix -lq
Seconds left till autoboot - 10
Type 'help' for help


go to single user mode from there:

HPUX> boot vmunix -is

Activate vg00.
Now you can perform your
lvextend
and
extendfs
on the lvol.

[Sagar Sirdesai]

Hi Sharath.

If you have space in vg00.
You extend the lvol4 using lvextend command and then use fsadm command to extend the Filesystem .

For fsadm to work you need Online JFS installed on you server..
lvextend -L M /dev/vg00/lvol4
fsadm -F vxfs -b M /tmp

Hope this help

See the link, scroll down to

Extending a Logical Volume When You Canâ t Use SAM

http://docs.hp.com/en/B2355-90950/ch09s01.html

Dear

stop any running service on the server oracle any other thing or just reboot the server that it will kill all processes then try to unmount /tmp partition then increase the size or just use sam to increase /tmp size

If you have free space in vg00 and can reboot the server just create one new logical volume with desired size, edit fstab to mount it as /tmp after reboot and reboot.
