Extending /USR

Bona_1 — Mon, 11 Apr 2005 15:09:37 GMT

Hi all,
I have tried and tried and tried, no dice. Is it at all possible to extend the /usr filesystem? I don't seem to be able to unmount it at all. Please advise.

I believe that unless you have OnlineJFS installed for those filesystems, you have to increase /usr /var / from single-user mode.

Single user mode method

boot from console

intervene at the 10 second prompt

bo pri

Y Interact

hpux -is

I kernel loads, you get a prompt

lvextend -L /dev/vg00/lvol4 /dev/dsk/c1t1d1

choose a real vg name and disk.

extendfs -F vxfs /dev/vg00/rlvol4

shutdown -ry now

Hi Bona,

Yes above is correct, if you do not have online JFS you will have to boot into single user mode .

# shutdown -h -y now
reset the server

Interupt the boot process by holding any key (older systems may require the escape key, or break key)

at the boot prompt type
>boot pri

The system should ask then if you want to interacet with ISL. Type
>y

at the ISL prompt, type
>hpux -is

# /sbin/lvextend -L XXX /dev/vg00/lvolx
# /sbin/extendfs /dev/vg00/rlvolx

# mount -a
# bdf
# shutdown -r -y now

Hope this helps,
Robert-Jan
