increase /opt

[Ratzie]

We needed to increase the /opt partition. It would not let us unmount the disk.

What would be the correct procedures?

Boot into single user mode. Re-boot the machine, interrupt at the 10 second prompt, enter "hpus -is" and the machine will come up in single user mode with nothing but / mounted. I normally do a mount -a at that point so I can access all the commands and stuff I need. Then unmount /opt, lvextend and extendfs.

1. Goto single user mode.
2. extennd the LV for opt.
3. Extend the fs

If you have Online JFS, no need to go to single user mode, just LVextend and fsadm

If you don't have online JFS, You have to go in single user mode and then extend lvol6.
In this case:
-reboot
-interact with IPL
-Boot with tool "HPUX -is"
-You are in single user mode.
-Extend lvol6
-Reboot.

That's all.

You could also do a :

fuser -cu /opt

See what processes are there - if you can - kill them, then unmount it, lvextend, extendfs it.

Otherwise, single user mode as above, or if you have online JFS:

lvextend -L /vgXX/lvolX

fsadm -b M /opt

Hi,

It would be worth nothing the space available in the VG.
Plan for the application/s outage. Then it is good idea to go for single user mode otherwise stop all applications ,might be init 2.
then fuser -u /opt
fuser -ku /dev/vg00/lvolx
umount /opt
lvdisplay /dev/vg00/lvolx | egrep "Allocated|Size"
Add to it the PE's you will be allocating.
then
lvextend -l|L | /dev/vg00/lvolx
fsadm -b -r .
Hope this helps

Hi

You can logon to single user mode ,extend the logical volume for /opt and extend the filesystem ,mount it back & check.Online JFS will be helpful to extend without unmounting /opt.
