Adding space to /opt

[Larry Scheetz]

This might be a stupid one but here goes. I am used to using Online JFS with 11.00 I have a machine with no Online JFS and want to add space that is available to the /opt. Do I need to go into a single user mode to umount /opt and then add and then boot back into regular run level? Thank you for your help.

Yes, that is the easiest way.

Make sure that you actually reboot, interrupt the boot process, do an 'hpux -is' to get to single-user mode.

Just doing an 'init 1' may leave some processes running that still access /opt.

Unless you have OnlineJFS then you have to do it by your method. You may very well have to knock down and boot single user depending on what processes are actually running. You will have to first extend the LVOL and then the filesystem.

Hi Larry:

You might be able to unmount '/opt' to extend the filesystem. This is easier than dealing with '/usr' and '/var'. You can use 'fuser' to find and kill processes using '/opt'. These will include Measureware, etc.

Otherwise, I suggest you boot into single-user mode; 'lvextend' and 'extendfs' appropriately; and either reboot or do 'init 3' (or to whatever constitutes your default run-level).

Regards!

Hi

I would go to single user and then increase

You can do this from your desktop

shutdown -y 0

lvextend -L /dev/vg0#/lvol#

extendfs -F vxfs /dev/vg0#/rlvol#

reboot

Hi

If you want to install one large application in opt and dont have enough space it can be easier to create a new logical volume for this application and mount this volume on (for example) /opt/largeapp.

Always when you don't have online JFS, go to single user mode and do these type of tasks. It will be more convenient and easy. Take a make_recovery tape and good full backup before making any changes. Once extended, do a fsck on the file system and make sure that everything is alright.
