/opt dir

[Sandile]

Hi all
Do I need to boot the server on the single user mode if I want to increase the size ?

[Alex Glennie · Accepted solution]

certainly do then run lvextend -L ### followed by an extendfs : both man pages have good eg's syntax.

ps unless you have on-line jfs installed ?

As long as you don't have OnlineJFS installed you need to umount /opt.

If nothing is busy on /opt you won't need single user.

Try umount'ing /opt. If OK then extend lvol and FS.
If umount says 'Device Busy' you could try to find the busy application on /opt (use fuser)

Shut down (if possible) every identified application using /opt and you are fine.
Otherwise single user is required.

Hi,

If you have Online-Jfs you don't need to stop anything.

If not, depending on the file system you want to increase size.

For data FS, you have to stop all proceses and then increase.

For OS FS, you need to boot in single user. Remember root FS. /opt is one of these.

Use the commands sugested by Alex.

HTH, Vicente.
