Re: /tmp & /opt extending
You basically have to boot into single user mode, init -s won't work.

Re: /tmp & /opt extending
Even without OnlineJFS this is pretty simple.
You just need to umount the file system and run extendfs
Problem is /tmp is usually pretty busy, and you will need to arrange a downtime. You need not go to single user mode, it would be enough to merely shut down applications that use /tmp
Of course single user or lvm maintenance mode does make all of this easier, but you have to sit through a reboot.

Re: /tmp & /opt extending
Once there, umount /tmp & /opt # Kill any process that is still accessing and extend the filesystem - procedure has been explained already. After this reboot the system.

Re: /tmp & /opt extending
fuser -cu /tmp --- To check the process accessing File system
Use
fuser -ku /tmp --- To kill the process.
