expand /tmp /opt

If I have free extentes in vg00, but I dont have online JFS, can I still expand those filesystems(/tmp /opt) without using an ignite reorg? Can I use the usual commands and just unmount the filesystems before expansion?

These filesystems do not have to be contiguous, so you can increase them without using ignite. But you will find that /tmp is in use pretty much all the time, so I think you will have to be in single user mode to expand it.

I have to agree with Mark: the chances of unmounting either of these are slim and none. Single user mode is going to be required. Then you can just run your lvextend and extendfs - see the examples in the man pages.

Hi,

Booting in single user mode and using lvextend and extendfs will achive this. But before this just make sure that these are not marked contiguous, if marked change them with lvchange prior to extending.

HI,

I agree, you must use single user mode to increate /tmp when you don't have online JFS.
