Hi, you can use lvextend to extend the logical volume. Then you would need to extend the file system. If your system has online JFS then you can use fsadm -b Otherwise you would need to unmount /home and use extendfs.

I have online JFS. So the process of extending a normal LVM is same as that of a mirrored LVM?

Yes... And if you have doubts, then use sam to do the job..
You can then look at the logs generated by sam to see how it was done...

Is the LV for /home all you want to do? Or do you want to create a mirrored boot disk?
