Re: extending logical volume
more information like
# vgdisplay -v /dev/vg_name -> if you can post output
and which file system or logical volume you want to extend -> output we advice accordingly
# bdf /file_system_1 ..2 ..3 ..4

Solution(1)Check whether you are having free space in your VG ( PE size * Free PE)
(2)Check who is accessing the LV using
#fuser ├в cu /mount point
(3)Unmount the LV
#umount lv_name
#kill ├в 9 pid if device is busy
(4)Extending LV
# lvextend ├в L final_size /dev/vg/lvname
(5)Extending FS
#extendfs ├в F
(6)mount /mount_point
Above steps you can follow if you donot have online JFS
(7) With OnlineJFS you do not need to umount. Use fsadm instead:
# fsadm -b
(8)Each logical volume having limitation of logical extent i.e 655535 , beyond this you can not extend the LV.
Hopes this will help you to extend LV.

Subodh.
