Hi,

With OnlineJFS

Extend logical volume
# lvextend -L xxx /dev/vg00/lvolxx

Extend fileystem
# fsadm -F vxfs -b xxxM /opt

Not OnlineJFS

# lvextend -L xxx /dev/vg00/lvolxx
# extendfs -F vxfs /dev/vgxx/rlvolx

Hi,

Not OnlineJFS

# lvextend -L xxx /dev/vg00/lvolxx

Before you extend the Filesystem you must umount it

# extendfs -F vxfs /dev/vgxx/rlvolx

Mount the Filesystem

# swlist -l product OnlineJFS

Should display something like:
OnlineJFS B.11.11 Online features of the VxFS File System

Hi,

swlist -l fileset |grep OnlineJFS
# OnlineJFS01 4.1.008 Online features of the VxFS File System
OnlineJFS01.VXFS41-AD-RN 4.1.004 Utilities for JFS management

This is the fast mode.

practically you should extend the FS after extending a LV, else you will not be able to use the whole spce in LV to store files
