1) extend the logical volume:

/usr/sbin/lvextend -L /dev/vgxx/lvolyy

2) extend the file system

lvextend -L /dev/vgXX/lvolyy

As you have OnlineJFS no umount of the file system is needed

Rainer

Using /home (/dev/vg00/lvol8)on a VXFS filesystem as an example, extending to 800Mb using Online JFS

lvextend -L 800 /dev/vg00/lvol8
fsadm -F vxfs -b 819200 /home

Hi say you want to extend /var on /dev/vg00/lvol7 from 1000 to 2000 Gb:

lvextend -L 2000 /dev/vg00/lvol7
fsadm -F vxfs -b 2048000 /var

The argument for lvextend is Mb; for fsadm it is Kb.

Hi

Something come out I just found that I have only 300MB of free space, How can I reduce the other logical volume.

Joseph

Hi Joseph,

The principle is the same but I would make a backup of a filesystem before you reduce the size.

Hi Joseph,
are the 300 mb what you have left in the volume group? If the logical volume is mirrored, you also have to take that into account. Check:
# lvdisplay -v | more

Is the line "Mirror copies" 1=mirrored or 0=not mirrored?

regards,
John K.
