expanding lvol

[Mazen Al-Jarrah]

Gentlemen;


How can I expand a lvol without going to single user mode...?


Thx

lvextend -L 2000 /dev/vg01/lvol1

This will extend the logical volume to 2GB.

If you have online JFS you can then increase the filesystem too with "fsadm -b 200M /my/mount/point"

If you don't have onlinejfs then you'll have to unmount the file system and go

extendfs -F vxfs /dev/vg01/lvol1

Hi,
That depends on what type of lvol you want to extend. If its an system LV then yes you have to go to single user mode, but if you have onlineJFS then you could extend them on the fly.

And the other LV can be increased without going to single user.
