Hi

You do a
lvextend -L (size) lvol_name (/dev/vg00/lvolx

then

fsadm -b (size with a M for Mb) (mount_point)

Hope this helps

hello ,
i could not use fsadm ..what should be the procedure to extend the file system normaly with out online JFS.please help

[Coolmar]

I don't recall using fsadm, I only used lvextend -L size in mb /dev/vgXX/lvolX

That should do it for you. So say /dev/vg02/lvol1 is at 2000MB right now and you want to increase it to 3GB...type

# lvextend -L 3000 /dev/vg02/lvol1

Then do a bdf and see if that worked.

[Coolmar]

Sorry, I was wrong. You DO need fsadm. Why is yours not working? Do you get an error message? If so, what does it say?

lvextend
followed by
extendfs /dev/vgXX/rlvolXX
fsck

Here are the steps BTW for extending it when you don't have onlineJFS:

Unmount the file system.


#umount /dev/vg01/lvol1


Increase the size of the logical volume.


#/usr/sbin/lvextend -L 1200 /dev/vg01/lvol1


Note that the -L 1200 represents the new logical volume size in MB, not the increment in size.

Increase the file system capacity to the same size as the logical volume. Notice the use of the character device file name.


#extendfs /dev/vg01/rlvol1


Re-mount the file system.


#mount /dev/vg01/lvol1 /project


Run bdf to confirm that the file system capacity has been increased.

[Coolmar]

Did you activate it?

# vgchange -a y /dev/vgXX
