extend FS

[Francis Flan]

I found a VG01 on a 11.31 server and pvdisplay says it is 70GB.
There's 1 lvol on the VG and it is 40GB in size.

OnlineJFS is NOT installed on the system.

Can i increase the filesystem from 40GB to 70GB without losing data currently on it?

thanks,
Fran

Yes.

lvextend -L 70000 /dev/vg01/lvolname (or use -l with # of extents )
unmount /lvolname
extendfs /dev/vg01/rlvolname
mount /lvolname

Hi Fran:

Without OnlineJFS installed you will have to unmount the filesystem and use 'extendfs' to increase its size.

Begin, of course, by enlarging the logical volume with 'lvextend'. Unmount the filesystem associated with that logical volume and 'extendfs' it. Then, re-mount the filesystem.

As long as you are not shrinking the logical volume or the filesystem no data will be lost.

Regards!

Well. It is already explained above. But to make it more clear:

lvextend -L 71680 /dev/vg01/lvol1

(I will use 71680 MB) and the size will be rounded up according to your PE size value.
lvdisplay /dev/vg01/lvol1

Then you have to unmount the filesystem:

umount /dirname
(make sure the LV is unmounted), then

extendfs -F vxfs /dev/vg01/lvol1

mount the LV to /dirname

Dear Francis

if online jfs is not installed u have to use the command extendfs if online jfs is there u can use fsadm
if online jfs is there no need to umount
if online jfs is not there u have to umount

in u case there is no online jfs

so first u have to umount the file system
umount /mnt where mnt is u mount point
here i am taking mnt is an example
i don't where it is mounted in u case

lvextend -L size of the logical volume /dev/vg01/lvolumename
mount -F vxfs /dev/vg01/lvolumename /mnt
where
F is the file system type

thanks and regards
