lvextend

[Bona_1]

Hello all,
yet another question. I used the command "lvextend" to expand an lvol, and the system acknowledged that the lvol had been expanded. however, when i run "bdf", it still shows the old size of the lvol, and installing applications in the lvol keep complaining about insufficient space. running a "vgdisplay -v" on the volume group however, it shows the expanded size. Can anyone tell me how to get the increase to show up with a "bdf"?

Thanks
Bona

Hello Bona,

You need to extend the file system:

EXAMPLE:
extendfs -F vxfs /dev/vgXX/rlvolX

Hope this helps!

Bona,

From the man page for extendfs:

EXAMPLES
To increase the capacity of a file system created on a logical volume,
enter:

umount /dev/vg00/lvol1

lvextend -L larger_size /dev/vg00/lvol1

extendfs -F hfs /dev/vg00/rlvol1

mount /dev/vg00/lvol1 mount_directory

Bona,

SAM will do it all for you, extending both lvol and fs.

..or another way...

check and see if you have OnlineJFS. If you do than you can increase using:

fsadm -F vxfs -b m /mountpoint

yes that is a small letter m directly after the size (no space in between).

Rgrds,
Rita

Hi,

To extend the size of a lv, you have to use two commands,

lvextend / extendfs if you don't have onlineJFS.
lvextend / fsadm if you have onlineJFS.

If you don't have onlineJFS, do a lvextend, unmount the filesystem and do a extendfs to extend the size of the filesystem.

If you have OnlineJFS, do a lvextned and then do fsadm -b /mount_point to extend the size of the filesystem without unmounting the filesystem.

Hope this helps.

As others have said, lvextend and extendfs or fsadm.

Here's a good doc on Managing File Systems:

How did you extend it.See the following example.
With online JFS for example if you wish to increase /opt to new size of 3GB
#lvextend -L 3000 /dev/vg00/lvolxxx
#fsadm -F vxfs -b 3000M /opt
