[linux-lvm] Disk size reporting.

[linux-lvm] Disk size reporting.

[Jim Ford]

I think I've extended a logical volume correctly, but DF shows no change.

lvs output:
  LV     VG     Attr   LSize   Origin Snap%  Move Copy%
  root   Ubuntu -wi-ao  25.13G
  swap_1 Ubuntu -wi-ao 656.00M

df output:
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/Ubuntu-root
                      18715076   2909852  14854544  17% /
tmpfs                   112264         0    112264   0% /dev/shm
tmpfs                   112264     12588     99676  12% 
/lib/modules/2.6.12-10-386/volatile
/dev/hda1               233335     19166    201721   9% /boot

Have I extended my Ubuntu volume correctly, please?

<sigh> Life was _so_ much simpler without lvm and udev! </sigh>

You just extended your volume, not your filesystem, don't you ;-). I 
don't know, which filesystem Ubunto uses for root and if it's ext2/ext3, 
if they use the online-resize patches.

So, seak for into how to resize/extend the filesystem you use.

Cheers
Klaus

The LVM FAQ entry for "Extending a Logical Volume" even covers this issue, and
tells you how to do it for several filesystems:
