[linux-lvm] lv_usr not updated after extention

[Runar Ingebrigtsen]

Hi,

My system is running with LVM and the VG's vg_system and vg_data.

Extending any partition in vg_data just works.
Extending lv_swap in vg_system works.
But the extended space never shows up in the /usr partition lv_usr! Look 
yourself:

#df -h | grep usr
/dev/vg_system/lv_usr   1.4G  1.3G   82M  95% /usr

# lvdisplay /dev/vg_system/lv_usr
--- Logical volume ---
LV Name         /dev/vg_system/lv_usr
VG Name         vg_system
LV Write Access read/write
LV Status               available
LV #                    3
# open                  1
LV Size                 4.09 GB
Current LE              131
Allocated LE            131
Allocation              next free
Read ahead sectors      1024
Block device            58:3

How come? Is this caused by the /usr partition containing running system 
files?
If so, why does the change still not show up after a reboot?

Now, I would appreciate any help :) Thanks.

Extending the Logical Volume doesn't automatically extend your filesystem.
Use the filesystem specific resizer, which might require unmounting the filesystem
(e.g. resize2fs for ext2/3 or resize_reiserfs for reiser).
