Re: [linux-lvm] lvm oddities seen

Can anyone explain this for me?  I added a new hard drive to my LVM and
while lvdisplay of the LVM shows the full size of all disks/partitions in
the LVM, df -k does not:

[root bergamo sbin]# lvscan
lvscan -- ACTIVE            "/dev/lvm01/1" [176.76 GB]
lvscan -- 1 logical volumes with 176.76 GB total in 1 volume group
lvscan -- 1 active logical volumes

[root bergamo sbin]# lvdisplay /dev/lvm01/1
--- Logical volume ---
LV Name                /dev/lvm01/1
VG Name                lvm01
LV Write Access        read/write
LV Status              available
LV #                   1
# open                 1
LV Size                176.76 GB
Current LE             45251
Allocated LE           45251
Allocation             next free
Read ahead sectors     120
Block device           58:0

[root bergamo sbin]# df -k
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hda6             10317796   3808332   5985348  39% /
/dev/hda1                62193     17850     41132  31% /boot
none                     95628         0     95628   0% /dev/shm
/dev/lvm01/1         115382824  63615676  47078212  58% /mnt/lvm01.01

So while lvm shows the lvm size to be 176.76G, df -k shows the filesystem to be about 115G. What is happening with this?

Probably you have to extend your filesystem. Make resize2fs /dev/lvm/yourvolumename.
