[Xen-users] lvm size

[Anand <xen.mails@xxxxxxxxx>]

This could be considered OT however i can't seem to find an answer to this one. I will appreciate if someone can help me out.

I created a new logical volume of 3G, then issued cat of a flat file of centos to it. The flat file is of 1GB.

cat /home/anand/images/centos.img > /dev/vgxen/test7

lvscan shows 3GB allocated
[root@xen tmp]# lvs
  LV         VG    Attr   LSize   Origin Snap%  Move Log Copy%
  test7      vgxen -wi-a-   3.00G
  test7-swap vgxen -wi-a- 256.00M

after mounting it shows a size of 1GB approx. i.e. the same size as the flat file.
df -h
/dev/mapper/vgxen-test7
                      986M  475M  462M  51% /tmp/xen-server-tools.Cl7947

After this when i mount the volume it shows up as 1gb in size and vgs shows 3gb allocated to it. While using flat files i remember i could use resize to get the new flat file size back. However in case of volumes how do i do so ?

P.S. Can anyone recommend a better way to create file systems inside volumes than the above method ?
