Hi,

This is work well on my laptop that running Fedora 9 with no LVM but on CentOS 5.2 with LVM it cann't calculate the LVM volume, below is output of my system :

[root@centos-svr ~]# df -kPl Filesystem 1024-blocks Used Available Capacity Mounted on /dev/mapper/VolGroup00-LogVol00 274405432 18584656 241656808 8% / /dev/sda2 101105 19096 76788 20% /boot tmpfs 1682508 0 1682508 0% /dev/shm

and with the command of Stephen : [root@centos-svr ~]# df -Pkl | awk '/^/dev// { avail += $3/1024 } END { printf("%d Mb used\n",avail)} ' 18173 Mb used

Well, I get 18167, but that's not too far off.
