So if I have this disk partition:
[root@uszmpdblp010la mysql]# df -h /mysql Filesystem Size Used Avail Use% Mounted on /dev/mapper/MysqlVG-MysqlVol 9.9G 1.1G 8.4G 11% /mysql
thats not a partition thats a file system on a logical volume...
# df -h /mirror Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_sg1data-lvmirror 1.0T 736G 289G 72% /mirror
