LVM sort of like an extended partition, in that other partitions
reside within the logical volume. Here's what my drive looks like.
workstation:~ # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 2.1G 395M 1.7G 20% /
/dev/system/home 4.0G 809M 3.3G 20% /home
/dev/system/isos 2.0G 33M 2.0G 2% /isos
/dev/system/opt 2.0G 811M 1.3G 40% /opt
/dev/system/usr 6.3G 2.2G 4.1G 35% /usr
/dev/system/local 2.0G 103M 1.9G 6% /usr/local
/dev/system/var 2.0G 292M 1.8G 15% /var
tmpfs 188M 0 188M 0% /dev/shm
/dev/system is the logical volume.
I haven't experienced the problem that Carl mentioned. It may be the
fact that I'm using reiserfs instead of ext3, or that I've just been
lucky. I have had power failures and the system came back up fine
after power was restored. Need to get a new battery for the UPS for
this system.
