Lvm linux - how to create logical volumes

Steps to have lvm running on your system.

- find a partition or disk that is not used - I have /dev/sda10
- pvcreate /dev/sda10 (creates the physical volume)
- vgcreate VolGroup00 /dev/sda10 (creates a volume group)
- lvcreate -L 40GB -nTempVolume VolGroup00 (create a volume with 40GB with the name TempVolume under the volume group VolGroup00)
- mkfs.ext3 /dev/mapper/VolGroup00-TempVolume (creates the filesystem ext3 type on the TempVolume)
- mkdir /mnt/IMAGE (create a directory to mount the volume)
- mount /dev/mapper/VolGroup00-TempVolume /mnt/IMAGE
- mount (shows /dev/mapper/VolGroup00-TempVolume on /mnt/IMAGE type ext3 (rw))

That's it! You can start using the new mount point.
