Adding a disk
- Set the partition type in fdisk to be
8e (Linux LVM)
- Add to LVM with
pvcreate path-to-device
Example: Add /dev/sda1 to LVM
|
# pvcreate /dev/sda1
|
Creating a volume group
Example: Create a volume group called testvg, with /dev/sda1 as the first disk
|
# vgcreate testvg /dev/sda1
|
Creating a logical volume
- Use
lvcreate -l extents -n logical-volume-name volume-group
- The amount of extents available per volume group can be found by looking at the output of
vgdisplay (listed as Total PE)
| Example: Create a logical volume called testvol in the volume group testvg, 2000 extents in size
|
# lvcreate -l 2000 -n testvol testvg
|
