Content: LVM online replace a hard drive; dynamic add/remove physical volumes
Author: Catalin(ux) M BOIE
URL: http://kernel.embedromix.ro/docs/
Version: 0.1

. Prepare "physical" volumes
dd if=/dev/zero of=disk1.img bs=1M count=200
losetup /dev/loop1 disk1.img

pvcreate /dev/loop1
pvdisplay /dev/loop1

vgcreate vg1 /dev/loop1
pvdisplay /dev/loop1
vgdisplay vg1

lvcreate --size 50MB --name test1 vg1
lvdisplay vg1

. Replace a hard drive, on-line
dd if=/dev/zero of=disk2.img bs=1M count=200
losetup /dev/loop2 disk2.img
pvcreate /dev/loop2
# extend vg1 with the new drive
vgextend vg1 /dev/loop2
vgdisplay vg1
# migrate data from disk1 to disk2
pvmove [--verbose] /dev/loop1 /dev/loop2
# remove physical volume from volume group
vgreduce --verbose vg1 /dev/loop1
# Remove old disk
pvremove /dev/loop1
# Done!

. Take a snapshot
lvcreate --name snapshot1 --size 100M --snapshot vg1/test1
mount /dev/vg1/snapshot1 /mountpoint
lvdisplay vg1

. Remove a snapshot
lvremove vg1/snapshot1

. Resize a lv
lvresize /dev/vg1/test2 -L newsize

. Remove a logical volume
lvremove vg1/test1

. Remove a volumegroup
vgremove vg1
