====== Examples of using LVM ======

===== Resizing volumes ====

Here we show how to increase vg-srv reducing vg-var inside one logical volume group.

<code bash | Activate logical volumes>
vgchange -a y ; lvs
</code>

<code bash | Shrink vg-var LVM without dataloss>
umount /dev/mapper/vg-var # umount
e2fsck -f /dev/mapper/vg-var # check
resize2fs /dev/mapper/vg-var 2670G # reduce size to 2670G
lvreduce -L 2676G /dev/mapper/vg-var # reduce logical volume size to 2676G
resize2fs /dev/mapper/vg-var # fit the LVM volume
</srv>

<code bash | >
lvresize --size +1600M /dev/mapper/vg-srv # increase volume size
e2fsck -f /dev/mapper/vg-srv # check
resize2fs /dev/mapper/vg-srv # grow up fs size
e2fsck -f /dev/mapper/vg-srv # check
</code>
