Purpose
This short guide is meant for those of us who, more often that not find themselves struggling to remember the order to resizing LVM partitions, myself included. 😀
Configuration in four steps
Given you already have a working configuration of LVM up and running on Linux, with the appropriate physical volumes (PV) and logical volumes (LV) inside a volume group (VG). There is an order to how we go about resizing them, which can be summed up in four steps.
Note to self: Backup current state before proceeding and verify the results of each step.
-
Resize the disk partition on your machine to include/discard the unpartitioned/partitioned space you want.
-
Resize your LVM physical volume with
pvresize <disk partition path>. -
Resize your LVM logical volume with
lvresize <logical volume path> -l <size>. -
Grow your LVM logical volume on the file system level with
resize2fs.
If hell hasn’t broken loose in some shape or form, you should have successfully resized your LVM partitions.
