If you want to add new disks to an existing LVM volume to expand its size, you can easily do it, and below is the procedure on how to do – Configuration This flexibility partitioning allows you to manage storage space more efficiently as disk usage change from time to time. There is no limit of the physical disk boundary in LVM logical volumes, so you can create a large LVM volume that spans across multiple smaller physical disks. The filesystem on /dev/vg00/lv01 is now 25588736 (4k) blocks long.This article helps us to add a new disk to LVM ( Logical Volume Manager), the very best advantage of LVM over normal disk partitions is its support for “dynamic partitions” you can create and resize (expand or shrink) LVM volumes dynamically as we needed. Old_desc_blocks = 10, new_desc_blocks = 13 To resize the file system to the new size using resize2fs, enter the resize2fs command in the following ~]# resize2fs [PATH OF LOGICAL resize2fs /dev/vg00/lv01įilesystem at /dev/vg00/lv01 is mounted on / on-line resizing required Resize the file system to use the new space.
Logical volume vg00/lv01 successfully resized. Size of logical volume vg00/lv01 changed from 77.61 GiB (19869 extents) to 97.61 GiB (24989 extents). To increase the size of the logical volume with the lvresize program, type the lvresize command in the following ~]# lvresize -l +100%FREE # lvresize -l+100%FREE /dev/vg00/lv01 In this example, the path is /dev/vg00/lv01. Note the path of the logical volume that you want to enlarge.

If you have the distribution Debian 10 or Debian 11 installed on your server, you need to install the growpart program. If you have the distribution Ubuntu 18.04, Ubuntu 20.04 or Ubuntu 22.04 installed on your server, the growpart program is already installed by default.
