To resize or extend a Volume group you can either add a new Physical Volume or extend an existing Physical volume. In the latter case, VG automatically recognizes the new increase size whereas in the former case you have to extend the VG using vgextend. Let’s see an example of resizing the existing PV .

pvresize – Unix, Linux Command – Tutorialspoint, iii) By extending the size of the LUN from storage side and then using the pvresize command to increase the size of the PV and then the existing filesystem. In this tutorial we are going to teach you method number 3 and you will learn how to extend the filesystem using pvresize command in a physical Linux server.. Note: The disk should be not partitioned like sdc1, sdc2, etc.
Expand the PV on /dev/sda1 after enlarging the partition with fdisk: pvresize /dev/sda1. Shrink the PV on /dev/sda1 prior to shrinking the partition with fdisk (ensure that the PV size is appropriate for your intended new partition size): pvresize –setphysicalvolumesize 40G /dev/sda1. RESTRICTIONS, 7/30/2014 · So, now we can’t extend the lvm size, for extending we need to add one physical volume (PV), and then we have to extend the volume group by extending the vg. We will get enough space to extend the Logical volume size. So first we are going to add one physical volume. For adding a new PV we have to use fdisk to create the LVM partition.
VMware allows to extend the size of a virtual disk online – when the VM is running. The next expected steps for Linux system are: extend the partition: delete and create a larger one with fdisk; extend the PV size with pvresize; use free extents for lvresize operations; and then resize2fs for file system; But I am stuck on the first step: fdisk and sfdisk still display the old size for the disk.
Environment. Red Hat Enterprise Linux 7; Issue. Both Xen and KVM support online resize of the virtual block devices that the virtual machines use. Unfortunately, since the partitions in the boot virtual block device are already in use, those can’t be modified online and the virtual machine won’t pick up the changes on the boot virtual block device without a reboot.
