Previously we have seen how to create a flexible disk storage using LVM. Here, we are going to see how to extend volume group, extend and reduce a logical volume. Here we can reduce or extend the partitions in Logical volume management (LVM) also called as flexible volume file-system. Ex...
For the demo purpose, I have used Ubuntu 22.04 system and attached 15GB disk to it. We will create LVM partition on this disk from the command line. Table of Contents Prerequisites Step 1) Identify New Attached Raw Disk Step 2) Create PV (Physical Volume) Step 3) Create VG (Volume Gro...
Create Physical Volume 4.Create Volume Group (VG). # vgcreate testvg /dev/xvdc1 /dev/xvdd1 Here, “testvg” is the VG name. Create Volume Group 5.Now use “vgdisplay” to list all details about the VG’s in the system. # vgdisplay ...
The vgreduce command shrinks the volume group by removing one or more PVs. But in case if the PV is in use by any of the LV, we have to first move the LVs onto some other free PVs using pvmove and then we can use the vgreduce command as
In this example, the disk size is set to 64 KiB, the policy is 100% sequential write. View the test results. Linux If you use an old version Linux OS, for example CentOS 6.5, and run fdisk to create partitions, the default start sector number will not be 4-KiB aligned, which ...
This article describes how to troubleshoot the chroot environment in the rescue virtual machine (VM) in Linux.
1) Prepare Physical Volumes Let’s suppose a new disk is attached to our linux system. Check the new disk using ‘ fdisk -l ‘ command and create the physical volume # pvcreate /dev/sdX Replace /dev/sdX with the appropriate device name for each physical volume. In my case new disk is...
