It does not store any personal data.Because volume groups and logical volumes aren’t physically tied to a hard drive, it makes it easy to dynamically resize and create new disks and partitions. In addition, LVM can give you features that your file system is not capable of doing.

Use the following command to scan Logical Volumes # lvmdiskscan -l LV Creation host, time ubuntu-VirtualBox, 15:53:04 +0530 LV UUID HIHbwx-q02y-euJn-ILzZ-kJdf-QrfU-vJDTKa VG UUID u7a2ko-lBKT-tREq-HVg0-DPeN-rltd-ZB5O3s PV UUID eGMc5G-B3Zl-TWyw-4Z8V-5yNt-5jTT-JXtAKX PV UUID MTcB8p-ipiE-H3Rq-0xvE-DbAY-GRdl-0L207A The size will be the exact file system size that you will be able to use in real-time. Now time to create Logical volumes, define specific sizes. We require to assign a name to the volume group. Physical volume "/dev/sdc" successfully created.Ĭreate a new volume group with created physical volumes. Physical volume "/dev/sdb" successfully created. We require at least two empty drives to create LVM partitions. Run the fdisk command to see what we have.

# apt install lvm2ĭisplay what drives can be managed with LVM # lvmdiskscan I have added one additional hard drive to create and explain the LVM scenario.Ĭheck what we have in storage, have a look. Here, for testing purposing, I will be using VirtualBox installed Ubuntu 21.04 machine. Logically Logical Volumes are equal to the partition on a physical device. This is the layer with which users will be interacting. Now, a group of Physical volumes altogether can be sliced into any number of Logical Volumes. Volume group extracts all defined features beneath Physical Volumes. This combines groups to act as a single drive. LVM combines physical volumes into a pool of storage which is called a Volume group. The very first building of LVM creation, basically physical block drives are called Physical volume here. For the production environment, it is recommended to keep Logical Volumes provisioning all the time. These slices can be added to the desired file system when required. Such volumes can be considered as slices of the hard drive. What all Local Volumes do is that it create chunks of hard drives which are known to be logical volumes. For critical file systems like / or /etc, it will be complicated to expend if no Logical Volumes provisions are taken care of initially. While working in the live production environment it’s very obvious to get out do space sometimes.

Welcome back! Here today we are going to learn how to configure LVM or Logical Volume Manager with Ubuntu 21.04.
