+ <h2>What is LVM?</h2>
|
|
|
+
|
|
|
+<blockquote><em>LVM stands for Logical Volume Management. It is a system of managing logical volumes, or filesystems, that is much more advanced and flexible than the traditional method of partitioning a disk into one or more segments and formatting that partition with a filesystem. - <a href="https://wiki.ubuntu.com/Lvm" target="_blank">https://wiki.ubuntu.com/Lvm</a></em></blockquote>

|
|
+<h2>WARNING</h2>
|
|
|
+
|
|
|
+<blockquote>Below are the steps I took when I replaced my Proxmox 32GB microSD with a 64GB and cloned the installation from the old card to the new one. Do not attempt these steps without first having a backup as there is a high risk of data loss if the partition changes are unsuccessful</blockquote>
