-So, like me, you installed Ubuntu and accepted the default use of lvm and now your operating volume is very small and the Ubuntu installer did not utilize the entire physical drive. There is a ton of free space that is not being utilized.  And,  possibly, your freshly installed cloud application (NextCloud) will soon exceed the allotted space within the first week or so as a result of data uploading or synchronization.+So, like me, you installed Ubuntu and accepted the installers default selections for lvm and now your operating volume is very small and the Ubuntu installer did not utilize the entire physical drive.
