Ubuntu Server 20.04.3 webmin shows 196GB hard drive space but it's 1TB

de flag

I have loaded webmin on my Ubuntu Server 20.04.3. The dashboard of the webmin says 16.67 GB used of 196GB. But my disk size is not 196GB. I have a raid array of 1TB. If I click on hardware and look at the partition on local disks it shows two small partitions followed by a big partition of 952GB. So question is, why am I only being allowed to use 196GB from it?

NAME                        SIZE FSTYPE      LABEL MOUNTPOINT
sda                       931.5G
├─sda1                        1M
├─sda2                        1G ext4              /boot
└─sda3                    930.5G LVM2_member

I guess that you have an LVM volume with 196GB in your array. Please help us by running the following command line, `lsblk -o name,size,fstype,label,mountpoint | grep -v 'snap'` and edit your original question to show the result. Please render the output as `code` in order to make it easy to read.

I've placed the result as code in my original question

You can do different things with the LVM system: Either use the yet not used space for backup or a snapshot or simply increase the size of the root partition. There are 'lv' tools for that purpose. You can find tutorials via the internet, for example, search for **ubuntu lvm guide**.

This is a good guide https://www.tecmint.com/extend-and-reduce-lvms-in-linux/

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
