The solution is to use the -h option with the df command which will display information in a human-readable form: df -h
The /dev/sda5 is the system’s actual disk and the command df showed information in 1k-blocks which is difficult to interpret. When we executed the df command we were shown all the available space as well as the total used space (in numbers and percentage). The full form of df is Disk Filesystem and this is by default installed in Ubuntu 20.04 whose function is to show various file systems information and can be executed like shown below: df To check disk space via Ubuntu terminal, we will use the following two commands: 1) df command

To our good luck, they were not using encrypted partitions. The client set up the server using Ubuntu server edition 20.04LTS, and the disk partitions were using LVM (Logical Volume Manager). We’ve asked the client if it was OK for us to reset the password instead of recovering it (meaning that we would not even try to crack the mystery of what the previous password was and just set a new one), and thankfully, the client accepted our request. The machine owner only knew the username but had no idea about the complexity of the password. 22 November 2021 in GNU/Linux tagged bash / chroot / GNU/Linux / howtos / Logical Volume Manager / lvm / lvscan / mount / passwd / password / pvscan / ubuntu / Ubuntu server 20.04LTS / ubuntu-vg / vgchange / vgscan by TuxĪ few days ago, a client tasked us to recover the password of an Ubuntu server 20.04LTS.
