I installed Ubuntu 14.04 recently. During the installation I did not create a separate partition for my home folder. I also accidentally encrypted my home folder. When i did 

sudo df

I got the result as

Filesystem                   Size  Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-root  455G  181G  251G  42% /
....

Why does this have a funny name instead of a normal '/dev/sdx'?

Please explain to me what this is?

The /dev/mapper/ubuntu--vg-root in place of a traditional /dev/sdxN block device just indicates that you chose to install the system using LVM2 logical volume management. See What is LVM and what is it used for?

  • I tried to install ubuntu with LVM option on windows hard drive with three partitions but canceled (didn't even begin) now I cannot see my partitions and using fdisk -l this ubuntu--vg-root` is shown, can I access my partitions and are my files still intact? – mohas May 18 '18 at 19:22
