How to use snapshots with BTRFS in Ubuntu

by user3005629   Last Updated May 08, 2016 08:00 AM

I installed Ubuntu in LVM partitioning but and I'm trying to follow this wiki and Whe I try to do pvcreate it gives me this :

sudo pvcreate /dev/sda1
  /run/lvm/lvmetad.socket: connect failed: No such file or directory
  WARNING: Failed to connect to lvmetad. Falling back to internal scanning.
  Device /dev/sda1 not found (or ignored by filtering).

sudo lvmdiskscan -v

I read "extended partition" in disks

The twilight OS

Does the Ubuntu installer actually makes a fully functional LVM partitioning during installation?
