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
