Why can't I create a physical volume?
0
I was wondering why I can't create a physical volume? Every settings are default for lvm just installed (
For cat /etc/lvm/lvm.conf see https://paste.ubuntu.com/p/QqrszWR8M9/).
Is it because of "Failed to start lvm2.service: Unit lvm2.service is masked"? Thanks.

Can't open /dev/sda2 exclusively. Mounted filesystem?

You're trying to use the entire /dev/sda for a PV. But you've got (at least) two partitions on that disk (sda1 and sda2), so LVM is rightly refusing to honour your request.

It's got a filesystem on it. LVM is doing its best to stop you breaking your system.
