Comment 2 for bug 1771987

Hi,

I got this issue resolved.

I saw lvm2-lvmetad service was disabled but it was active.

root@ubuntu-Compute1:~#
root@ubuntu-Compute1:~# systemctl status lvm2-lvmetad
● lvm2-lvmetad.service - LVM2 metadata daemon
   Loaded: loaded (/lib/systemd/system/lvm2-lvmetad.service; disabled; vendor preset: enabled)
   Active: active (running) since Tue 2018-06-05 15:09:32 +08; 2h 10min ago

           └─1023 /sbin/lvmetad -f

Jun 05 15:09:32 ubuntu-Compute1 systemd[1]: Started LVM2 metadata daemon.
-----------------------

Executed these series of commands and lvm2 was enabled and things started working.

 systemctl enable lvm2-lvmetad.service
 systemctl enable lvm2-lvmetad.socket
 systemctl start lvm2-lvmetad.service
 systemctl start lvm2-lvmetad.socket

 systemctl status lvm2-lvmetad
