I wonder if this behaviour is not observe in Eoan because it is the first Ubuntu release introducing the removal of lvmetad[0] (starting v2_03_00) in favour of 'event_activation'[1] (starting v2_03_03) in lvm2.
Seems like a lot happened between lvm2 found in disco and eoan in term of development in the activation area.

The activation generator program now looks at the new lvm.conf setting "event_activation" (default 1) to switch between event activation and direct activation. Previously, the old use_lvmetad setting was used to switch between event and direct activation. ---- commit fc482406ec4e0607a9d7335ac927c64b361cad1c Author: Zdenek Kabelac <[email protected]> Date: Thu Nov 29 23:08:05 2018 +0100 make: generate config update ---- conf/example.conf.in: - # Configuration option global/use_lvmetad. - # This setting is no longer used. - use_lvmetad = 0 + # Configuration option global/event_activation. + # Activate LVs based on system-generated device events. + # When a device appears on the system, a system-generated event runs + # the pvscan command to activate LVs if the new PV completes the VG. + # Use auto_activation_volume_list to select which LVs should be + # activated from these events (the default is all.) + # When event_activation is disabled, the system will generally run + # a direct activation command to activate LVs in complete VGs. + event_activation = 1 - # Configuration option global/lvmetad_update_wait_time. - # This setting is no longer used. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854981 Title: system doesn't properly boot as expected if /usr is on its own LV To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1854981/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
