Hi,

I can replicate this locally now;-)

...

I can confirm that the message "WARNING: There are still devices being monitored." comes from dmeventd (the string is in the /usr/sbin/dmeventd executable). I can confirm that the dmeventd process is running after boot. And yet:

According to "man dmeventd", it will be started to run when mirror/raid/snapshot/thin feature(s) is/are used. In your case, it's "thin pool" - system-pool0-tpool being monitored. The time when we create/activate a thin pool is good chance to start this deamon, which can be done within the code of LVM tools' commands.

Enabling the "dm-event.service" explicitly works for me. Could you have a try?

# systemctl enable dm-event.service Created symlink from /etc/systemd/system/sysinit.target.wants/dm-event.service to /usr/lib/systemd/system/dm-event.service. It's enabled now. I'll let you know after my next reboot how it goes (shouldn't take long, this machine crashes on suspend and on hibernate very often). -- You are receiving this mail because: You are on the CC list for the bug.
