Hello.
After your mail I tried something;
I just curious what will happen when I downgrade multipath-tools package and
the rest was latest.
lvm2 2.02.181-1
device-mapper 2.02.181-1
I just downgrade to: multipath-tools 0.7.6-1
Everything works great. I didnt saw any problem.
I was thinking the problem related to device-mapper but now its seems
something else.
This is compile process from Arch-linux AUR repository:
https://paste.ubuntu.com/p/zV58g56gVT/
If I'm not mistaken this is the log you want. If its not then tell me where
should I look for the log you want?

I did not tried to compile from GIT by myself. But my knowledge the aur
package also takes the code from your git repository
If you need anything else just ask me please.
Hi
Wild guess - latest multipath probably started to require latest kernel
which has some enhanced support for polling events - which is not yet
used by dmeventd nor supported by libdm API.
And likely multipath fully?? switched to use this event mechanism and
there is no backward compatibility support for older kernel ?
Or maybe the detection and switch to old mechanism isn't properly working yet ?
