Description
I have been working on Async Rebuild Server for 2 days now, and I cannot get it to work. I have excellent notes from previous installs, but now on 25.10.1 on cloud machines something has changed and I cannot tell what it is.
I have completely disabled the firewall on every host. The only thing that maxscale tells me is:
2026-02-03 20:30:35 error : [mariadbmon] Could not parse pid from text 'Agent pid 119188'.
|
2026-02-03 20:30:35 error : [mariadbmon] Could not parse pid from text 'Agent pid 119188 killed'.
|
From that error, I cannot understand what is causing the failure.
From the ssh logs on the master (/var/log/auth.log), I see this:

It appears the command root is running is:
/usr/bin/lsof -n -P -i TCP:4444 -s TCP:LISTEN
|
When I run that as root, I get no output, and no error.
What failed? Why can't the error message in maxscale explain the problem better?
