Cluster not starting when mysqld_multi is used

r00fr00f EntrantInactive User Role Beginner
I have a Percona cluster.
For a new application I needed to run a non-clustered instance of mysqld on one node.
So I created a separate configuration in my.cnf, and everything worked great.

However, I decided to check if it runs after reboot, and found out that it does not.
Mysqld starts, but it doesn't try to access the cluster, despite all the setting regarding the clustered instance remained the same.

Here is the startup log:

If I return back to the single-instance my.cnf then this node joins cluster again.
Does myslqd_multi support clustered instances at all? And if it does, which option should I add?
