Update from 8.0.19-10.1 to 8.0.20-11.3 works, but after update status and variables are not shown
I have a very strange problem: After update from 8.0.19-10.1 to 8.0.20-11.3 the following queries show nothing:
mysql> SHOW STATUS; Empty set (0.11 sec) mysql> SHOW VARIABLES; Empty set (0.01 sec)
But, the cluster is in sync, all cluster node are joined. The same configuration works, when I do a new installation with the newest (8.0.20-11.3) version of cluster software. I'm running on CentOS 8.1. The procedure is reproduce able, I have Snapshots of the VM's.
