Problem

Checking if super_read_only is defined and turned on..DBD::mysql::st execute failed: Unknown system variable 'super_read_only' at /usr/local/share/perl5/MHA/SlaveUtil.pm line 245.

simple workaround

 my $sth = $dbh->prepare("SELECT \@\@global.super_read_only as Value");
 =>  my $sth = $dbh->prepare("SELECT 0 as Value");
