Hello,

I have an issue with a cluster from 3 nodes and Group replication, oracle linux 9.7 and MYSQL CE 8.4.8.

Every time I restart the mysqld service the read_only and super_read_only remain ON.

If I check the cluster all nodes are online and primary and no errors (it`s a multi master).

What`s the problem ?

I`ve tried to set the /etc/my.cnf with setting:
read_only = OFF
super_read_only = OFF

but no success.

Once I restart mysqld service read_only came back to ON.

Thank you.
