Hi Folks,
On the 250 node scale testing we notice that the storage configured in the controlplane CR for galera was not sufficient and we tried configuring it from 500M to 5G but statefulset did not allow it. 

Also if we increase the replica to higher number and increase the storagerequest say 5G only the newly scaled replica has the PV 5G but the already existing one still has 500M configured.
