I suppose the new maxBlockSize default is <>1MB, so your config parameter 
was properly translated. I'd see no need to change anything.

Hallo All,
we updated our Test-Cluster from 4.2.3.6 to V5.0.0.1. So good so fine, but 
I see after the mmchconfig release=LATEST a new common parameter 
?maxblocksize 1M? 
(our fs are on these blocksizes) is happening.
Ok, but if I will change this parameter the hole cluster was requestet 
that:
 
  root @sbdl7003(rhel7.4)> mmchconfig maxblocksize=DEFAULT
Verifying GPFS is stopped on all nodes ...
mmchconfig: GPFS is still active on SAPL7012x1.t7.lan.tuhuk.de
mmchconfig: GPFS is still active on SBDL7001x1.t7.lan.tuhuk.de
mmchconfig: GPFS is still active on SAPL7013x1.t7.lan.tuhuk.de
mmchconfig: GPFS is still active on SAPL7009x1.t7.lan.tuhuk.de
mmchconfig: GPFS is still active on SAPL7008x1.t7.lan.tuhuk.de
mmchconfig: GPFS is still active on SBDL7003x1.t7.lan.tuhuk.de
mmchconfig: GPFS is still active on SBDL7004x1.t7.lan.tuhuk.de
mmchconfig: GPFS is still active on SAPL7001x1.t7.lan.tuhuk.de
mmchconfig: Command failed. Examine previous error messages to determine 
cause.
Can someone explain the behavior here, and same clarification in an update 
plan what can we do to go to the defaults without clusterdown.
Is this a bug or a feature;-)
