[one-users] " Datastore 0 filtered out. It does not fulfill SCHED_DS_REQUIREMENTS." error after upgrade from 4.2 to 4.4

[Gerry O'Brien]

Hi Ruben,

     Thanks for your reply. I read that paragraph but did not fully

multi-system DS it did not apply to our configuration,

         Regards,
             Gerry
