Regarding the blog post https://bit.ly/2Nlk6Hc there´s an important information ( thanks to Martin Vogel ):

if you have a database where DAOS is enabled and you create a replica on another server ( which also has DAOS enabled ) with the command

“cl copy Server1!!dev/demo.nsf Server2!!dev/demo.nsf replica“

we could see that DAOS is NOT enabled on the target server !! Therefore we opened a case ( CS0206615 ) at HCL. Hopefully this issue will be fixed in V12 😉
