Re: New DAOS Setup
Hi,
If you are just using the daos_server_local.yml config file and do not need an NVMe, just change the nr_hugepages: 0. This takes care of the error and starts the server.

If NVMe is not required then try setting "nr_hugepages: 0" in the global section of the server configuration file.
