This documentation provides a general tour to DAOS management commands (dmg) for daos_admin, and DAOS tools (daos) for daos_client users. Provides help with pool and container create, list, query and destroy on DAOS server for daos_admin and daos_client users. Some frequent common errors and workarounds for new users when using the dmg and daos tools.  Example runs of data transfer between DAOS file systems, by setting up of DAOS dfuse mount point and run traffic with dfuse fio and mpirun mdtest. Example of basic dmg and daos tools runs on 2 hosts DAOS server and 1 host client, runs of DAOS rebuild over dfuse fio and mpirun mdtest on a 4 hosts DAOS server.
