Hi,
-1023 is DER_PMIX, that commonly due to your ompi/pmix building/usage is incorrect.
You may check "which orterun" to see if the orterun path is the one built by DAOS package.
and for server loading cmd line, at least you need "--report-uri /root/daos/uuu" to allow the dmg client can hook with it (by --ompi-server option).
