Dear Slurm user community,
I am new to slurm and trying to start a slurmd and slurmctld on same machine. I
started with slurmctld which is having issues.
slurmctld: ext_sensors/none: init: ExtSensors NONE plugin loaded
slurmctld: debug: MPI: Loading all types
slurmctld: error: mpi/pmix_v3: init: (null) [0]: mpi_pmix.c:195: pmi/pmix: can
not load PMIx library
slurmctld: error: Couldn't load specified plugin name for mpi/pmix_v3: Plugin
init() callback failed
slurmctld: error: MPI: Cannot create context for mpi/pmix_v3
slurmctld: debug2: No mpi.conf file (/etc/slurm/mpi.conf)
We don't use PMIx here but this bit in the mpi.conf manpage
PMIxEnv=<environment variables>
Comma separated list of environment variables to be set in job
environments to be used by PMIx. Defaults to not being set.
suggests that you could set a LD_LIBRARY_PATH or similar EnvVar that
might expose your local PMIx library to Slurm jobs, so maybe the
daemons need similar.
Maybe try running the daemon startup with a lookup path set?
