Pbsnodes: Server has no node list

Hi folks,

Actually, it is the first time that I face an issue regarding the openpbs installation on my Centos 7 machine.

pbsnodes -a

pbsnodes: Server has no node list


qstat -Bf

Server: calc4
server_state = Active
server_host = XXX
scheduling = True
total_jobs = 0
state_count = Transit:0 Queued:0 Held:0 Waiting:0 Running:0 Exiting:0 Begun
default_queue = workq
log_events = 511
mail_from = adm
query_other_jobs = True
resources_default.ncpus = 1
default_chunk.ncpus = 1
scheduler_iteration = 600
flatuid = True
FLicenses = 20000000
resv_enable = True
node_fail_requeue = 310
max_array_size = 10000
pbs_license_min = 0
pbs_license_max = 2147483647
pbs_license_linger_time = 31536000
license_count = Avail_Global:10000000 Avail_Local:10000000 Used:0 High_Use:
pbs_version = 19.0.0
eligible_time_enable = False
max_concurrent_provision = 5
max_job_sequence_id = 9999999

Could you please assist me to figure out where this problem comes from? I have to mention that I have already tried the followings and no solution yet:

1- qmgr -c “create node hostname”
2- qmgr -c "set server flatuid = True "

Thanks for your help in advance.

When you run the above commands ( i suppose you are running them as root user) , what is the outcome ? do these command run successfully or have a error message displayed after they are run ? Also, could you please check the PBS Server logs in a parallel terminal , tail -f $PBS_HOME/server_logs/YYYYMMDD , to see the logging corresponding to the above commands

Please note

The “hostname” should be the name displayed by the hostname command run the compute node.
This hostname should be mapped to a static IP address and should be fully resolvable (forward/reverse) from PBS Server and Compute node(itself).
