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

FYI,

# 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  
:0  
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:  
0  
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).
