Dear Ahmet M.,

I've tried your recomendation but unfortunately it didn't work.

But I realized that when I restart the slurmctld.service the job starts, but I don't know why.

Before, the job was stucked in CF, but when I restart the slurmctl it changes to R.

Have any ideas?

Slurm log says that your prolog did not finish at 300 seconds.

Only possible cause that I see, is the line started with "sudo
/usr/bin/beeond start -F -P -b /usr/bin/pdsh".

You can put a timeout command at the begining of the sudo line to test:

timeout 150  sudo /usr/bin/beeond start -F -P -b /usr/bin/pdsh ......

If the problem is solved with the timeout command, you should check
sudoers permission is correctly set for password-less sudo command. You
can check permission by executing this sudo line as the slurm user.

If sudoers permission is correct, but command takes too much time, you
can increase this 300 seconds threshold.
