[slurm-users] srun problem -- Can't find an address, check slurm.conf

[Scott Hazelhurst]

Dear all

I still haven’t found the cause to the problem I raised last week where srun -w xx  runs for some nodes but not for others — thanks for the ideas.

One intriguing result I’ve had trying to pursue this which I thought I’d share in case it sparks some ideas. If I give the full path for srun, then it works


# show path
scott at cream-ce ~]$ which srun
/opt/exp_soft/bin/srun


# Node n37 is good (as are most of our nodes)
[scott at cream-ce ~]$ srun  -w n37 --pty bash
[scott at n37 ~]$ 


# Node n38 is not (and a few othrs)
scott at cream-ce ~]$ srun  -w n38 --pty bash
srun: error: fwd_tree_thread: can't find address for host n38, check slurm.conf
srun: error: Task launch for 20094.0 failed on node n38: Can't find an address, check slurm.conf
srun: error: Application launch failed: Can't find an address, check slurm.conf
srun: Job step aborted: Waiting up to 32 seconds for job step to finish.
srun: error: Timed out waiting for job step to complete

But if I  give the full path name — it works!

scott at cream-ce ~]$ /opt/exp_soft/slurm/bin/srun  -w n38 --pty bash
[scott at n38 ~]$
