Hi Marcus
thanks for your contact. I'm new to slurm deployment and I do not
remember where I found this command to check slurm setup. The
SallocDefaultCommand is not defined in my slurm.conf file
That is strange for me is that it works on the node hosting slurmctld,
and on the compute node too.
On the compute node, connected as root and then using "su - begou":
[root@tenibre-0-0 ~]# *su - begou*
Last login: Tue Nov 10 20:49:45 CET 2020 on pts/0
[begou@tenibre-0-0 ~]$ *sinfo*

salloc: Relinquishing job allocation 45
[begou@tenibre-0-0 ~]$
On the management node, connected as root and then using "su - begou"
(with no home directory available):
[root@management1 ~]# *su - begou*
Creating home directory for begou.

But not on the login node where I need it....

Yes I try this but wasn't able to find pertinent information. *This is
what I get*:
[begou@tenibre ~]$ *salloc -n 1 "srun -vvvvv hostname"*
salloc: Granted job allocation 43
salloc: error: _fork_command: Unable to find command "srun -vvvvv
hostname"
salloc: Relinquishing job allocation 43
[begou@tenibre ~]$ salloc -n 1 srun -vvvvv hostname
salloc: Granted job allocation 44
