[slurm-users] Problem with permisions. CentOS 7.8

Hello, I have installed Slurm under CentOS 7.8 Kernel 3.10.0-1127.el7.x86_64. The Slurm version I have installed is 14.03.3 along with Munge 0.5.11. I know these are not the latest versions, but I wanted to have consistency in all my nodes. I am facing a problem when I try to start Munge in

Hi Rodrigo, I am already following the instructions, but when I start munge it does not work. I get this error (on journalctl): munged: Error: Failed to check logfile "/var/log/munge/munged.log": Permission denied But, I insist, the ownership is correctly set If I run munge -n I get: /va

Have you checked if SELinux is perhaps blocking this? Give a 'getenforce' command. If it reports back 'Enforcing' , then issue 'setenforce 0' and retry Regards, -- Jan-Albert van Ree Jan-Albert van Ree | HPC Specialist | Digital Services MARIN | T +31 317 49 35 48 | j.a.v@marin.nl

Re: [slurm-users] Problem with permisions. CentOS 7.8

Good check, but I don't believe it is necessary to disable SELinux in order to run Munge correctly. Our slurmctld server (CentOS 7.8) reports Enforcing. /Ole On 28-05-2020 20:37, Ree, Jan-Albert van wrote: Have you checked if SELinux is perhaps blocking this? Give a 'getenforce' command. I

What is in /var/log/munge/munged.log? Munge is quite strict about permissions in its whole hierarchy of control and configuration files, appropriately. On Thu, May 28, 2020 at 11:01 AM Rodrigo Santibáñez wrote: > > Hello, > > You could find the solution here > https://wiki.fysik.dtu.dk/niflheim/S

Re: [slurm-users] Problem with permisions. CentOS 7.8

Hi Ferran, Normally the munge and slurm services are run by two distinct users, but you said that you run munge as the slurm user? Questions: 1. Did you install the munge RPM from EPEL? 2. Did you check the instructions in https://wiki.fysik.dtu.dk/niflheim/Slurm_installation#munge-configur

Re: [slurm-users] Problem with permisions. CentOS 7.8

I have not checked on the CentOS7.8 a) if /var/run/munge folder does not exist then please double check whether munge has been installed or not b) user root or sudo user to do ps -ef | grep munge kill -9 //where PID is the Process ID for munge (if the process is running at all); else which munged

Re: [slurm-users] Problem with permisions. CentOS 7.8

also check: a) whether NTP has been setup and communicating with master node b) iptables may be flushed (iptables -L) c) SeLinux to disabled, to check : getenforce vim /etc/sysconfig/selinux (change SELINUX=enforcing to SELINUX=disabled and save the file and reboot) Thanks & Regards, Sudeep Naraya
