Hi, While testing pam_slurm_adopt with multiple jobs running on the node with Centos7, I realized that it was failing with error messages like: Jun 12 11:57:37 server pam_slurm_adopt[86395]: From 192.168.1.48 port 36512 as test1234: unable to determine source job Jun 12 11:57:37 server pam_slurm_adopt[86395]: Couldn't stat path '/cgroup/memory/slurm/uid_1002/job_104' Jun 12 11:57:37 server pam_slurm_adopt[86395]: Couldn't stat path '/cgroup/memory/slurm/uid_1002/job_105' Jun 12 11:57:37 server pam_slurm_adopt[86395]: Couldn't stat path '/cgroup/memory/slurm/uid_1002/job_106' Jun 12 11:57:37 server pam_slurm_adopt[86395]: Couldn't stat path '/cgroup/memory/slurm/uid_1002/job_107'
As explained in the documentation of the plugin, I knew that I had to change the subsystem in the function _inderterminate_multiple() and change "memory" by "cpuset' for my case. But I am not a fan of hard-coded things, so I decided to modify the plugin to accept a new option that I called "cgoup_subsystem". To select the subsystem used by slurm/cgroup, just set the value of subsystem after pam_slurm_adopt.so in /etc/pam.d/sshd, for example: account sufficient pam_slurm_adopt.so subsystem=cpuset If nothing is set, the default subsystem is memory like before. After that and with the proposed modifications, everything was working as expected: Jun 12 11:59:14 server pam_slurm_adopt[86610]: From 192.168.1.48 port 36644 as test1234: unable to determine source job Jun 12 11:59:14 server pam_slurm_adopt[86610]: action_unknown: Picked job 116 Jun 12 11:59:14 server pam_slurm_adopt[86610]: Process 86610 adopted into job 116 I am attaching the modified version. I believe that it will be useful for some people and might be added to the next version of pam_slurm_adopt.
