Hello, I've installed Slurm in a workstation (this is a single-node install) with Ubuntu 22.04, and have installed Slurm version 21.08.5 (I didn't compile it myself, just installed it with "apt install").
In the slurm.conf file I have: ,---- | ProctrackType=proctrack/cgroup | TaskPlugin=task/affinity,task/cgroup `---- When I submit a job, the "slurmd.log" shows: ,---- | [2023-04-21T12:22:14.128] task/affinity: task_p_slurmd_batch_request: task_p_slurmd_batch_request: 127018 | [2023-04-21T12:22:14.128] task/affinity: batch_bind: job 127018 CPU input mask for node: 0x00000001 | [2023-04-21T12:22:14.129] task/affinity: batch_bind: job 127018 CPU final HW mask for node: 0x00000001 | [2023-04-21T12:22:14.156] [127018.extern] error: cgroup namespace 'cpuset' not mounted. aborting | [2023-04-21T12:22:14.156] [127018.extern] error: unable to create cpuset cgroup namespace | [2023-04-21T12:22:14.156] [127018.extern] error: cgroup namespace 'memory' not mounted. aborting | [2023-04-21T12:22:14.156] [127018.extern] error: unable to create memory cgroup namespace | [2023-04-21T12:22:14.156] [127018.extern] error: failure enabling memory enforcement: Unspecified error | [2023-04-21T12:22:14.156] [127018.extern] error: Couldn't load specified plugin name for task/cgroup: Plugin init() callback failed | [2023-04-21T12:22:14.156] [127018.extern] error: cannot create task context for task/cgroup | [2023-04-21T12:22:14.156] [127018.extern] error: job_manager: exiting abnormally: Plugin initialization failed `---- If I change TaskPlugin to be just ,---- | TaskPlugin=task/affinity `---- then the job executes without any problems. Do you know how I could fix this while keeping the cgroup plugin? My intuition tells me that I should probably get the latest version of Slurm and compile it myself, but I thought I would ask here before going that route. Any ideas/pointers?
