I am using a SLES 12 VM where I have installed a service called as besclient using an RPM. When I uninstall the agent and remove the files the status of the service still shows ac active. I checked and found these 2 files still remain.

/sys/fs/cgroup/pids/system.slice/besclient.service
/sys/fs/cgroup/systemd/system.slice/besclient.service

which I am unable to remove using rm -rf command. How to remove these kind of files? 

rm: cannot remove '/sys/fs/cgroup/pids/system.slice/besclient.service/tasks': Operation not permitted

I am running this as root.

The /sys filesystem provides a filesystem-like view on information and config settings of the kernel. I.e., these are not "really" files, that is why you cannot delete them.

Persistent cgroups are released when the unit is disabled and its configuration file is deleted by running:

~]# systemctl disable name.service

where name stands for the name of the service to be disabled.

Apparently something is still running. Try: cat /sys/fs/cgroup/pids/system.slice/besclient.service/tasks to see if you can find a process PID.

  • This is after disabling the service. Also when I check status of the service service besclient status â besclient.service - Besclient Daemon Loaded: loaded (/usr/lib/systemd/system/besclient.service; disabled; vendor preset: disabled) Active: active (exited) since Tue 2018-05-15 12:27:13 UTC; 2h 17min ago Main PID: 10687 (code=exited, status=0/SUCCESS) Tasks: 0 (limit: 512) CGroup: /system.slice/besclient.service May 15 12:27:13 deehdss013ccp systemd[1]: Started Besclient Daemon.

  • Try `systemd-cgls` – Gerrit May 15 '18 at 14:46
  • No output `systemd-cgls | grep bes` – codec May 15 '18 at 14:48
  • Did you try a `systemctl daemon-reload`? – Gerrit May 15 '18 at 14:57
