Re: [HTCondor-users] HTCondor 8.4 on CentOS 7 - control groups

[Klint Gore <kgore4@xxxxxxxxxx>]

Mine's happy with it.  In my /usr/lib/systemd/system/condor.service, I have the line "ControlGroup=/condor".

My systemd is 219-19.el7_2.9.

FWIW selinux and firewalld are enabled.

Klint.

Trying to stand up an HTCondor Central Manager is probably not the best way to introduce onself to systemd and CentOS 7, but here I am.

The stock RPM for 8.4.8 for EL7 downloaded from UW results in the following errors thrown by systemd:

$ sudo systemctl status condor
● condor.service - Condor Distributed High-Throughput-Computing
   Loaded: loaded (/usr/lib/systemd/system/condor.service; enabled; vendor

$

I see a ControlGroupAttribute lvalue documented, at least.

I've set up the cgconfig.conf as documented in the manual, and once I found the /sys/fs/cgroup directory I was able to find the /sys/fs/cgroup/cpu/htcondor directory, so it does appear to be working after a fashion, but I'm not clear on whether I actually need to do the cgconfig.conf update at all?

I'm currently running systemd 219-19.el7_2.7, and the latest available from CentOS Updates is .13.

Any suggestsions out there from anyone running HTCondor on RHEL / CentOS 7?
