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

[Jonathan Knudson <jknudson@xxxxxxxx>]

Have you seen this page?Â

https://research.cs.wisc.edu/htcondor/yum/

I'm also a little new to RHEL, well Linux in general. We run 7.2 here. Did you start the condor service as stated in the link?  ÂÂ

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:

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?
