RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

When cpuset is defined in the format "cpuset.cpus = CPU1,CPU2", cgconfig service fail to start. As per the documentation " http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Resource_Management_Guide/sec-cpuset.html" this should work.

Version-Release number of selected component (if applicable): libcgroup-0.36.1-6.el6.x86_64


How reproducible:

Add the following entries to /etc/cgconfig.conf and restart cgconfig service.
----------
mount {
cpuset = /cgroup/cgmnt;
}

group critical {
cpuset {
cpuset.cpus = 0,2;                  -->any cpu's separated by comma
cpuset.mems = 0;
}
}
----------

 
Actual results:

error at line number 7 at ,:syntax error
Loading configuration file /etc/cgconfig.conf failed
Failed to parse config file 

Expected results:

The service should start without any issues.

Subin

This is fixed by rebase to libcgroup-0.37 in RHEL 6.1, where double-quotes are allowed with anything inside, incl. comma.

cpuset {
cpuset.cpus = "0,2";
cpuset.mems = 0;
}

I let the bug open so our qa guys can check it.

using a cgconfig.conf containing:

mount {
cpuset = /cgroup/cgmnt;
}

group critical {
cpuset {
cpuset.cpus = "0,2";
cpuset.mems = 0;
}
}


[root@amd-dinar-01 etc]# /etc/init.d/cgconfig restart
Stopping cgconfig service: [  OK  ]
Starting cgconfig service: [  OK  ]
[root@amd-dinar-01 etc]# lscgroup
cpuset:/
cpuset:/critical
[root@amd-dinar-01 etc]# grep cgroup /proc/mounts 
cgroup /cgroup/cgmnt cgroup rw,relatime,cpuset 0 0
[root@amd-dinar-01 etc]# cat /cgroup/cgmnt/critical/cpuset.cpus 
0,2

[root@amd-dinar-01 etc]# uname -r
2.6.32-114.0.1.el6.i686
[root@amd-dinar-01 etc]# rpm -q libcgroup
libcgroup-0.37-1.el6.i686

It looks like this one can be verified.
