I suspect if slurm mounted the cgroup as cpu,cpuacct then it would work. but it's because it's trying just cpuacct that it's failing. that's the sort of behaviour I've seen before.
the OS appears to bind mount them if they're the same.
Bingo! You are a star sir. :-) [root@spartan001 ~]# mount -v -t cgroup -o cpuacct none /cgroup/cpuacct mount: none is already mounted or /cgroup/cpuacct busy [root@spartan001 ~]# mount -v -t cgroup -o cpu,cpuacct none /cgroup/cpuacct mount: none mounted on /cgroup/cpuacct.
you have the slurm source - care to hack it and give that a go?
I suspect I'll just open a bug with SchedMD tomorrow and let them fix that, I've got my hands with my other work full until next year now.
torque 6's cgroup code uses cpu,cpuacct which I presume is in order to play nicely with rhel7.
Yeah, sounds like it.. Thanks Robin! :-) -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC
