[slurm-dev] Re: cgroup error

[Fulcomer, Samuel]

This is due to newer versions of SLURM using /sys/fs/cgroup (as in RHEL7)
rather than /cgroup (as in RHEL6). It would have been a no-brainer to check
and do the right thing, but as it is, you have to specify the cgroup mount
point in cgroup.conf if you're on the wrong system for your slurm version.

slurmd could be a little more explicit with its error messages...

It would have to work in Linux before slurm could use it. Here is the red hat 
guide.

Hi Slurm-Dev,

I again tried setting up SLURM but it is not able to setup the cgroups.

I tried setting up the cgroups manually, but I am getting the error that the 
filesystem of type cgroup is unknown. I looked around for some solution but 
have been unable to find it.  Does anyone have any recommended solution to fix 
this issue?

root@mini12:/home/utilite# slurmd -cDvvv
slurmd: topology NONE plugin loaded
slurmd: debug:  Reading cgroup.conf file /etc/slurm-llnl/cgroup.conf
slurmd: debug2: unable to open '/cgroup/freezer//release_agent' for reading : 
No such file or directory
slurmd: debug2: unable to get parameter 'release_agent' for '/cgroup/freezer/'
mount: unknown filesystem type 'cgroup'
slurmd: error: unable to mount freezer cgroup namespace
slurmd: error: Couldn't load specified plugin name for proctrack/cgroup: Plugin 
init() callback failed
slurmd: error: cannot resolve proctrack plugin operations for proctrack/cgroup
slurmd: error: slurmd initialisation failed


Thanks.
