Hello, I tried this sequence of actions according to Documentation/cgroups/cgroups.txt: mount -t tmpfs cgroup_root /sys/fs/cgroup mkdir /sys/fs/cgroup/cpuset mount -t cgroup cpuset -ocpuset /sys/fs/cgroup/cpuset cd /sys/fs/cgroup/cpuset mkdir Charlie cd Charlie /bin/echo 2-3 > cpuset.cpus [root@h Charlie]# /bin/echo 1 > cpuset.mems /bin/echo: write error: Invalid argument [root@h Charlie]# /bin/echo $$ > tasks /bin/echo: write error: No space left on device Any ideas why are these two error ? BTW: [root@h Charlie]# df -h df: ‘/sys/fs/cgroup/systemd’: No such file or directory df: ‘/sys/fs/cgroup/cpu,cpuacct’: No such file or directory df: ‘/sys/fs/cgroup/memory’: No such file or directory df: ‘/sys/fs/cgroup/devices’: No such file or directory df: ‘/sys/fs/cgroup/freezer’: No such file or directory df: ‘/sys/fs/cgroup/net_cls’: No such file or directory df: ‘/sys/fs/cgroup/blkio’: No such file or directory df: ‘/sys/fs/cgroup/perf_event’: No such file or directory Filesystem Size Used Avail Use% Mounted on devtmpfs 991M 0 991M 0% /dev tmpfs 1002M 324K 1002M 1% /dev/shm tmpfs 1002M 2.9M 999M 1% /run tmpfs 1002M 0 1002M 0% /sys/fs/cgroup So it seems that there is 1002M available on /sys/fs/cgroup any ideas?
