Dear all, I have met a straight problem in my recent operation. Previously, I can do the following operations: # mount -t cgroup cgroup /mnt/cgrp # cd /mnt/cgrp # mkdir test # echo $$ > test/tasks # rm -rf test but now I met the straight permission with the same operation while I am root: # mount -t cgroup cgroup /mnt/cgrp # cd /mnt/cgrp # mkdir test # echo $$ > test/tasks -bash: echo: write error: No space left on device # rm -rf test rm: cannot remove `/mnt/cgrp/test/cpuset.memory_spread_slab': Operation not permitted rm: cannot remove `/mnt/cgrp/test/cpuset.memory_spread_page': Operation not permitted rm: cannot remove `/mnt/cgrp/test/cpuset.memory_pressure': Operation not permitted ... I guess maybe the permission attributes block my operation, but I checked with lsattr and got the following message: # lsattr /mnt/cgrp/test lsattr: Inappropriate ioctl for device While reading flags on /mnt/cgrp/test/cpuset.memory_spread_slab lsattr: Inappropriate ioctl for device While reading flags on /mnt/cgrp/test/cpuset.memory_spread_page lsattr: Inappropriate ioctl for device While reading flags on /mnt/cgrp/test/cpuset.memory_pressure ... I have no idea how to fix it. Any help? Thank you very much, Anqin _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
