CGROUPFS-MOUNT(8) |
NAME¶
cgroupfs-mount, cgroupfs-umount - set up cgroupfs mount hierarchies
SYNOPSIS¶
Control groups are a kernel mechanism for tracking and imposing limits on
resource usage on groups of tasks. These scripts mount and unmount the
hierarchies for managing them.
cgroupfs-mount
cgroupfs-umount
DESCRIPTION¶
The location for the mounts these scripts create is /sys/fs/cgroup, which
is widely regarded as "the place" for these to be mounted (for
example, systemd mounts them here as well).
RETURN VALUE¶
Zero for success or if it is determined that we can or should not mount, due to
user entries in /etc/fstab or pre-existing mounts. Non-zero for
explicit failures.
CAVEATS & DIAGNOSTICS¶
It is critically important for the proper operation of these scripts that you do
not manually include any cgroup mount points in /etc/fstab. After
commenting out any extraneous cgroup entries in /etc/fstab, you should
either reboot or manually umount them and then run
cgroupfs-mount again.
RESTRICTIONS¶
These scripts intentionally do not do any cgroup management or classification of
tasks into cgroups. They are also very intentionally light on configurability
(to the point of non-existence) to keep the implementation simple and less
error-prone.
