|
|
.SH NAME |
|
|
|
cgroupfs-mount, cgroupfs-umount \- set up cgroupfs mount hierarchies |
|
|
|
.SH 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. |

|
|
|
.SH DESCRIPTION |
|
|
|
The location for the mounts these scripts create is |
|
|
|
.IR /sys/fs/cgroup , |
|
|
|
which is widely regarded as "the place" for these to be mounted (for example, |
|
|
|
.BR systemd |
|
|
|
mounts them here as well). |
|
|
|
.SH "RETURN VALUE" |
|
|
|
Zero for success or if it is determined that we can or should not mount, due to user entries in |
|
|
|
.IR /etc/fstab |
|
|
|
or pre-existing mounts. |
|
|
|
Non-zero for explicit failures. |
|
|
|
.SH "CAVEATS & DIAGNOSTICS" |
|
|
|
It is critically important for the proper operation of these scripts that you do not manually include any cgroup mount points in |
|
|
|
.IR /etc/fstab . |
|
|
|
After commenting out any extraneous cgroup entries in |
|
|
|
.IR /etc/fstab , |
|
|
|
you should either reboot or manually |
|
|
|
.BR umount |
|
|
|
them and then run |
|
|
|
.BR cgroupfs-mount |
|
|
|
again. |
|
|
|
.SH 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. |
