Unable to mount memory cgroup

I'm attempting to mount the memory cgroup with the following command:

sudo mount -t cgroup none /sys/fs/cgroup/memory -o memory

I get the error:

mount: /sys/fs/cgroup/memory: wrong fs type, bad option, bad superblock on none, missing codepage or helper program, or other error.

I have all the cgroup kernel configuration options enabled and can mount the cpu, cpuset and devices cgroups without issue.

What am I missing?

Operating System: Raspberry Pi OS Lite (64-bit)

Kernel Version: 5.10.95

Solution

  • Enabling memory cgroups and disabling cgroupv2 in the kernel commandline file with cgroup_enable=memory systemd.unified_cgroup_hierarchy=0 resolves the issue.
