Error: OCI runtime error: crun: writing file `/sys/fs/cgroup/cgroup.subtree_control` invalid argument
cgroup2 doesn't yet support realtime-processes.
maybe we downgrade to the original cgroup?
In your Linux kernel configuration kernel parameters/options, set
systemd.unified_cgroup_hierarchy=0 # .. or 1 actually? just changed and works nowIssue/Cause:
- https://github.com/containers/crun/issues/704
- https://github.com/lxc/lxc/issues/3545
- https://bugs.archlinux.org/task/71560
Earlier workarounds
Temp Workaround 1:
sc --user stop mpd.service
, then podman, then can start mpd (or start as non realtime service).
This worked initially but no longer.Temp Workaround 2:
Assign the Linux kernel configuration following kernel params:
NOTE: grub abstracts kernel params? these params are not available.systemd.unified_cgroup_hierarchy=1 cgroup_enable=cpu cgroup_enable=cpuset cgroup_enable=memory cgroup_memory=1
