Hello everyone here,
I just had a try for memory example. And got this error.
Command exited with error message: 5: Failed to open file "/sys/fs/cgroup/memory/memory_only/memory.stale_page_age" for hierarchy 7
I checked around the source, and found memory.stale_page_age file does not exist in neither /sys/fs/cgroup/memory/ and /sys/fs/cgroup/memory/memory_only/.
It is assumed that maybe configuration for this feature is not well enabled in my kernel.
But it seems that the memory_only container can be run well even with this error. Is that right? Or some features are missed?
Do you think it is better to give some messages for successfully created?
