BarnA Posted June 21, 2022 Share Posted June 21, 2022 How do I enable the cgroup memory controller on Armbian? I’m trying to control memory usage on my orange pi one using systemd with a unit file as follows: [Service] Slice=influxGroup.slice MemoryAccounting=true MemoryHigh=100M MemorySwapMax=250M The command systemd-cgls confirms that the influxGroup.slice has been created, yet memory is not controlled in line with the parameters in the unit file. I think the issue may be that cgroup memory controller is not enabled. I haven’t done anything to enable it, but I did notice that dmesg appears to indicate an enable statement in the kernel parameters: [ 0.000000] Kernel command line: root=UUID=5446759b-56c9-4877-ad1f-15e43cbb95cc rootwait rootfstype=ext4 console=tty1 console=ttyS0,115200 hdmi.audio=EDID:0 disp.screen0_output_mode=1920x1080p60 panic=10 consoleblank=0 loglevel=1 ubootpart=f22f559a-01 ubootsource=mmc usb-storage.quirks=0x2537:0x1066:u,0x2537:0x1068:u sunxi_ve_mem_reserve=0 sunxi_g2d_mem_reserve=0 sunxi_fb_mem_reserve=16 cgroup_enable=memory swapaccount=1 However /proc/cgroups would indicate (I think) that it is not enabled. #subsys_name hierarchy num_cgroups enabled Cpuset 10 1 1 cpu 3 8 1 cpuacct3 8 1 blkio2 8 1 memory5 28 1 devices9 87 1 freezer6 1 1 net_cls8 1 1 perf_event 11 1 1 net_prio 8 1 1 pids4 90 1 rdma7 1 1 So my broadest question is how do I get the system to do what the unit file asks for, which reduces to (I think) a narrower question of: how do I enable the cgroup memory controller on Armbian? 0 Quote Link to comment Share on other sites More sharing options...
