One correction, “source /etc/platform/openrc|grep Platform”, should be “source /etc/platform/openrc; system host-cpu-list controller-0|grep Platform”

 

If you get an error “Can not lock an active controller” then you will need to run a system host-swact command first before you can lock the host. Repeat the same steps for the other controller.

Hi,

 

You must have deployed an All-in-one. The value reflects the number of cores reserved for platform services “source /etc/platform/openrc|grep Platform”. You can allocate more cores to platform using system host-cpu-modify command. A host lock/unlock will be required.

Dear community,

 

we have got starlingx running on bare metal and experience an issue that docker demon claims only 4 cpus out of 32.

 

"docker info" output contains

CPUs: 4

 

"nproc" also returns 4

"nproc --all" returns 32 as expected

 

/usr/lib/systemd/system/docker.service contains

LimitNPROC=infinity
LimitCORE=infinity

 

Where are these limit of 4 set and how can I change them?
