Sunzhe commented on MESOS-5717: ------------------------------- Yes, when starting agent: {{./bin/mesos-agent.sh --master=127.0.0.1:5050 --work_dir=/var/lib/mesos/agent --isolation=gpu/nvidia}} , but appears {{Failed to create a containerizer: Could not create MesosContainerizer: Failed to create isolator 'gpu/nvidia': The 'cgroups/devices' isolator must be enabled in order to use the gpu/devices isolator}}, if i want to enable {{cgroups/devices}}, from explanation of the flag {{--isolation}}, i should {{configure with flag: `--enable-nvidia-gpu-support` to enable}}, but {{--enable-nvidia-gpu-support}} has been removed in Mesos-5630 and can enable this support for all bulds on Linux, That's right? > Can't autodiscovery GPU resources without '--enable-nvidia-gpu-support' and > '--nvidia_gpu_devices' flags > -------------------------------------------------------------------------------------------------------- > > Key: MESOS-5717 > URL: https://issues.apache.org/jira/browse/MESOS-5717 > Project: Mesos > Issue Type: Bug > Environment: RHEL 7.2 > Reporter: Sunzhe > Labels: gpu > Fix For: 1.0.0 > > > Prerequisite: In MESOS\-5257 "By default, with no '\-\-nvidia_gpu_devices' > flag or `gpus` resources flag, the new auto-discovery will simply enumerate > all of the GPUs on the system" and in MESOS\-5630 "removes this > flag(\-\-enable-nvidia-gpu-support) and enables this support for all builds > on Linux." > So, I '../configure' without any flag, and start agent without > '\-\-resources' or '\-\-nvidia_gpu_devices' , but can not discovery GPU > resources, and I also start agent with '\-\-resources' and > '\-\-nvidia_gpu_devices' , it also does not work. > I'm sure the NVIDIA GPUs on my machines are OK, because with > '\-\-enable-nvidia-gpu-support' when './configure' and with '\-\-resources', > '\-\-nvidia_gpu_devices' when starting agents it works well. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
