Я пытаюсь настроить клиент lustre (документы) внутри док-контейнера, работающего на BlueData. .
Согласно в этом посте я изменил конфигурацию BlueData на каждом рабочем узле и узле контроллера:
$ vi /opt/bluedata/common-install/bd_mgmt/releases/1/sys.config
Я добавил возможность SYS_ADMIN:
{allowed_docker_caps, ["SETPCAP",
"SYS_ADMIN",
...
И перезагрузил хост.
Затем я подготовил кластер Centos 7.x в BlueData:
- CentOS 7.x без предварительно упакованных приложений или программного обеспечения
- Версия изображения: 2.2
- Идентификатор дистрибутива: bluedata/centos7
Затем я подключился к контейнеру Centos:
$ ssh -o StrictHostKeyChecking=no -i /Users/me/.ssh/id_rsa [email protected]
Внутри контейнера я устанавливаю клиент lustre:
sudo yum install \
kernel \
kernel-devel \
kernel-headers \
kernel-abi-whitelists \
kernel-tools \
kernel-tools-libs \
kernel-tools-libs-devel

Однако при попытке загрузить модуль блеска я получаю сообщение об ошибке:

Запуск контейнера как --privileged устранил исходную ошибку, но теперь я столкнулся с новой ошибкой:
[bluedata@bluedata-5 ~]$ sudo dmesg -c
[bluedata@bluedata-5 ~]$ sudo modprobe -v lustre
insmod /lib/modules/3.10.0-957.21.3.el7.x86_64/extra/ptlrpc.ko.xz

В сообщении об ошибке говорилось, что мне нужно настроить сеть, поэтому я попробовал:
[bluedata@bluedata-5 ~]$ sudo modprobe lnet
[bluedata@bluedata-5 ~]$ sudo lnetctl lnet configure
блеск теперь загружается без ошибок:
[bluedata@bluedata-5 ~]$ sudo modprobe -v lustre
