Я новичок в GlusterFS и пытаюсь развернуть GlusterFS как DaemonSet в новом кластере K8S.
Мой кластер K8S настроен на Bare Metal, и все хост-машины основаны на Debian9.
Я получаю GlusterFS DaemonSet от официального репозитория Kubernetes Incubator, который здесь . Используемое изображение основано на CentOS.
Теперь, когда я разверну DaemonSet, все модули останутся в состоянии ожидания. Когда я делаю описание в Pods, я получаю сбой livelinessProbe / ReadinessProbe со следующими ОШИБКАМИ.
[glusterfspod-6h85 /]# systemctl status glusterd

Затем я запускаю Pod и проверяю логи, и они говорят:

Я что-то пропустил? Раздел volumes в манифесте DaemonSet монтирует тома из hostPath. Должен ли я также развернуть glusterfs-server на моих хост-машинах? Или это проблема несовпадения CentOS / Debian?
