У меня проблемы с подключением тома по iSCSI от Kubernetes. Когда я пытаюсь использовать iscisiadm с рабочего узла, он работает. Это то, что я получил из модуля описания kubectl.
Normal Scheduled <unknown> default-scheduler Successfully assigned default/iscsipd to k8s-worker-2
Normal SuccessfulAttachVolume 4m2s attachdetach-controller AttachVolume.Attach succeeded for volume "iscsipd-rw"
Warning FailedMount 119s kubelet, k8s-worker-2 Unable to attach or mount volumes: unmounted volumes=[iscsipd-rw], unattached volumes=[iscsipd-rw default-token-d5glz]: timed out waiting for the condition
Warning FailedMount 105s (x9 over 3m54s) kubelet, k8s-worker-2 MountVolume.WaitForAttach failed for volume "iscsipd-rw" : failed to get any path for iscsi disk, last err seen:iscsi: failed to attach disk: Error: iscsiadm: No records found(exit status 21)
Я просто использую iscsi.yaml файл с сайта kubernetes.io!

ISCSI Target создается на IBM Storwize V7000. Без CHAP.
Я попытался подключиться к iscsiadm с рабочего узла, и он работает.

Кто-нибудь сталкивается с такой же проблемой?
