我可以将单个GCE磁盘的多个分区安装到Pod吗? [英] Can I mount multiple partitions of a single GCE disk to a Pod?

问题描述

我想使用一个 google计算引擎 磁盘，然后将其安装到 Kubernetes Google Container Engine .

I'd like use a single google compute engine disk and mount it to multiple places a Kubernetes Google Container Engine.

我想知道使用persistentVolumeClaim是否可以工作，但是我希望能工作的是能够装入同一磁盘的两个分区:

I'm wondering if using persistentVolumeClaim would work, but what I did expect to work is being able to mount two partitions of the same disk:

  ...
  volumes:
    - name: database
      gcePersistentDisk:
        pdName: dist-1
        fsType: ext4
        partition: 1
        readOnly: true
    - name: media
      gcePersistentDisk:
        pdName: disk-1
        fsType: ext4
        partition: 2
        readOnly: true

分别安装它们中的任何一个都可以，但是尝试同时安装它们会出现错误:

Mounting either of them separately works, but trying to mount both gives an error:

FailedMount     Unable to mount volumes for pod "frontend-ni7uf_foo": Could not attach GCE PD "disk-1". Timeout waiting for mount paths to be created.

从技术上讲，我可以在单个实例上手动安装两个分区.

Technically I can manually mount both partitions on a single instance.

我想知道这是否是一个错误，是否还有其他解决方案(除了拥有多个磁盘之外)?

I'm wondering if it's a bug and if there is another solution for that (outside of having multiple disks)?

推荐答案

类似，Google Container Engine在两个方面都要求readOnly:

Looks like it Google Container Engine requires readOnly on both:

containers:
  - volumeMounts:
      - readOnly: true
volumes:
  - gcePersistentDisk:
      readOnly: true
