从K8S集群外部访问Karbon量

再会

我有几个有关Karbon Clusters上的PV的问题。

  • 是否有一种方法可以访问Kubernetes创建的持久卷，除了从POD内到达卷的量吗？
  • 如果PV已发布状态，我仍然可以访问它而无需再次绑定它吗？

基本上，我想知道Karbon PVS上的数据是否可以通过SSH访问，还是K8S Pods以外的其他内容。如果备份保存在PV上，我可以从群集工作器节点以外的另一个VM访问数据吗？

Hello @KeoNaane<\/user-mention> ,

PVC in Karbon can be backed by 2 types of medium:
* Nutanix Volumes (block-based iSCSI volume groups) with either ext4 or xfs filesystem.
* Nutanix Files (file-based NFS shares)

As such, you can always present the VG, or mount the share, from a different environment, such as another VM on your Nutanix cluster.

If you are using Volumes (the default storage class on a Nutanix Karbon deployed Kubernetes cluster), then make absolutely sure no other VMs or Pod has mounted or is using the VG before you expose it to another VM. Also, make sure you use an OS that can actually read ext4 or xfs. Most Linux distributions can do that. Windows VMs cannot without 3rd party software.

Good day

I have a few questions regarding PVs on Karbon Clusters.<\/p>
  • Is there a way to access Persistent Volumes created by Kubernetes besides getting to it from within the pod the volume is mounted?<\/li>\t
  • If the PV has status Released, can I still be able to access it without having to bind it again?<\/li><\/ul>

    Basically, I want to know if the data on Karbon PVs can be accessed via ssh, or something else other than K8s pods. If backups are saved on a PV, can I access the data from another VM besides the cluster worker nodes?<\/p>","quoteUsername":"KeoNaane","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好 @keonaane，，，，

Karbon中的PVC可以由两种类型的培养基支持：
*带有EXT4或XFS文件系统的Nutanix卷（基于块的ISCSI卷组）。
* nutanix文件（基于文件的NFS共享）

因此，您始终可以从不同的环境中展示VG或安装共享，例如Nutanix群集上的另一个VM。

如果您使用的是卷（Nutanix Karbon部署的Kubernetes群集上的默认存储类），请绝对确保在将其暴露于另一个VM之前，请确保没有其他VM或POD已安装或使用VG。另外，请确保使用实际读取EXT4或XFS的操作系统。大多数Linux分布都可以做到这一点。Windows VM不能没有第三方软件。

此致，
Sylvain Huguet。
