Nutanix文件3.x-扩展文件服务器存储

Volume groups enable both high availability and scale-out for the file systems. A volume group is a collection of logically related vDisks (or volumes) attached to the guest via iSCSI. When an FSVM is down for maintenance or if a fault occurs, one of the surviving FSVMs takes over volume group ownership and continues servicing requests.<\/p>

\u00a0<\/p>

With the 3.x release of Nutanix Files, volume groups contain 16 virtual disks.<\/strong>
From the 3.2 release of Files onward, all disks in the volume group are available for use by the assigned shares, representing a maximum standard share size of 140 TB<\/strong>.<\/p> <\/blockquote>

\u00a0<\/h3>

Nutanix Files Storage<\/h3>

The initial file system pool created on the volume group uses six of the drives as previously noted and supports 40 TB of data<\/strong><\/p>

Once this file system pool reaches 80 percent space utilisation, Nutanix Files automatically expands it to 80 TB <\/strong>by incorporating another four data disks from the volume group.<\/p>

This expansion process can occur two more times, increasing the file system capacity to 120 TB<\/strong> with the second expansion and 140 TB<\/strong> with the final expansion. Each expansion is triggered at 80 percent space utilisation of the current pool.<\/p>

Monitoring Nutanix Files Space Consumption<\/h3>

File shares can grow at a very fast pace, which is why NCC File server health check periodically checks:<\/strong><\/p>

• File Server usage is nearing 100 percent<\/li>
• Files Container Usage<\/li>
• Storage Pool usage (where the Files Container resides)<\/li> <\/ul>

  Nutanix Files - FileServerSpaceUsageCritical<\/code> alert <\/strong>is generated when Files Storage usage is close to 100 pct<\/strong> or Container usage is greater than 85 pct<\/strong> or Storage pool is greater than 90 pct<\/strong>. So for any of the above scenarios, this critical alert is generated by the file server health_check. When the alert is generated, the file server is marked read-only by marking all shares read-only<\/strong>.<\/p>

  Expanding Nutanix Files Storage<\/h3>

  In case of Nutanix Files storage nearing or at 80percent, one can expand the File Server Size (provided there is enough space in the respective container).\u00a0<\/p>

  To change the storage capacity<\/strong>, enter the new size (in TiBs<\/strong>) in the FILE SERVER SIZE <\/strong>field and Click on Save<\/strong>.<\/p>
