2. Click the Summary tab.
The NAS Pool Status panel displays the configured size of the NAS pool.
Expand the Size of the NAS Pool
You can increase the size of the NAS pool as your NAS storage space requirements increase, without affecting the services to the clients.
However, you cannot decrease the size of the NAS pool.
Prerequisites
The Storage Centers must have enough capacity to allocate more storage space to the FluidFS cluster.
The maximum size of the NAS pool is:
• 2 PB with one Storage Center
• 4 PB with two Storage Centers
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the Summary tab.
3. In the right pane, click Actions → Storage Centers → Expand NAS Pool. The Expand NAS Pool dialog box opens.
4. In the NAS Pool Size field, type a new size for the NAS pool in gigabytes (GB) or terabytes (TB).
NOTE: The new size is bound by the size displayed in the Minimum New Size field and the Maximum New Size field.
5. Click OK. If the container has more than one storage type, a drop-down list will appear.
6. From the Storage Type drop-down list, select the type of storage pool, which includes a single data page size and a specified
redundancy level.
7. Click OK.
The Expand NAS Pool dialog box displays the status of the process.
Set the Metadata Tier
Metadata tiering provides the ability to store data and metadata in different storage tiers or LUNs. Metadata tiering allows storing of
metadata items on faster disks, benefiting workloads which are metadata-oriented but require low-cost disks for most of their data. This
feature is disabled by default, and can be enabled at any time during system operation. Metadata tiering is disabled when the system is
updated from an older version of the firmware.
About this task
When creating or expanding a NAS pool, administrators can select the percentage of the FluidFS NAS pool capacity to be allocated for the
metadata tier. For example, High Priority (Tier 1) stores approximately 12.5 percent of the storage for FluidFS in the metadata tier whereas
Low Priority (Tier 3) stores approximately 3 percent of the storage for FluidFS in the metadata tier.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the NAS Pool tab.
3. In the Storage Subsystems panel, click Change Storage Profile.
The Select Storage Profile window opens.
4. Select a storage profile and NAS pool percentage to allocate for metadata.
5. Click OK.
Enable or Disable the NAS Pool Used Space Alert
You can enable or disable an alert that is triggered when a specified percentage of the NAS pool space has been used.
Steps
1. In the Storage view, select a FluidFS cluster.
