Configuring NFS Configuring storage settings
The share you configure and its parameters appear in the list of shares on the page.
5. Click Add to apply your changes to the running configuration.
Pin Export Optionally, enable data pinning on the share. Select Yes or No from the drop-down list
to specify whether the NFS export should be pinned. Share pinning enables the share to
always contain data that is available to the AltaVault locally without fetching it from the
cloud. You can pin NFS exports only at the time of share creation. Existing unpinned
shares cannot be pinned.
Once a share is pinned, unpinning of that share can be performed via CLI and requires
optimization service to be offline. Unpinning a share can be a time-consuming
operation. Unpinning a share does not result in erasing the previously pinned data. After
unpinning, the previously pinned data becomes available for eviction.
You cannot change this option after the NFS export is created.
Early Eviction Specify whether or not data from this share should be assigned a higher priority for
eviction.
If you select yes, data written to this share is eligible for eviction earlier than other data.
Disable Dedupe Specify whether or not data written to this share should be checked for de-duplication.
If you select yes, then the AltaVault will not perform duplication checks on data written
to the share.
Disable Compression Specify whether or not data written to this share should be compressed.
Select yes if your data set is already in a compressed format and will not benefit from
further compression attempts.
Local Path Specify the internal pathname on the AltaVault to which this share writes data.
Comment Enter a comment about the NFS share. You use only alphanumeric characters,
underscores, hyphens, and spaces in this field.
Export Asynchronously Select the check box to export the NFS share asynchronously. Click the icon for the
following information:
Exporting NFS asynchronously forces the server to drop all fsync requests from the
client. It is required to obtain good performance with NFS clients that issue frequent
NFS COMMIT operations, which might degrade the AltaVault performance
significantly. Many UNIX clients often execute NFS COMMIT operations when low on
memory. To understand the circumstances that cause this behavior and to detect and
prevent it, contact your client operating system vendor. The AltaVault automatically
synchronizes any file that is idle for a configurable amount of time. The default value is
10 seconds. Although there is a window of time (after the server responds with success
for an fsync request, and before the data is written to disk), this window is small and
performance benefits are large. NetApp recommends exporting NFS asynchronously.
Allow Specified Clients Specify which clients can connect to the NFS share.
To limit access, specify the client’s IP address and subnet mask.
By default, all clients can access the share, until the first client is client is entered. To
revert to full access after adding a client, specify 0.0.0.0/0 in the Client IP/Network field
IP/Network field.
Allow All Clients Enables all clients connected to the AltaVault system to access the NFS share.
WARNING: Enabling all clients to access the NFS share is not recommended.
Add Adds the export path and client IP address to the AltaVault NFS server.
Remove Selected Select the check box next to the name and click Remove Selected .
