The Settings menu includes cluster-wide settings, license information, and optional NFS configuration.
Cluster Settings
The Settings > Cluster menu option opens a page for managing the configuration of a storage cluster. What appears here and whether it is editable depends on the scope, dynamic state, and is using Platform Server.
Are these all settings? See the Settings Reference, which organizes the settings by scope: Cluster + Chassis (Node). Cluster-wide settings are managed here under Cluster Settings. Node-specific settings are not a part of cluster configuration; if needed, DataCore Support can help access them using SNMP or the Chassis Details page Advanced tab's API tools. (v2.2)
What are "advanced settings"? Advanced settings are those in force for a cluster but are not published in the Settings Reference. Clicking Show advanced settings allows viewing and changing the values for these hidden settings. All are dynamic (see next). (v2.2)
Caution
Do not change the advanced settings except as directed by DataCore Support.
Which are dynamic settings? See the Settings Reference, which shows the SNMP name for each setting that can be changed on a running cluster.
Without Platform Server running, every setting can be changed on demand, except for the non-dynamic settings, which appear as read-only.
With Platform Server running, every setting can be changed on demand, but non-dynamic settings display an icon indicating a reboot is needed.
Here is how to make the best use of the Cluster Settings page:
Descriptions | Mouse over the setting name to see the setting description; refer to the Settings Reference for complete details. | |
|---|---|---|
Writable Values | Settings that can be updated on a running cluster display with an edit box or radio toggle to allow for quick editing. NoteThe cluster configuration file must be updated (on the CSN or wherever it resides) and all storage chassis must be rebooted for new settings to be applied to edit settings not supporting dynamic updates (not Persisted Settings (SNMP)). | |
Custom Values | All customized settings appear in bold for easy identification. This does not apply to settings with no default. | |
Changing Values | Changing any editable settings enables the Save button in the upper right corner. Any in process changes can be returned to the previous saved value by using the Revert button. The page prompts the user to decide to Save, Discard or Go Back if navigating away from the page with unsaved changes: Settings changes propagate in the cluster within 60 seconds once clicking Save. | |
License Settings
The license information used by the cluster is displayed on the License Settings page. Scroll down to see the recently updated date.
Note
The License Settings page requires Legacy Swarm Platform to update the license from the Swarm UI; otherwise, it is read-only.
NFS Settings
SwarmFS is an optional component to support network file sharing. See SwarmFS Export Configuration.
