- Outlines how to utilize Replication within Qumulo Core
- Source and target cluster running the same version of Qumulo Core 2.6.6 and above
- Admin privileges required
Note: You can replicate between any models of Qumulo hardware, including HPE.
Replication in Qumulo Core allows contents of a directory to be moved safely and securely to another directory on a target cluster. You can replicate any of the directories on your cluster and copy all of it's content including the metadata, extra attributes, symlinks, users & groups, and hard-links.
Create a Relationship for Replication
- In the Web UI, navigate to the Cluster menu on the Source Cluster and select Replication under the Configurations section in the dropdown
- Click the Create Relationship button
- Note that you can have up to 100 relationships per source cluster
- Fill in the following fields:
- Source Directory: source of data to be replicated
- Target Directory: target location of replicated data
- Target Address: one of the IPs (preferably floating IP) that target cluster uses
- Port Number: select the default port option
- For custom port configuration, reach out to Qumulo Care for additional information
- Click Save to create a directory relationship. You can now manage the directory relationship on the replication page.
- On the the Target cluster, authorize the directory relationship.
- Until the target cluster is authorized, the directory relationship status will display as Awaiting Authorization on the Source cluster.
Managing Replication and Directory Relationships
- Click the Replicate button on the UI of the source to cluster to manually trigger replication. Keep in mind that each trigger only replicates one time.
- View the Status of Replications, including Finished and Failed, in the directory relationship listing
- If the Replication process encounters an issue and stops for any reason, an error message will display in the Status column.
- Remove a directory relationship by selecting the trash icon
- Attempting to upgrade Qumulo Core while a replication job is running will cause the job to fail. Once both clusters return to a state where replication is possible (same version) replication can start over. Please wait until after the replication job completes to perform any upgrades.
- At the beginning of a Replication job, a snapshot is created for the directory. The old snapshot is programmatically deleted when it is no longer needed.
- There will be one reference snapshot used for replication on the cluster at all times. Admins can view the snapshot(s) used for replication along with other policy-based snapshots.
- Target directory permissions will be updated from read/write to read-only when a replication relationship is created. If the relationship is deleted, the permissions will revert to read/write automatically.
You should now be able to successfully configure and manage Replication in Qumulo Core
