Erasure Coding Ratio Configuration

The default Erasure Coding configuration comes by default in a cluster. Refer to the following steps for any custom Erasure Coding EC needed in a cluster:

Log in to Swarm Storage UI.
Navigate to Settings > Cluster from the left navigation pane.
Scroll down to the Policy section and update the value for the policy.ecEncoding.

Total number of required nodes are calculated using (k + p) / p formula where k denotes the number of data segments and p denotes parity. Based on this formula, administrators can determine the number of nodes required using the default EC protection level of “node”.

Note

For example, a 4:2 (k:p) encoding yields:

(4 + 2) / 2 = 3 nodes required

Data is still fully protected in the event 1 node out of a 4 node cluster is offline. See Implementing EC Encoding Policy for details.

Next, Create New Tenant, Domain, and Bucket.
