Verify

Prints verification reports for the cluster.

verify balance

Prints a balance report that displays all of the unbalanced endpoints or nodes in the cluster.

rladmin verify balance [ node <ID> ]

The [proxy policy]({{< relref "/operate/rs/databases/configure/proxy-policy#proxy-policies" >}}) determines which nodes or endpoints to report as unbalanced.

A node is unbalanced if:

• all-nodes proxy policy and the node has no endpoint

An endpoint is unbalanced in the following cases:

• single proxy policy and one of the following is true:
  • Shard placement is [sparse]({{< relref "/operate/rs/databases/memory-performance/shard-placement-policy.md#sparse-shard-placement-policy" >}}) and none of the master shards are on the node
  • Shard placement is [dense]({{< relref "/operate/rs/databases/memory-performance/shard-placement-policy.md#dense-shard-placement-policy" >}}) and some master shards are on a different node from the endpoint
• all-master-shards proxy policy and one of the following is true:
  • None of the master shards are on the node
  • Some master shards are on a different node from the endpoint

Parameters

Returns

Returns a table of unbalanced endpoints and nodes in the cluster.

Examples

Verify all nodes:

$ rladmin verify balance       
The table presents all of the unbalanced endpoints/nodes in the cluster
BALANCE:
NODE:ID  DB:ID  NAME  ENDPOINT:ID  PROXY_POLICY  LOCAL SHARDS   TOTAL SHARDS

Verify a specific node:

$ rladmin verify balance node 1
The table presents all of the unbalanced endpoints/nodes in the cluster
BALANCE:
NODE:ID  DB:ID  NAME  ENDPOINT:ID  PROXY_POLICY  LOCAL SHARDS   TOTAL SHARDS

verify rack_aware

Verifies that the cluster complies with the rack awareness policy and reports any discovered rack collisions, if [rack-zone awareness]({{< relref "/operate/rs/clusters/configure/rack-zone-awareness" >}}) is enabled.

rladmin verify rack_aware

Parameters

None

Returns

Returns whether the cluster is rack aware. If rack awareness is enabled, it returns any rack collisions.

Example

$ rladmin verify rack_aware

Cluster policy is not configured for rack awareness.
