6. Checking Node, Partition, and Overall Database Health
On this page
The next step in troubleshooting your cluster is checking on its overall health.
-
Go to the Studio Hosts and/or Nodes page(s) to ensure nodes are online.
-
Run show-leaves to get the
id
of any offline node.sdb-admin show-leaves
-
Then, bring the node(s) online with start-node.
sdb-admin start-node <node-id>
-
-
Go to the Databases page, and examine the problematic database.
-
Click on the database and check the Partitions tab and make sure everything is online and attached.
-
-
If there are offline or detached partitions, investigate the health of the nodes housing those partitions in Studio.
