Smoke Testing the System
There are several things you can do to ensure that your data store is up and fully
functional. You verify your data store using the verify configuration
command in the CLI.
- The
verify configuration
command inspects all the components of the data store. It also checks whether all store services are available. For the available store services, the command also checks for any version or metadata mismatches. The command requires no parameters, and runs in verbose mode, by default. For example:
If the output shows all Storage Nodes and replication nodes as running without any errors, then the data store is configured well and all Storage Nodes are up and active.kv-> verify configuration Verify: starting verification of store mystore based upon topology sequence #2 0 partitions and 1 storage nodes Time: 2023-05-24 10:41:15 UTC Version: 23.1.21 See <hostname>:$KVROOT/mystore/log/mystore_{0..N}.log for progress messages Verify: Shard Status: healthy: 0 writable-degraded: 0 read-only: 0 offline: 0 total: 0 Verify: Admin Status: healthy Verify: Zone [name=Boston id=zn1 type=PRIMARY allowArbiters=false masterAffinity=false] RN Status: online: 0 read-only: 0 offline: 0 Verify: == checking storage node sn1 == Verify: sn1: sn1 has 0 RepNodes and is under its capacity limit of 1 Verify: Storage Node [sn1] on <hostname>: 5000 Zone: [name=Boston id=zn1 type=PRIMARY allowArbiters=false masterAffinity=false] Status: RUNNING Ver: 23.1.21 2023-04-18 21:25:44 UTC Build id: 477e7f102ab4 Edition: Enterprise isMasterBalanced: unknown serviceStartTime: 2023-05-24 10:37:28 UTC Verify: Admin [admin1] Status: RUNNING,MASTER serviceStartTime: 2023-05-24 10:38:21 UTC stateChangeTime: 2023-05-24 10:38:21 UTC availableStorageSize: 999 MB Verification complete, 0 violations, 1 note found.

- Run the ping command as shown below:

If you run into installation problems or want to start over with a new data store, then on every Storage node in the data store:
- Stop the Storage Node using:
java -Xmx64m -Xms64m \ -jar $KVHOME/lib/kvstore.jar stop -root $KVROOT
- Remove the contents of the KVROOT directory:
rm -rf $KVROOT
- Start over with the steps described in Installation Configuration Parameters.
