Troubleshooting

If the CLI cannot connect to the server and show the version, the reason can be the following:

1. Error while dialing: dial tcp <port_address>: connect: connection refused.

   • Reason 1: The appropriate port is not open and inaccessible for the CLI (by default it is 8000).
   • Reason 2: The xiRAID Opus configuration has been changed. Restart the service.

2. *ERROR* Failed to unlink lock fd for core x, errno: 2

   Reason: The CPU mask parameter has not been configured properly before starting the server. You can reconfigure it as described below.

3. The warning appears during xiRAID Opus installation: *WARNING*: CONFIG: file /.../module.cfg not found

   Reason: The hugemem parameter has not been configured properly before starting the server. You can reconfigure it as described below.

4. To investigate and resolve other issues refer to the logs and use grep to search for ERROR/WARNING messages. These logs can be located in the /var/log/syslog file by searching for the keyword "spdk" in lowercase.
