v0.0.3
Release date: 2023-09-25
New features
1. Support OpenWrt LuCI web interface
Using the LuCI web interface, you can easily manage Cluster Box and node devices, including checking system and node status, modifying configurations, and updating firmware.
2. Support web-based firmware flashing
Compared to firmware update over TFTP or serial port, web-based firmware updates are more intuitive and simplified. For details, see Flash firmware of the control board.
3. Support PCIe virtual NIC driver, allowing mounting up to four Blade 3 boards simultaneously
Cluster Box is a high-performance, high-reliability cluster consisting of up to four Blade 3 boards. It implements load balancing, failover, and disaster recovery for guaranteed system reliability and efficiency.
- High performance: Parallel computing allows faster computing speed and higher processing capability.
- Strong scalability: You can mount up to four Blade 3 boards to meet service needs.
- Cost effectiveness: Compared with a single server, a cluster server better utilizes hardware resources and reduces costs.
4. Support node control and status query by running nodectl commands
You can run nodectl commands to manage Blade 3 nodes, specifically:
- nodectl list: List active nodes.
- nodectl poweron/off: Power on or power off nodes.
- nodectl reboot: Reboot nodes.
- nodectl console: Enter the console of a node.
To obtain a complete list of supported nodectl commands and how to use them, see Basic Cluster Box Operations and Commands.
Known issues
1. Blade 3 node 1 cannot communicate with Blade 3 node 3
Reason: The node configuration is incorrect.
Workaround: Modify the configuration of the miop_nodes.txt file. Specifically:
Step 1. Log in to Cluster Box using SSH.
Step 2. Open the /etc/miop_nodes.txt file and edit the file as follows:
6=0
5=1
3=2
4=3Step 3. Save the setting and try communication between Blade 3 nodes again.
2. Cluster Box does not support hot-plug of Blade 3 through the PCIe interface
Reason: N/A
Workaround: N/A
3. The PCIe driver crashes when iperf measures network bandwidth between communicating Blade 3 nodes.
Reason: The PCIe driver has a bug that is being fixed.
Workaround: Avoid using the iperf tool.
