After the TiDB cluster deployment is completed, the cluster fails to start. The firewall has been turned off in advance, but it times out when starting tiflash.

Check the logs under TiFlash on node 123.

Check if the tiflash process is running on the tiflash node with the command: ps -ef | grep tiflash
If it is not running, check the logs for any errors
/tidb-deploy/tiflash-9000/log/tiflash.log or tiflash_stderr.log

If you have checked everything mentioned by the two experts above and found no anomalies, then check the operating system logs.

CPU issue, system not supported, cancel the TiFlash deployment, mine is the same as yours.

:joy: This issue, I’ve encountered it several times with virtual machine deployments. Just modify the virtual machine settings and it will be resolved. It’s much harder to deal with on a physical machine.
