[Question]: deploy obcluster failed with error: fail to init server, home path is not empty

[Rcforest]

Question I am trying to deploy a 3-node cluster in localhost, but always failed with the same error:

I have tried to remove all directory mentioned and use sudo permission, the error is still above.

How could I solve the problem?

Environment

• OS Version and CPU Arch(uname -a): Linux localhost.localdomain 3.10.0-1160.102.1.el7.x86_64 oceanbase/oceanbase#1 SMP Tue Oct 17 15:42:21 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
• OB Version(LD_LIBRARY_PATH=../lib:$LD_LIBRARY_PATH ./observer -V):
• obd Version: 2.6.1

1. please don't use 'sudo' as it will use root user's environment to deploy the cluster;
2. Why don't you use the lastest oceanbase-ce?
3. please upload your obd log file and the commands you executed.

[Rcforest]

1. sudo permission is just a try for solving the problem, but it failed.
2. Our experiment requires the specific version of oceanbase-ce.

3. The command is obd cluster deploy cluster-3node -c ob3node.yaml -v

   1. ob3node.yaml

      ob3node.txt (Github don't allow for yaml file, so I modified its suffix.)

   2. obd log

      obd.log

It's a problem of obdeploy. I will transfer it to obdeploy repo.

I was able to successfully deploy within CentOS 7 using your configuration file (after adjusting the production_mode, devname, and capacity configuration items to match my own machine's setup). You can carry out the following steps:

obd cluster destroy {deployname} rm -r /data/homedata/zhd/cluster-server* Redeploy If that doesn't work, you can check the detailed system information by running cat /etc/os-release, and I'll see if I have a machine with a similar environment to reproduce the issue.

Below is my configuration file：

Thanks for answering! We have deployed successfully with another machine.
Maybe there is something wrong with our original machine.
