【TiDB Usage Environment】: Production
【TiDB Version】: 5.0-5.2.3
【Architecture Consultation】:
Question: How to change the deployment directory?
Existing cluster, expanding an instance with a new directory, such as tidb, pd, tikv, etc., how to configure it to the new directory?
Tiup configuration:
global:
user: tidb
ssh_port: 22
ssh_type: builtin
deploy_dir: /opt/soft/tidb666/
data_dir: data
os: linux
monitored:
node_exporter_port: 6661
blackbox_exporter_port: 6662
deploy_dir: /opt/soft/tidb37022/monitor-6661
data_dir: /opt/soft/tidb37022/monitor-6661/data/monitor-6661
log_dir: /opt/soft/tidb37022/monitor-6661/log

Want to change /opt/soft to /opt/dba
Directly edit-config:
New topology could not be saved: immutable field changed: global.DeployDir changed from ‘/opt/soft/tidb666/’ to ‘/opt/dba/tidb666/’

Yes, I saw this. I am performing node migration by scaling out and scaling in. This way, there is no need to shut down the cluster, just scale out and scale in directly, right?

Yes, in order to prevent non-standard operations from causing cluster anomalies, you can adjust the deployment path by scaling in and out.

Modulate the deployment path by scaling in and out.

I suggest you don’t make changes. Expanding and shrinking will cause data to move around, resulting in degraded performance.

There is a strong demand now to adjust and relocate machines…
