- What did you do?
when deploy tidb cluster and set tmp-storage-path, tidb deploy success but start faild because of permission denied.
tiup cluster deploy lwt v6.5.5 ./test.yaml -utidb(user_a)
global:
user: "tidb"(user_b)
ssh_port: 22
deploy_dir: "/DATA/disk1/tidb-deploy"
data_dir: "/DATA/disk1/tidb-data"
tidb_servers:
- host: xxx
port: 13309
status_port: 10030
deploy_dir: /DATA/disk1/tidb-deploy/tidb-13309
log_dir: /DATA/disk1/tidb-deploy/tidb-13309/log
config:
tmp-storage-path: /DATA/disk1/lwtmp
deploy_user "tidb" has sudo permissions and can successfully create a directory
but user_b(tidb) mkdir failed.
and sudo user_b(tidb) mkdir success.
[tidb@172-16-120-12 ~]$ sudo mkdir /DATA/disk1/lwtmp

Research direction
Start by reproducing the tiup cluster deploy and tiup cluster start commands with the shown test.yaml, focusing on the tmp-storage-path mkdir step under the deployment user. Trace how TiUP handles directory creation and permissions; done means the cluster starts successfully without the permission-denied error.
