URL: https://github.com/apache/incubator-pinot/issues/6704
When installing pinot using the helm chart, the minion immediately goes into
`CrashLoopBackOff`.
Error logs from the minion instance:
```text

## Steps to reproduce
1. Add helm repo:
```bash
helm repo add pinot
https://raw.githubusercontent.com/apache/incubator-pinot/master/kubernetes/helm
```
2. Install pinot chart using the following command and values:
```bash
helm install pinot -f values.yaml pinot/pinot --version 0.2.3
```
```yaml
image:
repository: apachepinot/pinot
tag: 0.6.0
cluster:
name: pinot
```
3. Check on the cluster's state:
```text
$ k get po
NAME READY STATUS RESTARTS AGE
pinot-broker-0 1/1 Running 1 2m15s
pinot-controller-0 1/1 Running 1 2m14s
pinot-minion-0 0/1 CrashLoopBackOff 4 2m14s
pinot-server-0 1/1 Running 0 2m14s
pinot-zookeeper-0 1/1 Running 0 2m15s
```
4. Observe `pinot-minion-0` fail with the following error log from above.
## Workaround
Setting the chart value `minion.dataDir` to some subdirectory of
`minion.persistence.mountPath` fixes the problem:
```yaml
minion:
dataDir: /var/pinot/minion/data/data
```
```
$ k get po
NAME READY STATUS RESTARTS AGE
pinot-broker-0 1/1 Running 1 6m43s
pinot-controller-0 1/1 Running 1 6m42s
pinot-minion-0 1/1 Running 0 114s
pinot-server-0 1/1 Running 0 6m42s
pinot-zookeeper-0 1/1 Running 0 6m43s
```
## Additional information
My cluster is running k8s `v1.20.2` on GCP using CSI.
