> Ozone debug chunkinfo shows incorrect block path for some nodes
> ---------------------------------------------------------------
>
> Key: HDDS-9356
> URL: https://issues.apache.org/jira/browse/HDDS-9356
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone CLI
> Reporter: Jyotirmoy Sinha
> Assignee: Aryan Gupta
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.4.0
>
> Attachments: chunkInfo.patch
>
>
> Steps :
> * Create volume/bucket/key
> * Execute 'ozone debug chunkInfo volume/bucket/key'
> Expected output - Block file path should be correct for all nodes
> Observed output - Block file path is incorrect for one node. All paths are
> same (in same data disks) in all the nodes, but in actual one of the nodes
> have the block path in different data disk
> Console output -
> {code:java}
