[jira] [Updated] (HDDS-7142) Recon: Add Erasure Coding Statistics
[ https://issues.apache.org/jira/browse/HDDS-7142?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Attila Doroszlai updated HDDS-7142:
-----------------------------------
Description:
Thought: a new tab page (can be integrated with a "File Browser")
- Lists buckets under volumes. Display the current bucket replication policy: Ratis-3 / RS-6-3-1024k
- Optional filter to search for buckets. and show buckets that have EC enabled
- For keys inside a bucket, show the block status:
* (1) For RATIS-1, show the DN name that has the block.
* (2) For RATIS-3, show the three DN names that carrys the block.
* (3) For EC, show all the DN names that has the striped blocks, and their respective index -- Recon should already have this piece of information because DataNodes are already reporting to the Recon.
- Add a warning indicator if a key/file is under-replicated. e.g. with RATIS-3, when the cluster has less than 3 live blocks; with RS-6-3-1024k, when the cluster has less than 9 live striped blocks
