[jira] [Commented] (HDDS-11770) Change default failed volume tolerated to 0

["Ethan Rose (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDDS-11770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17900140#comment-17900140 ] 

Ethan Rose commented on HDDS-11770:
-----------------------------------

We should not make the default behavior that a datanode shuts down on any volume failure, that defeats the purpose of having multiple volumes per node.

> Currently "hdds.datanode.failed.data.volumes.tolerated",  "hdds.datanode.failed.metadata.volumes.tolerated" and "hdds.datanode.failed.db.volumes.tolerated" all have default "-1" value, means unlimited, as long as there is a good volume left. 
> There is a corresponding property in HDFS "dfs.datanode.failed.volumes.tolerated", which default is 0, means any volume failure will cause a datanode to shutdown. 
> It's better to have a more conservative default value than this current unlimited value.
