Subject [jira] [Commented] (AMBARI-10882) Allow NFS mounts to be skipped during agent health check
Date Wed, 20 May 2015 14:34:00 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-10882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14552402#comment-14552402
] 

Dmytro Sen commented on AMBARI-10882:
-------------------------------------

There are two new properties in /etc/ambari-server/conf/ambari.properties

- agent.check.remote.mounts can have values true or false. If false, ambari agent runs "df
-l" to skip remote fs's. Default is true
- agent.check.mounts.timeout timeout in seconds for "df" execution. Default is 0(means no
timeout)

> The 'df' checks traverses the entire fstab (including the automounted user directories).
This causes the timeout for each mounted user directory to reset. And since we are checking
so often (even every few heartbeats), these automounted user directory never unmount.
> Adding the '-l' to the 'df' check, would only parse the local disks, and allow the automounted
user folders to timeout properly.
> This should be a configurable property to skip or not.
