Subject [jira] [Commented] (CASSANDRA-7838) Warn user when disks are network/ebs mounted
Date Mon, 15 Sep 2014 13:43:34 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7838?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14133892#comment-14133892
] 

T Jake Luciani commented on CASSANDRA-7838:
-------------------------------------------

Let's come up with another metrics that is a good "Hey you will have performance problems"
check

Ones I can think of.  

    * Swap enabled.
    * High disk latency
    * Check Ulimits are sensible (sigar has a ulimit check I think)

> It would be nice on start-up to use this to warn users if they are running with settings
that will make them sad, like Network drive or EBS on Ec2.
