algorithm.
[ https://issues.apache.org/jira/browse/MESOS-440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13643413#comment-13643413 ]
Benjamin Mahler commented on MESOS-440:
---------------------------------------
We should be respecting the disk resources allocated to the slave, when deciding how "full" the disk is.
> Allow for headroom in the GC algorithm.

> Key: MESOS-440
> URL: https://issues.apache.org/jira/browse/MESOS-440
> Project: Mesos
> Issue Type: Bug
> Reporter: Benjamin Mahler
> Assignee: Vinod Kone

> On a heavily loaded slave, we don't GC aggressively enough to ensure we keep some headroom.
> This was discovered by Vinod:
> This slave started ~8hours ago, the disk is currently hovering at 95% => max allowed age of ~8 hours.
