             Summary: Slaves with RO filesystem shouldn't launch tasks 
requesting disk
                 Key: MESOS-699
                 URL: https://issues.apache.org/jira/browse/MESOS-699
             Project: Mesos
          Issue Type: Bug
            Reporter: Joe Smith
            Priority: Minor


At Twitter, we had a few slave with errors in its hard drive, yet it still sent 
resource offers. Unfortunately, when tasks attempted to start up, the executor 
failed when writing its sandbox, as the disk was RO:

{code}
IOError: [Errno 30] Read-only file system
{code}

It'd be awesome if the slave could detect that and not launch tasks that 
request disk.
