Bill Zhao created MESOS-5923:
--------------------------------

             Summary: Ubuntu 14.04 LTS GPU Isolator "/run" directory is noexec
                 Key: MESOS-5923
                 URL: https://issues.apache.org/jira/browse/MESOS-5923
             Project: Mesos
          Issue Type: Bug
    Affects Versions: 1.0.0
         Environment: Ubuntu 14.04 LTS
            Reporter: Bill Zhao


In Ubuntu 14.04 LTS the mount for /run directory is noexec.  It affect the {{/var/run/mesos/isolators/gpu/nvidia_352.63/bin}}
directory which mesos GPU isolators depended on.

{{bill@billz:/var/run$ mount | grep noexec
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)}}

The /var/run is link to /run:
{{bill@billz:/var$ ll
total 52
drwxr-xr-x 13 root root     4096 May  5 20:00 ./
drwxr-xr-x 27 root root     4096 Jul 14 17:29 ../
lrwxrwxrwx  1 root root        9 May  5 19:50 lock -> /run/lock/
drwxrwxr-x 19 root syslog   4096 Jul 28 08:00 log/
drwxr-xr-x  2 root root     4096 Aug  4  2015 opt/
lrwxrwxrwx  1 root root        4 May  5 19:50 run -> /run/}}

Current the work around is mount without noexec:
{{sudo mount -o remount,exec /run}}
