             Summary: Invalid entries in /proc/self/mountinfo when using persistent storage
                 Key: MESOS-6812
                 URL: https://issues.apache.org/jira/browse/MESOS-6812
             Project: Mesos
          Issue Type: Bug
    Affects Versions: 1.0.1
            Reporter: Mateusz Moneta
            Priority: Minor


Hello,

we use Mesos 1.0.1 on Debian Jessie with Kernel {{4.6.1-1~bpo8+1 (2016-06-14)}} and Docker 1.12.5.

We have the problem that on slaves which run tasks with persistent storages Mesos adds invalid entries to {{/proc/self/mountinfo}}. Example:
{noformat}
79 46 253:5 /lib/mesos/volumes/roles/slave/services_proxy_production_mongo#data#4d7ae497-a0f5-11e6-8a4f-e0db55fde00f /var/lib/mesos/slaves/56e2e372-da8e-47d0-ac25-0f55945c625c-S2/frameworks/fa8eb417-29e3-4640-9405-ab84d2ef9794-0001/executors/services_proxy_production_mongo.4d7ae498-a0f5-11e6-8a4f-e0db55fde00f/runs/f84f2541-7e44-4226-80c6-93f438e50fd5/data rw,relatime shared:28 - ext4 /dev/mapper/main-var rw,data=ordered
{noformat}
This causes many {noformat}
