Question on dynamic reservations
Hi, Maybe someone can help me with a problem I'm having. Short version of the question is: Is it possible to use dynamic reservation on statically reserved Mesos agents? The current situation is that we have Mesos cluster which runs many frameworks (aurora, spark, cassandra) and we are developing a custom framework for stateful tasks. Our framework manages stateful tasks for many users. Currently we statically reserved our hardware which has good disks only to be used by our framework (via --resources flag on Mesos Agents). The problem we are facing is that if one stateful task fails we would like to relaunch it on the same host with the same port, cpu, disk and memory. With dynamic reservations we would put a label with task id on a reservation and on failure would just simply reuse the reserved offer. On the other hand with statically reserved Mesos agents we cannot put any labels and so we cannot distinguish offers which should have been reserved for a task and a new offer. This leaves us in the situation that if one stateful task fails and there are new stateful tasks, the new tasks can be scheduled on failed task's Mesos agent, filling it up and taking it's port, cpu and memory. -- Regards Povilas Versockas

MMm... it improved things, but now I get a bunch of: ``` W0113 01:06:24.757287 17811 slave.cpp:5220] Failed to get resource statistics for executor 'riemann-elasticsearch.7fc1bc0b-d92c-11e6-9 367-02426821a225' of framework 20150626-112246-2475462272-5050-5-: Failed to run 'docker -H unix:///var/run/docker.sock inspect me sos-498ff8de-782e-482a-9478-69d3faf5a853-S5.a242fc24-0d32-46e6-af63-299cb82fc01c': exited with status 1; stderr='Error: No such image, container or task: mesos-498ff8de-782e-482a-9478-69d3faf5a853-S5.a242fc24-0d32-46e6-af63-299cb82fc01c ``` and then leaves out a bunch of running containers.

Re: Sigkill while running mesos agent (1.0.1) in docker
If Apache JIRA were up, I'd point you to a JIRA noting the problem with naming docker containers `mesos-*`, as Mesos reserves that prefix (and kills everything it considers "unknown"). As a quick workaround, try setting this flag to false: https://github.com/apache/mesos/blob/1.1.x/src/slave/flags.cpp#L590-L596 On Thu, Jan 12, 2017 at 4:41 PM, Giulio Eulissewrote: > MMm... it seems to die after a long sequence of forks, and mesos itself > seems to be issuing the sigkill.

Re: Sigkill while running mesos agent (1.0.1) in docker
Hi, what the docker command you use to start agents, I remember mesos would try to recover containers which names start with mesos-slave and kill them if could not recover successfully.

Re: Sigkill while running mesos agent (1.0.1) in docker
MMm... it seems to die after a long sequence of forks, and mesos itself seems to be issuing the sigkill. I wonder if it's trying to do some cleanup and it does not realise one of the containers is the agent itself??? Notice I do have `MESOS_DOCKER_MESOS_IMAGE=alisw/mesos-slave:1.0.1` set.
