Hi, I just tried to upgrade mesos from 0.24.1 to 0.25.0. Mesos runs in a docker container. The mesos-slave now fails with the following :
[root@f57993198000 bin]# mesos-slave --master=zk://localhost:2181/mesos --work_dir=/var/lib/mesos I1014 17:14:54.831189 443 main.cpp:185] Build: 2015-10-12 20:59:01 by root I1014 17:14:54.831318 443 main.cpp:187] Version: 0.25.0 I1014 17:14:54.831346 443 main.cpp:190] Git tag: 0.25.0 I1014 17:14:54.831372 443 main.cpp:194] Git SHA: 2dd7f7ee115fe00b8e098b0a10762a4fa8f4600f I1014 17:14:54.831583 443 containerizer.cpp:143] Using isolation: posix/cpu,posix/mem,filesystem/posix Failed to create a containerizer: Could not create MesosContainerizer: Failed to create launcher: Failed to create Linux launcher: Failed to mount cgroups hierarchy at '/sys/fs/cgroup/freezer': 'freezer' is already attached to another hierarchy I tried both on Ubuntu 14.04 and Centos 7.1, same results. Running mesos 0.25.0 on a normal Linux (not docker container) runs fine. Any ideas ? thanks, Harry
