Tomas Barton commented on MESOS-515:
------------------------------------
I've started mesos-slave as a root user, so it's not a problem with writing
permissions (nevertheless /tmp should be writeable for all). I've manually
created /tmp/mesos, restarted slave and now it works. Another log message I was
getting only confirms what you say:
W0620 08:33:14.952710 9958 slave.cpp:2513] Unable to get disk usage: Error
invoking statvfs on '/tmp/mesos': No such file or directory
On 4 slaves the free disk space detection failed, 1 slave worked just fine - I
used the same version of mesos from git, so version 0.13.x. One slave of those
4 slaves had directory /tmp/mesos and was executing tasks the others were never
given a single task, not having tmp directory was probably the reason.
