I have 3 CoreOS nodes running in vagrant. Mesos is run natively (not in
docker containers).
There is 1 master/slave and 2 slaves.
If I ssh into one of my slaves and run free -m, I see:
Total: 2005
Used 1342
Free 662
Shares 273
Buffers 13
Cached 1210
In the mesos web-ui, I see that the slave has 1002 MB of memory to offer.
How is this 1002 MB determined (I am running the masters and slaves with
stock defaults and no customizations)?
Is the 1002MB included in the used memory (1342)? If so, why is the
662MB free? It seems to be a waste and I am sure it should be able to
offer another 500MB making the total 1502MB.
