Hi All,

My Origin cluster is pretty new, and I happen to spot the following log
entry by elasticsearch in kibana (I'm using OpenShift's logging stack):

[2016-08-30 01:44:25,997][INFO ][cluster.routing.allocation.decider]
[Quicksilver] low disk watermark [15%] exceeded on
[t2l6Oz8uT-WS8Fa7S7jzfQ][Quicksilver] free: 1.5gb[11.4%], replicas will not
be assigned to this node

df on the node shows the following:

/dev/mapper/centos_node3-root   14G   13G  1.6G  89% /
......
tmpfs                          7.8G  4.0K  7.8G   1%
/var/lib/origin/openshift.local.volumes/pods/8a2a40e3-5f83-11e6-8b2f-0231a929d7bf/volumes/
kubernetes.io~secret/builder-dockercfg-3z4qk-push

tmpfs                          7.8G   12K  7.8G   1%
/var/lib/origin/openshift.local.volumes/pods/8a2a40e3-5f83-11e6-8b2f-0231a929d7bf/volumes/

tmpfs                          7.8G  4.0K  7.8G   1%
......

This appears to be the case on one of my other nodes as well (with a
slightly different tmpfs size of 5.8G).

Is this normal?
