Discourse - DeviceMapper causing corruption?

[Philip Rhoades]

People,

I had a couple of issues to sort out with installing the Docker 
Discourse app and while that was being done people made these comments:

"Devicemapper is non starter, fails spectacularly under load and causes 
corruption. We block setup if we detect devicemapper. You need aufs or 
another better supported docker filesystem."

- which was not true - it did install without resorting to aufs.

also:

"Redhat team get very upset when we mention that it just does not work 
for us, but release after release they say there are no bugs left, and 
each time we keep seeing Discourse users complain about corruption due 
to device mapper."

Any comments?

Thanks,

Phil.
