thanks heaps. 
The idea is actually to use K8s so install postgres with glusterfs as storage manager so in case a POD crashes can start again on another node with the same file systems

Cheers

Hi all. I wonder if I can install/configure postgresql with a distributed file system ...specifically glusterFS? is it supported? Does it work properly. 
the ENV is on Centos 7

Any idea? 

It works and it supports all POSIX semantics. And because of it, it's slow as hell to writes because a FS lock acquired by PostgreSQL has to be replicated to all nodes before being confirmed. If you have a read bound database you should be fine tho.

I have tested it but never put in production, it's useless.
What exactly you want to do?

Flavio
