Describe the issue: 
GlusterFS provisioner makes use of Heketi API service. With Heketi, the volume sizes are required to be more than 10Gi, any smaller sizes requested via PVC will end in failure with error 'No space', which can be quite misleading. See issue: https://github.com/heketi/heketi/issues/505

Users need to be advised about this so that they don't run into same problem.

Suggestions for improvement: 

Additional information:
Comment 1 Humble Chirammal 2016-10-19 07:24:51 UTC 
The minimum volume size depends on couple of other parameters like min_brick_size..etc which is a configurable value in server side, so defining a 'minimum volume size' is difficult from the client side.  The error is bit misleading, however we have improved this error and from here on https://github.com/heketi/heketi/pull/472, we should get a proper error message.
Comment 2 Humble Chirammal 2016-10-21 13:46:27 UTC 
I would like to call this as NOT A BUG.
Comment 4 brice 2018-04-24 14:42:22 UTC 
An improved error message works for me. I'll close this BZ.
