Fixed In Version: heketi-3.1.0-10

Previously, Heketi used 4GB as the default minimum brick size which caused the minimum volume size also to be 4GB. With this release, the minimum brick size is 1GB and volumes as small as 1GB can be created.

Description krishnaram Karthick 2016-12-21 07:14:07 UTC 
Description of problem:
Heketi currently has a minimum volume size restriction of 3.5 GB, which is quite high. we have seen cases where customer setups use 1GB volumes for pods. CNS won't be able to cater the needs of such cases unless the size of the volume is reduced to a lower value from the current one. Hence, this min vol size restriction should be reduced to at least 1Gb from 3.5GB.

Version-Release number of selected component (if applicable):
heketi-3.1.0-3.el7rhgs.x86_64
