Description of problem: After a period of time, the freesize value gets set to a large value, like 1200, which is larger than the 500 GB volume backing the block storage. This is problematic because heketi will keep trying to provision block storage to this 500 GB volume since it thinks it has room. Over time the "1200" value grows larger and larger as heketi attempts to provision more blockvolumes to the volume. It takes manual intervention to reset the freesize to 10. To reflect the proper state in gluster. Version-Release number of selected component (if applicable): heketi-6.0.0-7.4.el7rhgs.x86_64 Wed May 30 08:51:41 2018 How reproducible: Customer is able to reproduce this after enough time. Steps to Reproduce: Let heketi provision storage for OpenShift cluster as normal part of it's operations. Eventually the condition will occur and cause any new block volume request to fail because it believes there is more space than actually exists. Actual results: Provisioning new block volumes fails. Expected results: Provisioning new block volume should succeed.
