Doc Type: Bug Fix
Doc Text:
Heketi can automatically create a new block hosting volume even when there was insufficient disk space on existing block hosting volume. Previously, if more than one request for block volumes were received concurrently Heketi might create more block hosting volumes than necessary. With this update, Heketi no longer allows clients to automatically trigger the creation of extra block hosting volumes when another request is already creating a block hosting volume.

Description Nitin Goyal 2018-07-24 11:02:00 UTC 
Description of problem:
heketi is creating separate block hosting volumes for every block device. Because of this issue storage is also got full.

I had 9 block devices which are in pending state (in OCP) and i had 2 block hosting volumes which were all full. So there is no pending space in the existing block hosting volumes for creating new block devices. For some time all those 9 block devices are in pending state, But after some time all were bound with new 6 block hosting volumes.

Version-Release number of selected component (if applicable):
RPM: 7.0.0-4
Container: rhgs-volmanager-rhel7:3.3.1-21

How reproducible:

Steps to Reproduce:
1. Make sure you have one block hosting volume (size 100gb)
2. Create 105 block pvcs with 1gb.
3. 1 to 99 will be in bound state.
4. 100 to 105 will be in pending state.
5. After some time all 101 to 105 will be in bound state with lots of new block hosting volumes


Actual results:
heketi is creating lots of block hosting volumes.

Expected results:
heketi should create only one block hosting volume when existing block hosting volumes got full.
