Description Rachael 2018-07-05 14:02:41 UTC
Description of problem:

On a CNS setup with no block hosting volume, a script was run to create block PVCs with a sleep time of 30 seconds between each create request. It was observed for each block device a new block hosting volume was created, i.e., there were 9 block hosting volumes for 9 block PVCs. However, any subsequent creation of block PVCs used up the space on the existing block hosting volumes.

How reproducible: 1/1


Steps to Reproduce:

1. On a setup without any block hosting volume, create 9 block PVCs with a sleep time of 30s in between
 
2. Wait for the 9 PVCs to be bound

3. Check heketi-cli volume list

Actual results:

9 block hosting volumes get created


Expected results:

There should be only 1 block hosting volume which hosts all the block PVCs
