Description Damian Wojsław 2018-04-26 12:30:16 UTC 
Description of problem:
Gluster nodes observe 100% CPU load during pv provisioning.
There seems to be some mismatch between actual number of LVM devices and what heketi thinks the number is.

How reproducible:


Steps to Reproduce:
1. Issue PVC
2. Gluster nodes get high load
3. Writes to pods hang

Actual results:
Gluster nodes observe 100% CPU load during pv provisioning. 

Expected results:
PVC gets successfully done. Writes are unaffected.
