Fixed In Version: rhgs-volmanager-container-3.11.5-1 Doc Type: Enhancement
Doc Text:
With this update, a new environment variable HEKETI_LVM_WRAPPER has been added. This environment variable enables Heketi to call a wrapper script inside the RHGS-Server containers to execute LVM commands. This improves stability of LVM initialization and handling of any LVM events during runtime. Race conditions between the LVM stack on the host and inside the container do not occur. Now, the LVM commands are executed through a wrapper script that runs LVM commands on the host instead of inside the container.

Description Raghavendra Talur 2019-11-14 18:37:54 UTC 
Description of problem:
For better synchronization of LVM metadata between the gluster container and the container host, we should execute the commands in the namespace of the host. Wrapper scripts should be available in the container to perform these executions in a different namespace and heketi should call them instead.
