| Doc Text: |
With Red Hat OpenShift Container Storage 3.11 Update 5, if a create block volume operation followed with the delete block volume operation on a given block hosting volume caused tcmu-runner service to crash with SEGV. This is caused due to memory corruption in glusterfs when global memory structures were destroyed and reinitialized as part of glfs_init() and glfs_fini(). As tcmu-runner uses gfapi library, it is the one that will receive SEGV signal. Now, with this update, memory pool management races were fixed in the core glusterfs, hence hereon no crashes will be observed by tcmu-runner or gluster-block daemons.
