…ra debugging Heketi offers an additional way to debug troubles in case unmounting a brick of a Gluster volume fails. This is a problem that is not observed often or consistently. However debugging the issue is difficult as open file descriptors can get closed at a later point, showing no trace of the origin of the failure. By setting the HEKETI_DEBUG_UMOUNT_FAILURES variable to "true", additional information will be available in the logs of the Heketi pod.
