Description

OSD processes fail when trying to create more than one SPDK-backed OSD on a single node. This is because there is no memory restrictions when initializing the Environment Abstraction Layer (EAL), which causes the first OSD process to use up all the available hugepages in the system, leaving none for the subsequent SPDK processes.
