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.

thanks!

by the way, I just deploy Multiple SPDK BlueStore OSD instances per node in ceph 12.0.0,
but still mistake when deploy the secondary osd.
did you succeed to deploy Multiple SPDK BlueStore OSD instances per node?
if yes, could you give me the steps how did you deploy, and the configuration of ceph that you configure?
I know it's very rude, but I need your help!

regards
