I have searched and found some references to how to set up an Inventory
file to accommodate OSD nodes with different hardware configurations. I

size and number of HDDs, they have different NVMe drives. Also, for
some reasons the HDDs are enumerated starting from /dev/sdc on the old
nodes, but from /dev/sda on the new. Also, the new nodes will have a
Is there a straightforward way, other than duplicating the devices and
block_db_size values multiple times, to define specific settings once
