Hello
I have a cluster, (Nautilus 14.2.4) where one pool I'd like to keep on a
dedicated OSDs. So I setup a rule that covers *3* dedicated OSDs (using
device classes) and assigned it to pool with replication factor *3*. Only
10% PGs were assigned and rebalanced, where rest of them stuck in
*undersized* state.
What mechanism prevents CRUSH algorithm to assign the same set of OSDs to
all PGs in a pool? How can I control it?
