Hi, without having checked the tracker, does anyone have an explanation why the size parameter is not applied when creating a pool via CLI? According to the help output for 'ceph osd pool create -h' you can specify expected_num_objects (btw. I don't understand what impact that has, all I could find was related to filestore OSDs and PG splitting) and then the size: profile>] [<rule>] [<expected_num_objects:int>] [<size:int>] [<pg_num_min:int>] [<pg_num_max: If I specify both parameters, the pool gets its default size according to osd_pool_default_size (this is a single node cluster, hence default size 2): soc9-ceph:~ # ceph osd pool create temp5 4 replicated replicated_rule 0 4 pool 4 'temp5' replicated size 2 min_size 1 crush_rule 0 object_hash rjenkins pg_num 4 pgp_num 4 autoscale_mode off last_change 260 flags hashpspool stripe_width 0 read_balance_score 1.00 I get the same result on a larger test cluster with multiple hosts. Of course I know that I could just set the size afterwards, but is the command broken? Has anyone looked into this? Thanks! Eugen
