Hi Ghislain, This is indeed strange, the pool exists pool 100 'ecpool' erasure size 3 min_size 2 crush_ruleset 52 object_hash rjenkins pg_num 128 pgp_num 128 last_change 11849 flags hashpspool stripe_width 4096 but ceph pg dump shows no sign of the expected PG (i.e. starting with 100. in the output if I'm not mistaken). Could you create another pool using the same ruleset and check if you see errors in the mon / osd logs when you do so ?
