From 1654dd0cf5ee1827322aca156af7d96d757201c7 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Fri, 6 Nov 2009 21:55:25 -0800 Subject: ceph: make object hash a pg_pool property The object will be hashed to a placement seed (ps) based on the pg_pool's hash function. This allows new hashes to be introduced into an existing object store, or selection of a hash appropriate to the objects that will be stored in a particular pool.
