I have some questions. 1. Is there any chance to change default 4MB object size to for example 1MB or less ?? 2. I have create cluster of two mons, and 32 osd (1TB each) on two machines. At this radosgw with apache2 for test. When i putting data from s3 client to rados, everything is ok, but when one of osd is going down all s3 clients going to be freeze for some seconds, before ceph sign this osd as down, and then everything is starting working again wit degraded osd. How can i tune this marking as a down for ms or 0 :) and not for seconds freeze ?? My setup is debian 6.0, kernel 2.6.37.6 x86_64 and ceph version 0.31-10 from stable repo.
