Huh. We took the 5MB limit from S3, but it definitely is unfortunate in combination with our 4MB chunking. You can change the default slice size using a config option, though. I believe you want to change rgw_obj_stripe_size (default: 4 << 20). There might be some other considerations around the initial 512KB "head" objects, though...Yehuda? -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
