Just had a quick look. It seems crush could meet the demand,
say, if we have 100 osds, replica_num is 3, then we partition the

can we make it better?
pgp_num is the upper bound of number of OSD combinations, right?
so we can reduce pgp_num to constrain the possible combinations,
and the data loss probability is only dependent on pgp_num,
say, pgp_num/Pn(replica_num) (Since (a, b) and (b, a) are different pgs,
so it is permutation rather than

This patch implements the Swift ACL .rlistings for Radosgw,
it should be seamlessly compatible with earlier version as well
as S3.

HI Yehuda,
Thanks for the answer. We are planning to use the
CEPH_OSD_OP_DELETE to implement
fallocate/hole punching, the details are described in the blueprint
(wiki.ceph.com). Your comments/suggestions
are appreciated.
Regards,
Li Wang
