The next bobtail point release is ready, and it's looking pretty good. This is an important update for the 0.56.x backport series that fixes a number of bugs and several performance issues. All v0.56.x users are encouraged to upgrade. Notable changes since v0.56.1: * osd: snapshot trimming fixes * osd: scrub snapshot metadata * osd: fix osdmap trimming * osd: misc peering fixes * osd: stop heartbeating with peers if internal threads are stuck/hung * osd: PG removal is friendlier to other workloads * osd: fix recovery start delay (was causing very slow recovery) * osd: fix scheduling of explicitly requested scrubs * osd: fix scrub interval config options * osd: improve recovery vs client io tuning * osd: improve 'slow request' warning detail for better diagnosis * osd: default CRUSH map now distributes across hosts, not OSDs * osd: fix crash on 32-bit hosts triggered by librbd clients * librbd: fix error handling when talking to older OSDs * mon: fix a few rare crashes * ceph command: ability to easily adjust CRUSH tunables * radosgw: object copy does not copy source ACLs * rados command: fix omap command usage * sysvinit script: set ulimit -n properly on remote hosts * msgr: fix narrow race with message queuing * fixed compilation on some old distros (e.g., RHEL 5.x) There are a small number of interface changes related to the default CRUSH rule and scrub interval configuration options.
