v0.56.2 released

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.  Please see the full release notes.

You can get v0.56.2 in the usual fashion:

 

Comments: v0.56.2 released

  1. Great! It runs pretty good on our Ubuntu 12.04.1 distro with XFS filesystem. Is your roadmap still uptodate and will 0.59 be released soon? It is stated to be completed in 16 days in the roadmap.
