v0.67.11 dumpling released

[Sage Weil]

v0.67.11 "Dumpling"
===================

This stable update for Dumpling fixes several important bugs that affect a 
small set of users.

We recommend that all Dumpling users upgrade at their convenience.  If 
none of these issues are affecting your deployment there is no urgency.


Notable Changes
---------------

* common: fix sending dup cluster log items (#9080 Sage Weil)
* doc: several doc updates (Alfredo Deza)
* libcephfs-java: fix build against older JNI headesr (Greg Farnum)
* librados: fix crash in op timeout path (#9362 Matthias Kiefer, Sage Weil)
* librbd: fix crash using clone of flattened image (#8845 Josh Durgin)
* librbd: fix error path cleanup when failing to open image (#8912 Josh Durgin)
* mon: fix crash when adjusting pg_num before any OSDs are added (#9052 
  Sage Weil)
* mon: reduce log noise from paxos (Aanchal Agrawal, Sage Weil)
* osd: allow scrub and snap trim thread pool IO priority to be adjusted 
  (Sage Weil)
* osd: fix mount/remount sync race (#9144 Sage Weil)

Getting Ceph
------------

* Git at git://github.com/ceph/ceph.git
* Tarball at http://ceph.com/download/ceph-0.67.11.tar.gz
* For packages, see http://ceph.com/docs/master/install/get-packages
* For ceph-deploy, see http://ceph.com/docs/master/install/install-ceph-deploy

Sage,

Thanks for the great work! Could you provide any links describing how to 
tune the scrub and snap trim thread pool IO priority? I couldn't find 
these settings in the docs.

IIUC, 0.67.11 does not include the proposed changes to address #9487 or 
#9503, right?

Thanks,
Mike Dawson

It's 

 osd disk thread ioprio class = idle
 osd disk thread ioprio priority = 0

Note that this is a short-term solution; we eventaully want to send all IO 
through the same queue so that we can prioritize things more carefully.  
This setting will most likely go away in the future.

Correct.  That will come later once it's gone through more testing.

Thanks!

I use:

[osd]
  osd disk thread ioprio class = 3
  osd disk thread ioprio priority = 0

You’ll need to use the cfq io scheduler for those to have an effect.

FYI, I can make scrubs generally transparent by also adding:

  osd scrub sleep = .1
  osd scrub chunk max = 5
  osd deep scrub stride = 1048576

Your mileage may vary.

Those didn’t make it.

Cheers, Dan

Sigh.. it looks like the version that went into master and firefly uses 
the string names for classes while the dumpling patch takes the numeric 
ID.  Oops.  You'll need to take some care to adjust this setting when you 
upgrade.

Looks like the packages have partially hit the repo, but at least the 
following are missing:

Failed to fetch 
http://ceph.com/debian-dumpling/pool/main/c/ceph/librbd1_0.67.11-1precise_amd64.deb 
  404  Not Found

Based on the timestamps of the files that made it, it looks like the 
process to publish the packages isn't still in process, but rather 
failed yesterday.

Thanks,

That is odd. I just went ahead and re-pushed the packages and they are
now showing up.

Thanks for letting us know!
