Hi Yuri,
I analyzed the errors from the rbd run at
http://pulpito.ceph.com/loic-2015-01-08_10:36:47-rbd-giant-backports-testing-basic-vps/
and summarized my findings in the description of
http://tracker.ceph.com/issues/10501
It would be great if you could let me know if these look familiar.
Hi Josh,
While looking at errors from a giant (plus backports) run of the RBD suite, I
stumbled upon:
http://tracker.ceph.com/issues/10513
and the error is unclear (at least to me ;-). Would you have an idea ? For
information the backports included are all the pull requests mentionned at
Hi Christoph,
I'll have my production cluster ready around next month,
with a lot more powerfull nodes (each node : 2x10 cores 3,1ghz + 6 ssd intel
s3500).
I'll redo benchmark and I post results as soon as possible.

This converts the rbd driver to use the blk-mq infrastructure. Except
for switching to a per-request work item this is almost mechanical.
This was tested by Alexandre DERUMIER in November, and found to give
him 12 iops, although the only comparism available was an old
3.10 kernel which gave

As generic_make_request() is now able to handle arbitrarily sized bios,
it's no longer necessary for each individual block driver to define its
own -merge_bvec_fn() callback. Remove every invocation completely.

Hi Ceph,
I consolidated the pull request, issues and commits into a report in the
description of http://tracker.ceph.com/issues/10501 to get a better view of the
upcoming v0.87.1 point release. It is broken down into:
* already merged in https://github.com/ceph/ceph/tree/giant
* included and

OK.
I roughly checked the problem, it seems to be the same problem which I
met in RPGBackend, and that is why use op_t.append(local_t) instead of
local_t.append(op_t).
Is there any way to reproduce the problem? So I make a patch for the problem.

I can't get consistent performance with 1 MDS. I have 2 clients create
100,000 files (separate directories) in a CephFS mount. I ran the
experiment 5 times (deleting the pools/fs and restarting the MDS in
between each run). I graphed the metadata throughput (requests per
second):

There's just one bug left afaik:
