dear cepher,
Today, I use mds to put/get files from ceph storgate cluster as it is
very easy to use for each side of a company.
But ceph mds is not very stable, So my question:
is it possbile to get the file name and contentes from OSD with radosgw
once MDS crash and how ?

Hi,
during recovery testing on a latest firefly with leveldb backend we
found that the OSDs on a selected host may crash at once, leaving
attached backtrace. In other ways, recovery goes more or less smoothly
for hours.
Timestamps shows how the issue is correlated between different
processes on s
It's not stable at Firely for kvstore. But for the master branch, it's
should be no existing/known bug.

Hello Greg and John,
I used the patch on the ceph cluster and tried it again:
/usr/bin/ceph-mds -i th1-mon001 -c /etc/ceph/ceph.conf --cluster ceph
--undump-journal 0 journaldumptgho-mon001
undump journaldumptgho-mon001
start 9483323613 len 134213311
writing header 200.

Hi list,
We're using the object storage in production and billing people based

hourly bandwidth graphs for our clients.
We're having some issues with the API not returning the correct

Bonjour,
Maybe http://ceph.com/docs/giant/rados/troubleshooting/troubleshooting-mon/ can
help ? Joao wrote that a few month ago and it covers a number of scenarios.

The short answer is that when the command is executed for second time,
the MDS needs to truncate the file zero length. The speed of truncate
a file is limited by the OSD speed. (creating file and write data to
the file are asy
Thanks! I'll continue with Apache 2.2 until the next release.

There's an issue in master branch temporarily that makes rbd reads
greater than the cache size hang (if the cache was on). This might be
that. (Jason is working on it: http://tracker.ceph.com/issues/9854)

FWIW the specific fio read problem appears to have started after 0.86
and before commit 42bcabf.

Hi,
Given HDFS is far from ideal for small files, I am examining the
possibility of using Hadoop on top Ceph. I found mainly one online resource
about it https://ceph.com/docs/v0.79/cephfs/hadoop/. I am wondering whether
there is any reference implementation or blog post you are aware of, about

I have a number of PGs which are marked as incomplete. I'm at a loss for how to
go about recovering these PGs and believe they're suffering from the "lost
time" symptom. How do I recover these PGs? I'd settle for sacrificing the "lost
time" and just going with what I've got. I've lost the abilit
No, MDS and RadosGW store their data in different pools. There's no way
for them to access the other's data.
All of the data is stored in RADOS, and can be accessed via the rados CLI.
It's not easy, and you'd probably have to spend a lot of time reading the
source code to do it.

You can deploy multiple RadosGW in a single cluster. You'll need to setup
zones (see http://ceph.com/docs/master/radosgw/federated-config/). Most
people seem to be using zones for geo-replication, but local replication
works even better. Multiple zones don't have to be replicated either. For

It looks like you're running into http://tracker.ceph.com/issues/5699
You're running 0.80.7, which has a fix for that bug. From my reading of
the code, I believe the fix only prevents the issue from occurring. It
doesn't work around or repair bad snapshots created on older versions of
Ceph.

Yeah, looks like it. If I disable the rbd ccahe:
$ tail /etc/ceph/ceph.conf
...
[client]
rbd cache = false
then the 2-4M reads work fine (no invalid reads in valgrind either).
I'll let the fio guys know.
Cheers

Thanks. I found the commit on git and confirms 0.80.7 fixes the issue.
