Ok. I will try, thanks.
One further question - does needed manually start /etc/init.d/radosgw all
time when this host have been rebooted? Why it is not part of service ceph
-a start?

Hi All,
I am running the MapReduce wordcount code (on a ceph cluster consisting of
2 VMs) on a data set consisting of 5000 odd files (approx. 10gb size in
total). Periodically, the ceph health says that the mds is
laggy/unresponsive, and I get messages like the following:

Hi guys,
The "librbd: Error listing snapshots: (95) Operation not supported"
issue has been resolved, the root cause is when I deployed the OSD, I
just copy /usr/local/bin/* from MON-MDS node to the OSD, not include the
/usr/lib/rados-classes. So I re-transfer the /usr/lib/rados-classes
folder
Hi,
I'm currently looking into several options on how to use ceph in a small to mid

I've ruled out CephFS as it is sadly not stable enaugh.
Then I went with RBD and different approaches. OCFS2 on RBD did the job well
but had extrem performance issues when two processes where

Hi,
I've been working with a Ceph 0.56.4 setup and I've been seeing some RBD
read performance issues with single processes / threads.
The setup is:

- 9 hosts (4 per OSD)
- 120GB Intel SSD as a journal per host

Varun,
What version of Ceph are you running? Can you confirm that the MDS daemon
(ceph-mds) is still running or has crashed when the MDS becomes
laggy/unresponsive? If it has crashed checked the MDS log for a crash report.
There were a couple Hadoop workloads that caused the MDS to misbehave fo
Hey world,
I know that this question is tricky since it depends on the cluster size
and objects profiles.
For those who are using CephFS, what is your working cache size on your
cluster? What problems have you encountered with this configuration?
And for InkTank, do you have any recommendation o

Dear all
I use ceph 0.56.4 - CentOS 6.3 up kernel 3.8.8-1.el6.elrepo.x86_64.
I use multiple versions of the kernel, but I still encountering status:

libceph: osd3 172.30.33.2:6810 socket error on write

Given a partition, is there a command which can be run to validate if
the partition is used as a journal of an OSD and, if so, what OSD it
belongs to?

I'm not sure what the point of running with replication set to 1, but a new
feature adds ceph commands to turn off scrubbing:
Check ceph --help to see if you have a version that has this.
ceph osd set
ceph osd unset
You might want to turn off both kinds of scrubbing.

Mandell,
Not sure if you can start with a partition to see which OSD it belongs
to, but you can start with the OSDs to see what journal partition
belongs to it:
ceph --admin-daemon /var/run/ceph/ceph-osd.0.asok config show | grep
osd_journal | grep -v size

Hi David Zafman
I use Ceph 0.56.4

This command only use in version 0.60 ?
Thanks.

You may need to be root to look at the logs in /var/log/ceph. Turning up
logging is helpful, too. Is the bug reproducible? It'd be great if you could
get a core dump file for the crashed MDS process.
