Yeah, three of nine OSDs went down but I recreated them, but the pgs
cannot be recovered.
I don't know how to erase all the pgs, so I deleted all the osd pools,
including data and metadata … Now all pgs are active and clean...
I'm not sure if there are more elegant ways to deal with this.

Hi Craig,
Sorry for late response. Somehow missed this mail.
All osds are up and running. There were no specific logs related to this
activity. And, there are no IOs running right now. Few osds were made in and
out ,removed fully and recreated before these pgs coming to this stage.
I had tried
Hi All,
Here are the steps I followed, to get back all pgs to active+clean state. Still
don't know what is the root cause for this pg state.
1. Force create pgs which are in stale+down+peering
2. Stop osd.12
3. Mark osd.12 as lost
4. Start osd.12
5. All pgs were back to active+clean state
Thank
Hi,

my crush tunables are set to bobtail, so I can't go bellow 3.9, I will try 3.12

16 pgs in our ceph cluster are in active+clean+replay state more then one day.
All clients are working fine.
Is this ok?

Karan,
Thanks for the tutorial, great stuff. Please note that in order to get the
graphs working, I had to install ipvsadm and create a symlink from
/sbin/ipvsadm to /usr/bin/ipvsadm (CentOS 6).

Ilya,
I've not used rbd map on older kernels. Just experimenting with rbd map to have
an iscsi and nfs gateway service for hypervisors such as xenserver and vmware.
I've tried it with the latest ubuntu LTS kernel 3.13 I believe and noticed the
issue.
Can you not reproduce the hang tasks when

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.

Hi!
We have an Icehouse system running with librbd based Cinder and Glance
configurations, storing images and volumes in Ceph.
Configuration is (apart from network setup details, of course) by the
book / OpenStack setup guide.
Works very nicely, including regular migration, but live migration of

Can you explain this a little more, Johan? I've never even heard of
ipvsadmin or its facilities before today, and it ought not be required...

I imagine you aren't actually using the data/metadata pool that these
PGs are in, but it's a previously-reported bug we haven't identified:
http://tracker.ceph.com/issues/8758
They should go away if you restart the OSDs that host them (or just
remove those pools), but it's not going to hurt anythin
Looks like the packages have partially hit the repo, but at least the
following are missing:

Thanks Yehuda for your response, much appreciated.
Using the "radosgw-admin object stat" option I was able to reconcile the

replicated to the slave, for these 10 objects I was able to confirm by pulling

Hi,
I have several servers and each server has 4 disks.
Now I am going to setup Ceph on these servers and use all the 4 disks but it
seems one OSD instance can be configured with one backend storage.
So there seems two options to me:
1. Make the 4 disks into a raid0 then setup OSD to use this
Hi James,
the best practice is to set up 1 OSD daemon per physical disk drive.
In your case, each OSD node would hence be 4 OSD daemons using one physical
drive per daemon, and deploying a minimum of 3 servers so each object copy
resides on a separate physical server.

On my ceph cluster osd node . there is a rule to REJECT all.
As per the documentation, added a rule to allow the trafficon the full
