Hi ,all
I use ceph-deploy to deploy a cluster(quick start), but the cluster name is
ceph, Where can I
specify the cluster name in the quick start steps?

Hi，
Thanks for your reply.
I found there is a file ~/.cephdeploy.conf
[ceph-deploy-global]
# Overrides for some of ceph-deploy's global flags, like verbosity or cluster
# name
cluster=myclustername
can this way work?

Hi everyone,
I use CephFS in a production environnement now. So far so good.
However, I have a small problem : my ceph status report (sometimes) a
client failing to respond to cache pressure, but this client is
disconnected since last week. The ceph-fuse on this server was stopped
(willingly).
Hi Thomas,
Is the warning appearing and disappearing if you run ceph status in
quick succession? This might be a symptom of
http://tracker.ceph.com/issues/10151, which will be fixed in the next
development release. If the warning is not oscillating on and off
when you run ceph status
Hi John,
Yes, it oscillates.
It really looks like what you have in the bug report, but with a ghost
client.
I'll wait for the next release then.
Thank you !

I've found that it helps to shut down the osds before shutting down the
host. Especially if the node is also a monitor. It seems that some OSD
shutdown messages get lost while monitors are holding elections.

I see that happen with my really small pools. I have a bunch of RadosGW

ceph -s is not showing any PG's in pool2.

Iam not using rbd pool.

There are two options that can reduce the load on your cluster from
rebuilding so much. If you don't have many OSDs, it would be better to make
the ZFS OSD out first and let the cluster become healthy, then proceed to
remove the OSD and rebuild it.
If you have a lot of OSDs, then the CRUSH

You have a total of 2 OSDs, and 2 disks, right?
The safe method is to mark one OSD out, and wait for the cluster to heal.
Delete, reformat, add it back to the cluster, and wait for the cluster to

I don't think we expose this as an API as such. If you wanted to do
it from within the ceph source you'd use OSDMap::object_locator_to_pg

We do expose a special case of this in the libcephfs API

Hi guys,
Have you looked wiredtiger?
It has LevelDB compatibility API and also has b-tree.

Hi Craig,
but, my concern is why ceph status is not reporting for pool 2 (testPool2
in this case). Whether its not performing scrub or its ceph status report
issue?
Though I have enough of objects in testPool2, scrub is not reporting
active+clean+scrubbing in ceph -s.
