I had an issue with my calamari server, so I built a new one from scratch.
I¹ve been struggling trying to get the new server to start up and see my
ceph cluster. I went so far as to remove salt and diamond from my ceph
nodes and reinstalled again. On my calamari server, it sees the hosts
connect
In my case, I did remove all salt keys. The salt portion of my install is
working. It’s just that the calamari server is not seeing the ceph
cluster.

You could mount /dev/sdb to a filesystem, such as /ceph-disk, and then do this:
ceph-deploy osd create ceph-node1:/ceph-disk
Your journal would be a file doing it this way.

You may be able to use replication. Here is a site showing a good example of
how to set it up. I have not tested replicating within the same datacenter,
but you should just be able to define a new zone within your existing ceph
cluster and replicate to it.
http://cephnotes.ksperis.com/blog/20
1) set up mds server
ceph-deploy mds --overwrite-conf create
2) create filesystem
ceph osd pool create cephfs_data 128
ceph osd pool create cephfs_metadata 16
ceph fs new cephfs cephfs_metadata cephfs_data
ceph fs ls
ceph mds stat
3) mount it!

You might be able to accomplish that with something like dropbox or owncloud

Is it possible to disable the replication of /admin/log and other replication
logs? It seems that This log replication is occupying a lot of time in my
cluster(s). I’d like to only replicate user’s data.
Thanks!

On two different occasions I've had an osd crash and misplace objects when
rapid object deletion has been triggered by discard/trim operations with the
qemu rbd driver. Has anybody else had this kind of trouble? The objects are
still on disk, just not in a place where the osd thinks is valid.
Hello Everyone,
I have a Ceph test cluster doing storage for an OpenStack Grizzly platform
(also testing). Upgrading to 0.67 went fine on the Ceph side with the cluster
showing healthy but suddenly I can't upload images into Glance anymore. The
upload fails and glance-api throws an error:

I use the virtio-scsi driver.

FWIW: I use a qemu 1.4.2 that I built with a debian package upgrade script and
the stock libvirt from raring.

There used to be, can't find it right now. Something like 'ceph osd set pg_num
' then 'ceph osd set pgp_num ' to actually move your data into the
new pg's. I successfully did it several months ago, when bobtail was current.

You must have a quorum or MORE than 50% of your monitors functioning for the
cluster to function. With one of two you only have 50% which isn't enough and
stops i/o.

How fragmented is that file system?

I live migrate all the time using the rbd driver in qemu, no problems. Qemu
will issue a flush as part of the migration so everything is consistent. It's
the right way to use ceph to back vm's. I would strongly recommend against a
network file system approach. You may want to look into format
1. How about enabling trim/discard support in virtio-SCSI and using fstrim?
That might work for you.
4. Well you can mount them rw in multiple vm's with predictably bad results,
so I don't see any reason why you could not specify ro as a mount option and do
ok.
