Thanks for your reply.
I am using 0.72.2 and avoiding cephfs as it is not termed as a
production ready in this version.

documentation of Ceph and observerd that the concept of OID (as an

Hi, I removed one of the monitor in the cluster (having 4 monitors previously),

it a common behavior? Does Ceph need so long to remove the monitor thoroughly?

Hi,
I'm trying to run the ceph_rest_api module as a WSGI application behind
Apache with mod_wsgi but I'm struggling a bit.
Not having used WSGI that much I'm stuck on the .wsgi file. Has anybody
done this before?
I've been reading the Flask [0] and Ceph [1] docs, but it's not clear to

Unfortunately, we didn't start building packages for RHEL6 until
recently, and we would (historically) point CentOS and RHEL (and
Scientific Linux too)

The way around this problem is to specify directly

There are two different modes of accessing the buckets.The upload domain and
the download domain are the same.

Now I want to distinguish them. The reason that I want to do this is:

There is no simultaneous support in ceph-deploy as this is something
that is not needed for users setting up a cluster to try out

However, there have been users that used scripts that can call

Hi all,
I read a lot of emails messages and I am confused because in some public
network in /etc/ceph/ceph.com is reported like :
public_network = a.b.c.d/netmask
in others like :
public network = a.b.c.d/netmask
Does it depend by ceph version ?

Hi,
I am setting up a ceph cluster for some experimentation. The cluster is
setup successfully. But, When I try running rbd map on the host, the kernel

Hi,
I have faced a similar issue. This happens if the ceph disks aren't
purged/cleaned completely. Clear of the contents in the /dev/sdb1 device.
There is a file named ceph_fsid in the disk which would have the old
cluster's fsid. This needs to be deleted for it to work.
Hope it helps.

Hi Shashank,
I think you should use rados -p pool_name ls to list all objects in
pool_name,
if there is a image in pool_name , like this :

I have failover clusters for some aplications. Generally with 2 members

fine with ~ 50k email accounts and my HTTP cluster hosts ~2k sites.

Under normal conditions one OSD on one host is not enough to get a

In practice, it's not a big deal. Just deploy your disks sequentially,
and Ceph will sort it out.
Sure, you'll waste a bit of time watching data copy to a new disk, only
to see it get remapped it to a newer disk. It's a small period of time
relative to how long it's going to take to remap
Yeah, there are a lot of smarts like that which could be added in.
