I have a simple question I hope.
I am moving our VM infrastructure from Xenserver to Proxmox. I only have
one pool that has several RBD images that are mounted in Xen, that pool has
1024 PG's (30OSD's/3x replication).
Question: I would like to create a new pool for Proxmox so I can have a

Hi Michal,
Yes I have considered that, but I felt it was easier to administer the VM's
without having to interact with Ceph every time. I have a another smaller
image that I backup VM configs/data to for cold storage... The VM's are for
internal resources so they are expendable.
I am totally open
Hi Max,
I have a working Xenserver pool using Ceph RBD as a backend.. I got it
working by using the RBDSR plugin here:
https://github.com/mstarikov/rbdsr
I don't have much time, but I just wanted to respond in case it's
helpful... Here is how I got it working:

I ran into an interesting issue last night when I tried to add a second
storage interface. The original 10gb storage interface on the OSD node was
only set at 1500 MTU, so the plan was to bump it to 9000 and configure the
second interface the same way with a diff IP and reboot. Once I did that,

My fsid in ceph.conf is:
fsid = 75d6dba9-2144-47b1-87ef-1fe21d3c58a8
I don't know why the fsid would change or be different. I thought I had a
basic cluster setup, I don't understand what's going wrong.

Hello,
I would like to install OS updates on the ceph cluster and activate a
second 10gb port on the OSD nodes, so I wanted to verify the correct steps
to perform maintenance on the cluster. We are only using rbd to back our
xenserver vm's at this point, and our cluster consists of 3 OSD nodes, 3
ere a way to create rbd images with format 1 without having to convert
from format 2?
Cheers

Hi all,
I need some help yet again... With my cluster backup and running Ceph
10.2.3, I am having problems again mounting an RBD image under Xenserver.
I had this working before I broke everything and started over (previously
on Ceph 10.1), I made sure to set tunables to legacy and disabled

Hi,
Yesterday morning I added two more OSD nodes and changed the crushmap from
disk to node. It looked to me like everything went ok besides some disks
missing that I can re-add later, but the cluster status hasn't changed
since then. Here is the output of ceph -w:
cluster 395fb046-0062-4252
Hi,
I just wanted to get a sanity check if possible, I apologize if my
questions are stupid, I am still new to Ceph and I am feeling uneasy adding
new nodes.
Right now we have one OSD node with 10 OSD disks (plus 2 disks for
caching) and this week we are going to add two more nodes with the same

Hi All,
Is mounting rbd only really supported in Ubuntu? All of our servers are CentOS
7 or RedHat 7 and since they are at Kernel 3.10, I can’t get rbd working. Even
if I use legacy tunables or set tunables to 1/2/3… Nothing will mount the block
device.
The only answer I can find to get this
So just to update, I decided to ditch XenServer and go with Openstack… Thanks
for everyone’s help with this!
Cheers,
Mike

OK, so I am hoping I didn’t miss a configuration or something.

Hi all,
Is there anyone using rbd for xenserver vm storage? I have XenServer 7 and the
latest Ceph, I am looking for the the best way to mount the rbd volume under
XenServer. There is not much recent info out there I have found except for

Hello,
I have a quick and probably dumb question… We would like to use Ceph for our
storage, I was thinking of a cluster with 3 Monitor and OSD nodes. I was
wondering if it was a bad idea to start a Ceph cluster with just one OSD node
(10 OSDs, 2 SSDs), then add more nodes as our budget allows
