Hi,

My issue is very strange..

I have one cluster of 3 physical servers where is installed Proxmox VE 4.4. I installed on each nodes ceph with 'pveceph install -version hammer' command. I have 3 monitors on the different nodes in my cluster.

Each servers have 1 disk of 1TB and an other where is installed proxmox (300GB). So i would like to create OSDs on the disks of 1TB on my ceph cluster. I ran this command : 'pveceph createosd /dev/sdb' on each nodes but in the GUI i can't see osd disks.

/etc/pve/ceph.conf look like this :
Code: 
[global]
    auth client required = cephx
    auth cluster required = cephx
    auth service required = cephx
    cluster network = 10.51.1.0/24
    filestore xattr use omap = true
    fsid = 1897e77f-f5bf-4766-9458-f65227f1ba72
    keyring = /etc/pve/priv/$cluster.$name.keyring
    osd journal size = 5120
    osd pool default min size = 1
    public network = 10.51.1.0/24

[osd]
    keyring = /var/lib/ceph/osd/ceph-$id/keyring

[mon.0]
    host = px-node-1
    mon addr = 10.51.1.11:6789

[mon.2]
    host = px-node-3
    mon addr = 10.51.1.13:6789

[mon.1]
    host = px-node-2
    mon addr = 10.51.1.12:6789

I have not files / folders in /var/lib/ceph/osd . I think it's not normal ..

I have impression that no OSDs disk is created on my cluster, I'm wrong ?

Thanks

Did you do a "apt-get update" then a "apt-get dist-upgrade" before installing ceph?
 
Yes MajorD. I ran update and dist-upgrade before.

----------------------

UP.

Now i've 6 OSDs on my cluster.

When I run 'ceph osd tree --format=json-pretty', I get this result :

Code: 
{ "nodes": [
        { "id": -1,
          "name": "default",
          "type": "root",
          "type_id": 10,
          "children": [
                -2]},

                4]},
        { "id": 4,

  "stray": [
        { "id": 0,
          "name": "osd.0",
          "exists": 1,

          "status": "down",
          "reweight": "0.000000",
          "id": 1,
          "name": "osd.1",
          "exists": 1,
          "type": "osd",
          "type_id": 0,
          "status": "down",
          "reweight": "0.000000",
          "id": 2,
          "name": "osd.2",
          "exists": 1,
          "type": "osd",
          "type_id": 0,
          "status": "down",
          "reweight": "0.000000",
          "id": 3,
          "name": "osd.3",
          "exists": 1,
          "type": "osd",
          "type_id": 0,
          "status": "down",
          "reweight": "0.000000",
          "id": 5,
          "name": "osd.5",
          "exists": 1,
          "type": "osd",
          "type_id": 0,
          "status": "down",
          "reweight": "0.000000"}]}

Code: 
16:07:43 ~ # ceph osd tree                                                   
# id    weight    type name    up/down    reweight
-1    0    root default
0    0    osd.0    down    0

Why have I one OSD in "nodes" section and my other osd in "stray" section ? Moreover their status is display as "down". I don't understand. Someone knows why ?

Thanks
