Hi,

I'm actually using a pve 4.4 ceph cluster with 3 nodes. Everything is working as expected.
I'm wondering how to add another ceph node. Is there a way to do it in the GUI or via cli commands ?

Thanks in advanced !

Hi, thanks :)
I thought it is only used for the initial setup

Code:
pveceph install -version jewel
pveceph init

Executing these commands before or after joining new node to the cluster ?

Hi,

Are these commands still valid on proxmox 5.1 in order to add node(s) and osds ?
Seems that it disappeared on the wiki.

Thanks a lot

Hi,

Thanks but I still cannot see what to do in order to add a new node.
From my understanding :

- Prepare new node
- Join existing cluster
- execute : pveceph install -version luminous
- Then what ?

Thanks again ;)

First of all, what version of Ceph are you running? Luminous requires the addition of manager's, etc. Quite different from "jewel".

Hello, my 3 nodes cluster is running pve 5.1 with ceph luminous.
I just want to add a 4th node and install new osds from it.

Ok, after joining new nodes to the cluster we just have to (on new nodes) :
- pveceph install
- pveceph init

After that, we could add new osds/ mons if we need to.

I also noticed that ceph is working (I mean mounting/migrate vms) without install ceph luminous, because some ceph packages are installed (eg ceph-common) but these packages are related to jewel version.

Hi TwiX,

Do we need to specify the --network option when run the command "pveceph init --network xxx like first time we do it. I am in the midst of add new osd node to the running cluster.

Thanks
