Should we forget about Ceph as long as we only use 2 nodes and directly use DRBD, and look into ceph again when we need a 3th node?

07.04.2021 · The Issue How many nodes required for ceph to have resilience The Answer A minimum of 3 monitors nodes are recommended for a cluster quorum [1] For ceph on Proxmox VE, the statement is still true. Note: Proxmox VE suggest to have 3 nodes at minimum for Proxmox VE cluster as well. References [1] “Zero … Continue reading "How many nodes …

With Proxmox VE you have the benefit of an easy to use installation wizard for Ceph. Click on one of your cluster nodes and navigate to the Ceph section in the menu tree. If Ceph is not already installed, you will see a prompt offering to do so.

I'm planning on two pools in Ceph: A 3-way replicated pool for more 'active' storage like VMs and applications, and a 4+2 erasure coded pool for colder storage ...

This is for my home lab, and money is a little bit tight unfortunately. I am running a 2-node Proxmox/Ceph hyper-converged setup however when one node is down, the shared Ceph storage is, understandably, down since it cannot keep quorum.

Although in the case of two-node clusters it is recommended to use a third, shared quorum disk partition, Proxmox VE 3.4 allows to build the cluster without it. Let's see how. Note: This is NOT possible for Proxmox VE 4.0 and not intended for any Proxmox VE distributions and the better way is to add at least a third node to get HA. System ...

Two Node Proxmox / Ceph "Cluster". at the moment i run a two hardware node proxmox cluster. The third node is a vm on one of the hosts. Not good, but its fine for now. This Cluster runs on shared storage, a synology nas. But i like to migrate to ceph. Now the problem is, that ceph requrie a third monitoring node.

There are two main reasons for using two separate networks: Performance: when OSD Ceph daemons manage replicas of data on the cluster, network traffic can ...

28.03.2018 · 41. Mar 27, 2018. #3. Minimum for Ceph is 3 nodes but not recomended for production. You should use at least 6 nodes, 2 osd each and an enteprise ssd for bluestore db. Hardware, CPU 1 core for each OSD, 1GB RAM for each 1TB of OSD, 3 gigabit network cards, one for proxmox network, two for ceph network (bond).

Hardware, CPU 1 core for each OSD, 1GB RAM for each 1TB of OSD, 3 gigabit network cards, one for proxmox network, two for ceph network (bond). Do not run VM on thesame server with Ceph / OSD's. For the compute nodes, use minimum, 4 network cards.

Feb 03, 2017 · We are runing a proxmox cluster with ceph as storage. Our Ceph cluster has at this moment 7 nodes, each node with 2 osd (2TB HDD), total of 14 OSD. Some of them has journal on a DC SSD, some of the are using the default journal location on OSD HDD. Software version is, root@ceph07:~# pveversion -v.

If you are going to set two node cluster with High Availability (HA) ... mostly using now is Proxmox cluster with CEPH (3 node HA cluster) ...

Jan 23, 2019 · Hi, how many nodes do you reccomend for a Proxmox Cluster with Ceph (HCI mode)? We would like to start with 4 node with 6 SSD disk each, so will have 6 OSD per node and PVE OS on SATA Dom. The other option is 8 node with the same 6 SSD disk on each. Is fine to start with 4 node? Somebody...

First of all, we need to set up 3 proxmox nodes. ... Install Ceph on all nodes: ... In this case osd.0, osd.1 and osd.2 are SSD disks.
