VME v8.0.8 - Cluster using CEPH with local storage

I'm deploying a 3 node cluster for a POC. I have the VME Applaince v8.0.8 installed & VME Manager installed & initilized.

I'm using local install disks for the storage. I will be configuring CEPH for the disks.

I've reviewed Infrastructure > Storage n the following url for info, but do not find any instructions for configuring CEPH:
https://support.hpe.com/hpesc/public/docDisplay?docId=sd00006560en_us&page=GUID-4885ECA7-94F5-481E-A2FE-A433FAA899C8.html

Also when creating a cluster select hyperconverged infrastructure (HCI) LAYOUT for CEPH
https://hpevm-docs.morpheusdata.com/en/latest/infrastructure/clusters/mvm.html?highlight=ceph#provisioning-the-cluster


Where can I find on configuring CEPH for each node & the cluster?

for the Cluster type, I'll use the HVM 1.2 HCI Ceph Cluster on HVM/Ubuntu 24.04.

Hello.
This is as far as I know, but just for reference.

1. Example Cluster Deployment
https://support.hpe.com/hpesc/public/docDisplay?docId=sd00006560en_us&page=GUID-CDB73B95-18B8-4A10-A09C-4176EE11497D.html#ariaid-title1
→It seems to include information on how to specify "DATA DEVICE."

2. Provisioning the Cluster
https://support.hpe.com/hpesc/public/docDisplay?docId=sd00006560en_us&page=GUID-9886AD4A-5C64-4E09-A106-B14419362757.html#ariaid-title1
→It seems to include an example of an HCI layout.
It says "only one device" here, but "1" lists a way to specify multiple devices, so perhaps the documentation hasn't kept up with the updates. (I guess)

This is a machine translation, so I apologize if it's difficult to understand.

You do not have to set up the ceph cluster yourself. This will all be done when you create a HVM cluster with the HCI layout.
3 things are required:
A dedicated network interface/bond for storage traffic. It needs to exist on all your hosts and need to have an IP. It can be be some non-routable network. As long as all hosts can ping each other on that storage network.

You need to have at least 3 hosts to create a ceph cluster

All hosts need to have some raw disks, unformatted. All hosts need to have the same number of disks and those disks need to have the same /dev/.... names on all hosts. Check with 'lsblk'.


During HCI cluster setup, you provide those /dev/... names. Comma separated.
You also provide the interface for you storage network.

All the rest will be done during cluster creation.

Once done, check status on hosts with 'ceph status' or similar ceph commands.

Last note: make sure NTP is configured on all hosts upfront.

Docs need an update. We support more than 1 date disk in ceph cluster.
