Test HA with central storage

[bond347]

Hello forum members,

I plan to test HA feature in my 3 hosts cluster environment. Read up to achieve HA, i need a central storage as VMs / containers repository.
For a test, i wanted to use my small Qnap storage and share the LUNs via iSCSI.

Hope some experts here can guide me and/or share some articles to complete my testing.

depends how you want to build your cluster. on the end you have 2 possibilities.
1. ceph (replication of VMs to another nodes)
2. own storage (i guess you meant this with central storage) your spof is the storage and the network is the bus system

i got myself a ceph cluster. it just works with the local storage. configure it proper and the cluster is ready to go.
just unplug your server and in 2 mins a recent copy of the VMs of the failed Nodes will start.
works like a charm

Hi Pille99,

Thanks for the pointer on Ceph.

I wanted option #2, whereby having my independent storage box as a central storage.

Hope yourself or other members could share/guide me to setup HA with central storage.

Hi @bond347 ,
There are many resources available on the net:
https://pve.proxmox.com/wiki/Storage:_iSCSI
https://www.wundertech.net/how-to-set-up-iscsi-storage-on-proxmox/

The best way to tackle it is to start the setup and come back with specific technical questions.

Best of luck
