HA with 2 local storage

[jebo1]

Hi,

I want activate a HA technology and create a cluster witth 2 servers PVE.
But, for that, it is necessary to have a SAN/NAS connected to the PVE Servers

Question :
Is It possible to have a local storage on every serveurs (same size) and activate HA despite all.

Thanks for your answers.

Not possible with pure local storage, as it does not have any inbuilt replication between the two local storages.

Few options.

1/ HA at the application level with 2 VM's one on each node.
2/ Use CEPH or another replicated storage system across the two nodes.

Thanks for tour help.
I can't create a cluster with my local storage with 2 PVE.
So, it's normal ?

A cluster needs 3 servers, so your need a small 3rd server with Proxmox installed.

OK, finally, go to CEPH Server on 3 servers.
Testing in progress ...

Thanks again

Cluster is OK.
But, how install CEPH Server without internet connection ?
Command "pveceph install" can't connect to git.ceph.com (Of course !)
I tried to connect on this website (from another PC with Internet) but how to recover a good file for PVE ?

Thanks
