then you pls suggest how do i implement ha with external storage in proper way

it is not like typical backup i was bothered that vm storage and should be in different hardware apart from servers node that's why

but if i used enterprise ready nas as external storage with redundancy then what is the technical issue i really do not understand

I want to achieve HA setup properly in production env with proxmox, I have lots of vm with db and critical applications currently bbut that are in standaalone servers, as i already stated I am planning live data/vm should be in external storage and nodes will hook up as per requirement in case...

that storage must have RAID with dual controller, you may suggest any alternate option in aspect of shared storage only

can it be like this logically as follows: 1. All running vm's will be on external shared storage. 2. and 3 nodes will only carry proxmox os and external storage will be mount as nfs on three nodes. I was planning to keep my actual vm's/data on to the seperate hardware that's why and may be...

But my confusion is why external shared storage required, to keep the vm's and may be the data will be safe as it is kept on additional hardware in case of server/node failure or is there any specific reason related to HA setup?

But what is the exact technical explanations for requirement of minimum 3 node HA system with shared storage, can anyone explain specifically.

Please suggest your recommendation in respect of storage, as I want to keep user data on separate hardware, and make sure redundancy of that storage hardware as well

Just want to rectify it is 3 node server HA cluster only, I am telling redundancy on external shared storage(ceph) which handle data volume of the vms, and it is a business/office setup

Can you pls explain this part in detail, I am not getting it properly, the way I am currently thinking to implement this setup is as follows It will be a 3 node/server HA cluster, server local storages wiil content NVMe SSD with proxmox and vms (only Os part installed) installed, and external...

My main intention overall is 1. To minimize downtime as much as possible. 2. Redundancy in live data of external storage as our data size is quite high in TB. 3. 0% latency and high IOPS So I was thinking HA with ceph will be ideal solutions for me, correct me if I am wring.

I did not get it exactly you are telling me not to use external storage hardware or something else, I was exactly planning to use one additional storage hardware with ceph filesystem and another storage hardware for redundancy which will hold vm and two storages will be clone to each other, and...

Can u explain the last point more Brief

Fencing device is necessary on this case? If yes what kind of?
