Running Fedora Server with btrfs and Windows Server 2022

[elhanan]

Greetings,
I am new to Proxmox and wanted to try it. Before that, I wanted to clarify if proxmox would be a great choice for a solution I am looking for. Currently, I have Windows Server 2022 running and Fedora Workstation with btrfs running on VMware. The problem I am facing is that whenever there is a power failure and the host OS (Windows Server) shuts down, the Fedora OS corrupts and won't boot, complaining that it couldn't open ctree. Recovering from such an issue is almost impossible, and I have faced this issue frequently. I think the OS won't get time to suspend the guest OS or tell VMware to gracefully shutdown the OS.

Now, I want to explore a Proxmox world to clean the server and install Proxmox and install both Windows Server and Fedora, I am hoping that way I could easily manage both OS without depending on each other. But I want to make sure Proxmox have some features to handle sudden power failures and shutdown not to affect the operating systems running.
So is achievable in Proxmox, I would apperciate any suggestions on this.

Thank you.

maybe you should thing about a UPS, so you server can shutdown gracefully during a power failure? I use a small APC CS500 since years (3rd battery installed last year), which powers my 60W idle proxmox server for around 20minutes ... enough time, to shutdown all VMs and the server.

Proxmox VE is designed for headless server, managed from another computer. There isn't GUI Desktop installed.
Of course no system like power failure.
Not yet corruption here with Proxmox VE default "No cache" for virtual disks.

The problem is that you can't be physically near the server at certain times. even if your UPS lasts for 20 minutes, it doesn't matter unless you have a smart UPS to signal the server to shut down. In my case I only have some basic UPS.

I have experience with a workstation with a web server installed on it and running for 4 Years without a problem, The OS is Fedora Server with XFS; the power fails frequently, but the OS hasn't failed even once in 4 years. But running a Fedora workstation with btrfs, I faced multiple btrfs failures in a few months. Even though UPS and backups are important, neither VMware nor the btrfs file system is doing a good job in recovering from such an issue.

The reason I am looking for proxmox is that proxmox is different from VMware; it doesn't need another host OS to be installed on, therefore, it might help to recover from such issues. I just wanted to confirm.

Thanks for the insight. I am looking forward to using proxmox; I think it would be better in performance compared to VMware.
