    [SOLVED] Problem with GPU Passthrough

    I've been bashing my head against a wall, failing to get this to work, and I just had an epiphany. I've been trying to pass through an old Quadro 2000 card. It's Fermi based. As I understand Fermi boards did not have UEFI support. I'm rolling my eyes at myself right now. I'm going to...

    Hostname Change

    So, I've gone looking in the /etc/pve folder and located both my hostnames there, with a bunch of files under them... What if, at the same time as I edit /etc/hosts and /etc/hostname, I also wipe out the old /etc/pve/omniverse, and rename /etc/pve/proxmox to /etc/pve/omniverse.... And then...

    Hostname Change

    Hey Everyone, I set up my first Proxmox server a decade ago, and when I did so, I somewhat naively named the hostname "proxmox". For obvious reasons this is not ideal. I upgraded it in place for several years until my recent server rebuild when I decided it was time for a fresh install. I...

    Best Practices for Backup and Reinstall of Working Environment?

    Do you know if Proxmox cares about the ZFS ID of the pool, or does it just look at the mountpoint? If I were to completely replace one of the pools, zfs send/recv the data from the old pool to the new pool and then give it the same mount location, would it work or would it complain that it...

    Best Practices for Backup and Reinstall of Working Environment?

    Thank you, appreciate the info! Yeah, I've been managing ZFS pools manually from the command line for over a decade, so that part I have figured out. I think what I will do is this: 1.) Back up all config files from old server 2.) Install fresh copy of Proxmox on new server 3.) Shut down...

    Best Practices for Backup and Reinstall of Working Environment?

    Thank you. I guess once I import the configs, I just need to make sure the ZFS volumes mount in the same place again, and it should "just work"? Or will I need to reimport storage volumes into the PVE system? I'm guessing those are configured in the config.db file as well, so I won't have...

    Best Practices for Backup and Reinstall of Working Environment?

    Hi Everyone, I have a 7.4-3 Proxmox standalone server I have been putting off updating, as I am about to get a new server, and when I do I intend to do a clean install anyway. I use a mix of KVM and LXC, and all of my datastores use ZFS. Are there any guides and/or best practices on how to...

    proxmox on arm64

    That's interesting. I didn't think that would work, considering LXC shares the kernel with the host, and MacOS does not use a Linux kernel.

    [SOLVED] Add ZFS Log and Cache SSDs, what i have to buy and to do?

    Short Answer: No. Long Answer: The different VDEV's used to speed things up (Cache aka L2ARC, SLOG aka dedicated ZIL drive and more recently special allocation class) all take advantage of the underlying drives to do their thing. A cache VDEV - for instance - only make sense if it is faster...

    Additional Questions Re: "ZFS: Switch Legacy-Boot to Proxmox Boot Tool"

    Ugh. UEFI. I hate EFI booting. I don't understand why they couldn't leave well enough alone, something that has been working for decades and replace it with UEFI, some marginally functioning trash. The old way was so simple. It just worked. I have moved some systems of mine to UEFI...

    Additional Questions Re: "ZFS: Switch Legacy-Boot to Proxmox Boot Tool"

    Thank you. That is a good suggestion. I gather I'd probably have to do this from a live disk, or risk problems, but that is doable. Appreciate the suggestion! Right now I am torn between this method, and the one described on the How To for Debian on the OpenZFS page which walks you through...

    Additional Questions Re: "ZFS: Switch Legacy-Boot to Proxmox Boot Tool"

    Hi Everyone, I have a few questions regarding the need to switch to Proxmox Boot Tool for booting from ZFS. I found the need to do this in reading the release notes for PVE 7.x in preparing for my upgrade from 6.4.9. Question 1.) It says the boot will break if I run zpool upgrade on the...

    Migrate Host ZFS Boot "rpool" from MBR to UEFI booting?

    Hey all, I run a standalone Proxmox server which I have been upgrading in place for years. I am currently on 6.x, not having upgraded to 7 yet. It was a clean install on Proxmox 4.2 I believe. When i initially installed it, I set it up to boot from a ZFS mirror of two SATA SSD's using...

    proxmox on arm64

    I am not familiar with the Chinese designs, but I do recall reading a lot of reviews of the Cavium (now Marvell owned) ARMv8 ThunderX2 servers and workstations about two years ago. https://www.servethehome.com/cavium-thunderx2-review-benchmarks-real-arm-server-option/...
