Es ist mal wieder Zeit ein Proxmox VE Homeserver vorzustellen. Als Basis dient ein * ATX Mainboard ASRock B550 PG Riptide Highlight: - NIC 2.5 Gbit/s, - 6x SATA3, - 1 PCIe 4.0 x16 Slot, 2 PCIe 3.0 x16 Slots, 1 PCIe 3.0 x1 Slot - PCIe 4.0/3.0 x4 NVMe (je nach CPU) Als CPU kommt der sehr...

Hey all, So I have recently inherited an r730 that I would like to move my current r430 into. With this change the entirety of the r430 components (CPUs, RAM, HDDs, PCIE NIC, and RAID controller) would simply be removed from the r430 and into the r730. I assume the transfer should be as easy as...

I ran into a kernel level issue with the latest zfs: https://github.com/openzfs/zfs/issues/18648 (I opened the issue) According to some folks on there the issue is only existent in zfs 2.4.x and downgrading to 2.3.x should be a valid workaround until fixed. I was able to downgrade zfs to...

After being advised to use the remote-migration feature to keep QEMU and LXC templates in sync between our three clusters, I have implemented additional remote-migration tasks in our Ansible playbook which is already capable of creating and deploying the OS templates within our primary cluster...

My only point here is that the term “snapshot” has different meanings, heavily depending on the contextual point-of-view: PVE VM snapshot This is the native Proxmox function. It freezes the current status of a VM. This state can be “unfrozen” later to restore this very status via “rollback”...

Hi all, I have several problems to replace a HD which is handed over by ProxMox to an OpenMediaVault (VM500) which handles the HDs by zfs. When ProxMox (8.4.19) boots, on the console I get the message: Port3: ST12000VN0007-2GS116 S.M.A.R.T Status Bad, Backup and Replace Press F1...

I'm having an issue and can't get my server to boot back to the prompt. Any reboot gives the error [31.621178] PANIC: zfs: rt={spa=(zfspoolname) vdev_guid=1903510110132383870 ms_id=471 ms_allocatable}: removing nonexistent segment from range tree (offset=76c079f6000 size =300000) I have tried...

Hi all, Currently I am running on PVE 9.1 with native MDADM RAID5(3x8 TB disks) looking into prospects for switching to BTRFS or ZFS but every now and then power goes out. At the moment I got 4 TB used out of ~ 16 TB and despite some issues it works awesome. Anyone got experience with ZFS and...

Hi everyone, I created the Proxmox datastores using ZFS in mirror mode; the disk pairs have the same capacity, and almost all the virtual machines I have running on them were migrated from ESXi. I have ZFS replication enabled between two nodes. I was trying to figure out if it’s possible to...

I'm not sure if this is a new problem as I havent tried to remove a CT for some while. But today I wanted to remove a few CTs which are running on a NVME ZFS and all result in "TASK ERROR: zfs error: cannot destroy 'NVME-Pool/subvol-121-disk-0': dataset is busy" Similar behavior on that...

When ProxMox (8.4.19) boots, the following messages are shown on console: Found volume group "svProxHD" using media type lmv2 Found volume group "pve" using media type lmv2 3 logical volume(s) in volume group "svProxHD" now active 6 logical volume(s) in volume group "pve" now active...

Hi everyone :) I've created a 200 TB zpool "tank" on the commandline. Works fine and is reboot-safe. However, it does not show up in the proxmox web-UI (in the left "Datacenter"-tree view). Another zpool "ma1" I've created with the web-UI, shows up nicely. Where does pve UI store which pools...

Hello everyone, first time poster here. I have a ZFS pool that has 878GB Free, with 1.22TB Allocated. I have been trying my best to figure out how to release that free space into the pool itself. Any help would be appreciated, Ill post the details below. I have turned on Autoexpand for it as...

Hello everyone. Within my Proxmox setup i am at a point of questioning the way i have completed. I would like some guidance on the issues and the steps i have taken and how to move within this state to the "correct" / "desired" stability. specifically the zfs share between my ct (ubuntu) lxc...

I have 3 node proxmox cluster with zfs storage and want to setup replication jobs but I have around 30 LXCs and can only setup one by one. I have LXCs in all 3 nodes and I want all LXCs replicated to all nodes. Is there a way of doing this without having to manually add an entry to every node...

Before I waste a bunch of time on this... has anybody either succeeded in doing this in an LXC, or ("expertly") concluded that zfs snapshot automation must be done in the PVE host? I too of course would love to see Proxmox add a feature for dataset snapshot automation ( every M minutes, every H...

Hello, I am looking for guidance on the safest next step for a single-node Proxmox VE host with a mirrored ZFS pool. At first my priority was to preserve data and avoid destructive recovery. That is still preferred. However, at this point I am also open to destructive steps if necessary, as...

The title sums it up, more or less. I'm relatively new to ProxMox and self-hosting in general. I basically want to share NextCloud folders with other LXCs, and think I ran into a case of trying to figure out too many things all at once, and thought I'd ask for advice, just to be safe. I'm...

Ich bin inzwischen am Verzweifeln. Nachdem der Mainboardtausch durch eine Neuinstallation Proxmox wieder zum Leben erweckte, habe ich scheinbar nicht nur mit dem Mainboard ins Klo gegriffen. Mein gebrauchter ASR 8405 verabschiedete sich so alle 3-5 Tage mit SCSI hang...? Nachdem ich wohl alle...

The different names for disks may lead to confusion. I show some different names to specify the "right" device. Why is this important? Well..., the obvious thing is that “zpool create” will destroy the old content. You will lose any data stored on it. And the “classic” names like “sda” may...
