    Spinning rust or not. The theory about using even numbers on disk for data (exept parity 2 + 2 or 4 + 2 or 6 + 2 or 8 + 2 and so on....), was this an old rumor that ZFS incarnations has worked out or not? Google AI says this is not an issue...

    Hey all, I've battle with this for a while now and trying to find posts and configs I finally nailed it today. I tried everything out there, from the "hidden=1" switch to the KVM=off and no luck. I tested every component and configuration I read...

    Exactly why you optimize those ZFS VDEV numbers when using spinning rust. Hard drives lack IOPS and improvement directly reduces waiting time for tasks to finish. SSDs have so much IOPS that it mostly does not matter. Maybe that is why younger...

    Yea, this was acctualy my new Backup 2 server, that is not in work yet. But both machines are similar. I'm certain its a disk I/O problem. The hosts are running Samsung 1725 disc so its not that. But OK, I have read the cons an pros about the...

    Hallo Zusammen, ich hatte heute ein komisches Phänomen, welches ich so nicht kenne. Ausgangssituation: Win2022 VM mit Disks auf einem local-zfs (Single NVMe - das Risiko Datenverlust ist mir bekannt und hinnehmbar) Disks in der VM als...

    I know this thread is old, but I just had the same problem and if anybody stumbles about it, this was the solution in our case. All two nodes of the cluster and VMs were "unknown state" but everything was running fine. A restart of the pvestatd...

    inresting. so it would seem that the stats written by the kernel in /sys/block/*/stat contains wrong value .. ?

    You could try needrestart: needrestart man page By default, it runs in interactive mode, i.e. if you update from the CLI (apt update && apt full-upgrade), it tells you whether a reboot is necessary, lists all services that need to be restarted...

    From those numbers, I suppose the result is that the disk I/O is the problem...

    There is another old thread about that topic as well as bugzilla entry. https://forum.proxmox.com/threads/feature-request-proxmox-ve-scheduled-tasks.152468/ https://bugzilla.proxmox.com/show_bug.cgi?id=7539

    You could only grant them access to manually execute shutdowns via the UI with VM.PowerMgmt perms on a pool or on individual guests. For the scheduling you'd need to go outside PVE. Either drive the API directly with a token scoped to that same...

    OK, I'm quite confident that I've found and isolated the problem (and will drop it on github soon). So let's start with the analysis. At first, be careful that virtio releases in time are not relevant to the commit dates. I mean that if you see...

    Just an intermediate update: while I'm quite sure that at least my latest Patch 3 is more than competent and production-ready candidate, in the hunt of another WS2025-related problems on PVE I found a whole bunch of another threads about the...

    Virtual machine support is better classified first by CPU architecture rather than by the guest OS itself. At this point, the relevant architectures are x86 and ARM. The next question is whether the guest OS supports the virtual hardware...

    PVE doesn't have a 'supported' list, I am assuming this is a list of VMs you're wanting to export from an existing system like vSphere? You can run essentially any x86-64 OS, so all of those are fine. The OS Type field in PVE isn't a...
