    [TUTORIAL] Optimierte LinuxVMs unter Proxmox VE

    Schade! Aber Canonical ändert ja auch gelegentlich die Strategien... (Mein neuestes Ubuntu ist 24.04.4 LTS) Obwohl... hier wird es bereits für "Resolute Raccoon" gelistet: https://packages.ubuntu.com/resolute/linux-virtual ... mit einer Dependency auf "linux-image-7.0.0-10-generic", also kein...

    Backup fails without printing actual error

    Mmmmhh... This specific line: comes from a "Directory" storage with "backup" flag set. In my task logs I can see lines like INFO: creating Proxmox Backup Server archive 'vm/1123/2026-03-23T06:46:30Z' ---- Okay, one step back. How do you initiate the backup process? I am usually preparing...

    Syncing ZFS pools to another machine

    Yes. A snapshot makes sure that the whole dataset has a consistent state. And if that's not clear: only the differences (the modified data) will be transferred. "zfs send/receive" is fast because of this. "rsync" operates on another level, one step up to the file system layer. It is filesystem...

    ZFS: Need help with vdevs & pools across multiple HDDs with different capacity

    That's... not the way ZFS usually works. It needs to have identically sized disks. Of course this is Linux and "anything goes". But any "creative" idea to use all the space will possibly lead to trouble in the future. Manual partitioning and then creating multiple pools with these partitions...

    cross cluster migration with snapshots

    Sorry, I do not use it. I just wanted to make sure you know about its existence ;-)

    cross cluster migration with snapshots

    Yes, there are several scripts out there. Keep in mind that if it does not integrate into PVE it is not visible in the "<vm> --> Snapshot" Gui. Take a look into pve-zsync for an alternative implementation... --> https://pve.proxmox.com/wiki/PVE-zsync

    pct list endless

    You may try to limit the speed of a backup. If I remember correctly this limit affects also the read speed on the source side. Datacenter --> Backup --> Edit:Backup Job --> Advanced --> Bandwidth Limit The other mechanism to reduce stress is to use Fleecing - in the same dialog - but this...

    [TUTORIAL] Optimierte LinuxVMs unter Proxmox VE

    Du hast also eine Ausbildung hinsichtlich "schreiben". Ich - und vermutlich die meisten anderen Nutzer hier - leider nicht. Gute Dokumentation zu erstellen ist ja nicht einfach, oft gibt es einfach viel zu viele zu unterscheidende Fälle, man selber hat aber meist nur eine einzige Situation vor...

    replace harddrive in zfs raid

    The specific pool member (sdb9?) gets (logically) destroyed because the partition table on the "<new device>" get overwritten. From that moment on there is no redundancy. Of course you should update your backups first. You need to follow the guide to get back to a "normal"/documented setup. If...

    mehrere Netzwerkkarten nutzen

    Es ist leider nicht klar erkennbar welche Strategie du verfolgen möchtest. Möglicherweise hast du nur begrenzte Netzwerkkenntnisse, daher schildere ich den einfachesten Ansatz - ohne VLANs und managed Switches etc. Ich verzichte in diesem Beispiel auch auf das normalerweise zu etablierende...

    replace harddrive in zfs raid

    Replacing a drive from where you boot up requires some additional specific steps. For example the partition table is different from a pure ZFS pool member. It is documented here: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_zfs_administration -- "Changing a failed bootable device" /...

    Using PBS with a Unifi NAS ??

    I do not know what "988:988" stands for in your setup - but it is not the usual "backup" id. For me it helped to set the "backup" user as the owner: chown -R backup:backup /mnt/nfs . For an NFS mounted folder with the name "dsa" on a PBS I can see: pbsb:/srv# ls -Al . ; ls -Al dsa total 0...

    Backup fails without printing actual error

    Thanks for posting the log. But... you did not tell us anything about your setup :-( What is the source storage? What is the destination storage? ( https://pbs.proxmox.com/docs/installation.html#recommended-server-system-requirements ) How are PVE and PBS connected? Latency? Do you observe...

    OCFS2(unsupported): Frage zu Belegung

    Disclaimer: ich betreibe nichts entsprechendes. Die koordinierende Instanz innerhalb eines Clusters ist die PVE-middleware, nicht etwa das Target. Ein Cluster weiß aber nichts von dem anderen. Und da hilft vermutlich auch kein PDM. Der ist in dieser Hinsicht ja nicht aktiv eingebunden, um so...

    Age verification is identity verification - archLinux32 banned in Brazil.

    They will forbid to possess a hammer as it can be used by teens and you can kill people with it. Oh, wait..., to sell/own weapons is ok. This is completely off-topic in this forum - no further reply necessary... :-(

    Move backups from disk to disk

    Well... that's not helpful. To get some helpful hints you need to describe your setup, tell us exactly what you a) wanted to do, b) what you actually did and c) which error message you got. If you feel it is a bug it is recommended to go (additionally) over there...

    all backups stop if a node is offline anywhere in the cluster?!

    First check: pvecm status as you need to have Quorum to start VMs - because a backup does start all "turned-off"-VMs in a "pause"-state. (I am not sure for running VMs...) That's not a symptom I can confirm. You should post the actual error-message you get when you are in that situation.
