    UdoB reacted to powersupport's post in the thread Slow backup of Proxmox VMs with Like Like.
    Hi, This speed is normal for your setup. Backups are slow because: The backup system is running inside a virtual machine The disk is a USB hard drive The storage is going through another device (Raspberry Pi) Backup software does more work...

    Ich würde wie oben erwähnt ZRAM einrichten und bei Bedarf swappiness anpassen. Du kannst deine Theorie ganz einfach testen indem du den SWAP mit swapoff -a deaktivierst. Alles weitere ist bereits verlinkt und gesagt.

    Dass sich möglicherweise die Namen der Netzwerkkarten geändert haben, hast du auf dem Schirm? Dann klappt natürlich - ohne manuelle Nacharbeit - erstmal nix mehr. https://pve.proxmox.com/wiki/Upgrade_from_8_to_9#Network_Interface_Name_Change

    UdoB replied to the thread [SOLVED] VMs shutting down on remaining host when powering off second node in 2-node Proxmox cluster.
    Interesting! Unfortunately I have no idea what happens. Did you install some magic scripts with hidden automatisms? Take a look into the journal. After the fact by simple using journalctl or live on the still-turned-on node in a terminal...

    Check your /etc/hosts and /etc/network/interfaces. Please note that Proxmox does not support DHCP out of the box and it's best to use a static IP address outside the DHCP-range of the router.

    While there are some staff members actively supporting this community-forum (thanks for that!) the recommended way to be more visible to the developers is to put it into the official bug tracker...

    Setze "swappiness" auf Null. https://pve.proxmox.com/wiki/ZFS_on_Linux#zfs_swap - auf derselben Seite wie bereits oben verlinkt. Allerdings würde ich das nicht machen, sondern eine kleine Menge präsent lassen. Das basiert lediglich auf meiner...

    UdoB replied to the thread Hohe SWAP Auslastung.
    Der "übliche Verdächtige" ist natürlich der ZFS ARC. Der belegte "früher" per Default bis zu 50% des RAM. Und da der ARC zwar schrumpfen kann, dies aber nur sehr langsam funktioniert, kam es dann gelegentlich zu Engpässen. Der aktuelle Default...

    UdoB reacted to big_blue's post in the thread hdd performance with Like Like.
    @UdoB Thank you for your feedback. You're absolutely right, ZFS has features that I wouldn't want to do without. But the reduction in speed is so significant that I was hoping to be able to get a little more speed out of it with new hardware or...

    I suggest using the device ID instead of the letters.

    In doubt of the details look into the good ol' man page: man zpool-attach SYNOPSIS zpool attach [-fsw] [-o property=value] pool device new_device ... If the existing device is a mirror or plain device (e.g. specified as "sda"...

    Hi I'm moving from synology to proxmox; so to start I migrated 1HDD to proxmox, set everything up. Now I'd like to move my second drive to proxmox, and both should be mirrors of eachother. So I'm not expanding as I find in most guides. SDA is the...

    I don't do that often but that looks correct to me and the second command shouldn't be needed. ZFS should be smart enough to know which disk is already part of the pool :)

    UdoB reacted to Falk R.'s post in the thread Performance Probleme with Like Like.
    Ich halte das gern simpler, da gibts bei Umgebungen wo es kein oder schlechtes Monitoring gibt, einfach ein Quota auf X TB auf dem Pool. Bei manchen 80% oder auch mal 95%. Ist immer Umgebungsabhängig.

    Noch ein Hinweis, zfs benötigt frei Blöcke, wenn die alle aufgebraucht wurden, kann man sie nicht mehr löschen. Insbesondere, wenn man zfs-auto-snapshot o.a. Tolls verwendet, um automasch ein zfs snapshot zu erstellen, Kann es passieren, dass der...
