    RolandK replied to the thread MDRAID & O_DIRECT.
    yes, you are right, chances ar low, but i'm not not sure if we should really call it "over engineered" to check boot env for disk issues and to have "zfs|btrfs scrub" equivalent for bootenv. for all those who worry, here are some ideas how check...

    RolandK replied to the thread MDRAID & O_DIRECT.
    yes, but while zfs is getting regular scrub, silent bitrot could indeed happen on partition1+2 on system which is rarely getting touched/updated. such issue will hit you when you don't expect it. chances are low indeed, but the sectors of...

    RolandK reacted to t.lamprecht's post in the thread MDRAID & O_DIRECT with Like Like.
    We explicitly mirror the UEFI partitions outside of ZFS though. And not noticing with many months of uptime means one did not apply any updates for the same period of time, as else IO errors on setting up a new kernel there would get noticed, and...

    RolandK replied to the thread New Windows VM Startup Recovery.
    it seems newly created qcow2 on lvm do not initialize the storage with zero but assume the storage is all zero. so you provide the same data to the qcow2 on re-adding which was there before. try deleting the windows vm and before recreating...

    clearing nvram via setting jumper on mainboard also solved this problem for me on dell r620

    RolandK replied to the thread QCOW2 on ZFS, but over NFS?.
    >So with a local ZFS, and VM RAW disks, you can make use of the native ZFS snapshot feature. Which is (unlike QCOW I believe) instant. yes, but without fs-freeze from the guest agent and thus most likely having worse consistency

    RolandK reacted to Chris's post in the thread proxmox-backup-client more verbose to print whats being backed up ? with Like Like.
    Yes, there is currently no such flag, please add this to https://bugzilla.proxmox.com/show_bug.cgi?id=7024, these can be tackled at once IMO.

    RolandK replied to the thread QCOW2 on ZFS, but over NFS?.
    @IsThisThingOn , for me the button is greyed out when the VM has a raw file. do you refer to "Snapshots as Volume-Chain" are a technology preview feature here ?

    >In general, you should not use QCOW2 in combination with ZFS. >ZFS does all you need already, even better than QCOW. and how will you do snapshots with RAW files ?

    RolandK posted the thread proxmox-backup-client more verbose to print whats being backed up ? in Proxmox Backup: Installation and configuration.
    hello, i am missing some commandline option for proxmox-backup-client to see which files being backed up, i.e. some "more verbose mode" i know about PBS_LOG , but that's neither seems documented in the manpage, nor in the pbs wiki. and it also...

    RolandK reacted to noPa$$word's post in the thread Fehler mit Docker Container nach Linux update with Like Like.
    @RolandK Nur als Hinweis: Mit Formulierungen wie ‚bis es der letzte Horst begriffen hat‘ wirkt der Ton schnell herablassend. Sachlich lässt sich das Thema sicher genauso gut — oder sogar besser — diskutieren, ohne andere abzuwerten. Vielleicht...

    Danke für die Unterstützung Roland und den Link. "Toll" finde ich dass in den Kommentaren unsere Argumentation als "toxisch" outgecalled wird. Ich finde es ja viel toxischer Leute ohne Not in solche Fallstricke laufen zu lassen. Besonders lustig...

    ist halt so - wenn du selber scheisse baust, ist es einfach jemand anderen zu blamen bzw. dir die realtität passend zurechtzubiegen, anstatt zu reflektieren oder zurückzuruden. in unserer gesellschaft hat man damit sogar zunehmend erfolg -...

    nein, wollt ich damit nicht sagen. nur sollte man sich halt nicht nur über solche selbsternannten youtube- oder read-my-tutorial-on-my-blog-profeten bilden sondern auch mal in die hersteller doku wälzen oder ins hersteller forum gucken. ich...
