    Genau dabei helfen Diskussionen wie diese hier. Bleiben wir mal bei Proxmox dann können wir festlegen, dass die Modelle zu einem maßgeblichen Anteil durch eben dieses Forum hier befüttert werden. Daher ist es nicht nur in unserem, sondern...

    UdoB replied to the thread Filesystem choice for consumer SSD.
    Well, the usual reasons against ZFS are a) some higher wearout = the SSD won't last as long as with LVM/ext4 and b) slower performance because of more write-activity. (And no PLP which would allow delaying the actual write...) The required...

    @katti Depending on your requirements on a how long the services can be unavailable and on how much fresh data can be lost, a workaround could be frequent backups to PBS. And restoring to the other cluster when needed). Thanks to "dirty bitmaps"...

    "KI" (es gibt bisher keine künstliche Intelligenz! Es gibt nur Sprachmodelle.) ist gekommen um zu bleiben. Eine Kennzeichnungspflicht erscheint plausibel, ist aber weder mittel- noch langfristig durchsetzbar und vor allem nicht wirklich...

    Ich bitte um eine Diskussion/RFC zu o.g. Thematik. Mittlerweile nehmen die Beiträge welche erkenn- und nachweisbar zu nahezu ausschließlich KI-Content bestehen massiv überhand. Besteht die Möglichkeit dies einzuschränken und/oder eine...

    UdoB replied to the thread Filesystem choice for consumer SSD.
    While I am definitely a ZFS fan there might be situations where LVM (-thin) is the recommended choice. Sadly this might be that rare occasion...

    No, it still doesn't make sense. Proxmox is somehow supposed to know if this was an "intended" shutdown rather than a VM crash, and do something different in that case. And you want "on demand" machines to have high availability? What the heck...

    UdoB reacted to Khensu's post in the thread NICs inoperative in ProxMox with Like Like.
    As my predecessors have already said, your configuration is trying to use the port enp3s0, which no longer exists. You still have enp7s0 and enp8s0. These are down because they do not appear in any network configuration. Either your power outage...

    UdoB replied to the thread NICs inoperative in ProxMox.
    In the first screenshot we see enp7s0 and enp8s0 - being "DOWN", please check the actual cables and the LED on the other end of the cable. In the second screenshot we see you've configured enp3s0. Different names --> it can not work...

    Hi @ajpion , welcome to the forum. The system (Linux or Windows) allows for one default gateway. Any gateway beyond default one are not default by definition and need to be scoped for a particular subnet) destination. If your client and storage...

    Yeah, should work. Personally I do not like scripts (and especially cronjobs) to deny doing its job silently...

    Hi Jonas, after mentioned update (dist-upgrade, not cherry picking that one) network settings are back to "yes/no" and OSD flags have checkboxes. I had and have no console issues at all. Linux guests only, most of them using BIOS and a few...

    UdoB reacted to alexskysilk's post in the thread Best RAID for ZFS in Small Cluster? with Like Like.
    If by redundancy you mean disk fault tolerance, the higher the value after "raidz" the higher the fault tolerance. In practice, raidz2+ (never use single parity raidz unless prepared to lose the pool at any time) performance= striped mirrors...

    UdoB reacted to leesteken's post in the thread Best RAID for ZFS in Small Cluster? with Like Like.
    I though the other thread explained that (stripes of) mirrors have better read performance and never worse redundancy. If you want more redundancy and more (read) performance then a 4-way mirror has quadruple the read performance and triple the...

    UdoB reacted to leesteken's post in the thread Best RAID for ZFS in Small Cluster? with Like Like.
    RAID5 (with BBU) is almost, but not quite, entirely unlike RAIDz1 (with drives without PLP). RAIDz1/2/3 is not good for VMs but can give you more usable storage (but padding can be terrible for space)...
