    UdoB reacted to yunmkfed's post in the thread Proxmox hangs after upgrade to v9 with Like Like.
    I opened this a few months ago and I am sharing the conclusion here: It turned out it was a defective CPU that Intel is still replacing under warranty. The video shows exactly what arrives when Intel ships a warranty replacement for a faulty...

    UdoB reacted to leesteken's post in the thread Improving performance of RaidZ1 with Like Like.
    Is this 6 drives (stripe of mirrors)? What could give you twice the write (and the performance increase of PLP on top of that) and up to 4 times the read performance. Or just one 3-way mirror? Which give you better write IOPS only because of the...

    UdoB replied to the thread Easy Way to Automatically Forward Ports to VM's / LXC Containers.
    Yes, that's a "classic" approach. You will end up with a) open ports and b) the problem of a dynamically changing external IP address and c) some glue in form of those forwarding rules. If you have an external VPS or are willing to rent one for...

    UdoB replied to the thread PBS backup space grow up constantly.
    In your first screenshot there is "Prunes 0". Is this still the case? You may trigger pruning manually via "Run now" - and watch the log live. Are namespaces involved? The "Edit: Prune Job" has a "Max. Depth" setting. If this is set to low it...

    UdoB reacted to bbgeek17's post in the thread Noob with weird network issue with Like Like.
    To be on the same page, none of this is PVE specific. You are dealing with basic Linux network management. At one point in the thread you mentioned that there is a "direct" connectivity between the clients, is there an actual direct cable? Your...

    UdoB replied to the thread Proxmox 8 to 9 introduced LXC terminal problems.
    When logged in, try reset. (If this sounds risky: read man reset.) I have no idea what triggered that behavior, but "reset" should re-initialize the terminal with sane values. Disclaimer: I do not use containers...

    UdoB reacted to daanw's post in the thread PBS backup space grow up constantly with Like Like.
    Looking at the screenshot, Prunes is 0 for both datastores. Are you sure you have set this up correctly?

    UdoB reacted to daanw's post in the thread Improving performance of RaidZ1 with Like Like.
    What you want for an OS/VM pool is random Read/Write IOPS. Striping your drives will always be faster than mirrors/RAIDZ (speed vs. reliability/parity..) but having drives with good random IOPS makes a much bigger difference. Practically this...

    UdoB reacted to leesteken's post in the thread Improving performance of RaidZ1 with Like Like.
    raidZ1 is known to not be good for IOPS: https://forum.proxmox.com/threads/fabu-can-i-use-zfs-raidz-for-my-vms.159923/ . And your drives might be consumer drives without =1&c[nodes][0]=16&o=date']PLP. Lots of threads about disappointing (write)...

    UdoB reacted to spirit's post in the thread [TUTORIAL] Proxmox VE unattended installation over debian with secureboot + crypto lvm for CIS compliance with Like Like.
    Hi, I have wrote a script to generate an iso install with debian + proxmox package merged + debian preseed file for automatic installation, with crypto lvm + specific partitions for CIS compliance. It's using secureboot with proxmox shim &&...

    UdoB reacted to jdancer's post in the thread ZFS with PERC H745: is RAID0 the same as JBOD? with Like Like.
    On 13th- & 14th-gen Dells PERCs, have to delete the virtual disks before switching it to HBA-mode. Call it a quirk. I've also had issues with the megaraid_sas driver in the past, so I just swap out the PERCs for Dell HBA330s, which is a true...

    Triple check if there is an IP address conflict. Your systems have static addresses, right? I've seen conflicts too often...

    Purpose Inspired by Level1Techs, I decided to replace my old router with a single box solution that's flexible, upgradable, and efficient. That includes using Proxmox to utilize spare resources without interfering with the vital router...

    UdoB reacted to RolandK's post in the thread Proxmox im RZ - pfSense VM oder Linux NAT with Like Like.
    also statt pfsense würde ich eher opnsense empfehlen, weil das kostenlose pfsense kaum noch gepflegt wird. aus sicherheitssicht dürfte sich da nicht so viel tun, aber grundsätzlich ist so eine dedizierte security appliance da schon der bessere weg

    UdoB reacted to awado's post in the thread [SOLVED] Kein TOTP-Login mehr möglich nach Zeitfehler with Like Like.
    Ok, dank KI & OpenCode konnte ich die Ursache jetzt doch selbst finden (lassen): In "/etc/pve/priv/tfa.cfg" wurde der Zugang gesperrt mit …"totp-locked":true… . Wenn man dort das auf "false" setzt, geht es wieder. Ich lass den Post mal so stehen...
