Ich habe noch keinen Gegenbeweis gesehen, auch wenn SCALE nun auf...

UdoB reacted to Falk R.'s post in the thread Tastatur Layout zur Installation, bzw. root PW, Hostname und Mail ändern with
Like.
Ja klar. Das liegt nicht am Proxmox Installer. Wie installierst du denn? Per Bildschirm direkt angeschlossen oder per Remoteverbindung mit einem BMC? Eventuell mal ein Kennwort versucht, welches auf deutscher und englischer Tastatur gleich ist... -
Yes because swapfiles on ZFS datasets or ZFS volumes are problematic see https://pve.proxmox.com/wiki/ZFS_on_Linux#zfs_swap If somebody wants to have swap with ZFS he should use a dedicated partition or using zramswap (since then the swap won't...

You might want to read the best practice pages for Windows guests, it's important to have correct drivers and machine settings for sufficient performance: https://pve.proxmox.com/wiki/Windows_11_guest_best_practices...

UdoB reacted to wigor's post in the thread Prune Job: Keep first backup of the day instead of last? with Like.
Hey kleumo, maybe on idea is to use namespaces, one for the snapshot mode backups and one for the stop mode backups and configure different prune options?

UdoB reacted to bbgeek17's post in the thread How can an existing .qcow2 image be attached to a VM without modifying it ? with Like.
You can place the QCOW in appropriate directory ( /var/lib/vz/images/vm-101 https://pve.proxmox.com/wiki/Storage:_Directory). Name it appropriately, ie vm-101-disk-10.qcow2. Then you can " qm disk rescan --vmid 101". This should pick the disk up...

UdoB reacted to IcePlanet's post in the thread Newbie question on RAM overprovisioning (8VMs - 64 GB RAM) with Like.
The good news is that now on test installation everything runs on 1st attempt without any complicated settings. On the bad side the windows installation (moved from physical machine) is extremely slow and has very slow response (lagging). It is...

UdoB reacted to alexskysilk's post in the thread Ceph: Verhalten beim Ausfall eines Knoten with Like.
Its worth revisiting what ceph is and how it works. ceph is software defined storage, which is to say there is an algorithm and rules. In a normal virtualization workload the pool rules look like this: replicated size 3 shards (members) in a pg...

UdoB replied to the thread Newbie needs recommendation for new install.....Well..., I disagree. One major feature is to self-heal damaged blocks (detected during "scrubbing"). That feature requires some redundancy to work - so it does NOT work with a single device. (There is an option to store each and every block...

UdoB reacted to Johannes S's post in the thread [SOLVED] TrueNAS Scale NFS Datastore very slow with Like.
Well TrueNAS also allows to run VMs or LXCs with it's newest release so I would expect way better performance if you setup PBS inside a TrueNAS VM or a LXC. For LXC there is a writeup in this forum...

Ok, Mistake was not on PMG-Side. It was a broken NAT rule on our firewall.

UdoB replied to the thread Ceph: Verhalten beim Ausfall eines Knoten.Dann geschehen (früher oder später) böse Dinge. Der Ceph-Pool ist jedenfalls sofort degraded - und bleibt es auch dauerhaft. Es ist ja kein Reserve-Node vorhanden, der die Daten (size=3) aufnehmen könnte --> keine automatische...

UdoB replied to the thread How to install AmneziaWG (Wireguard with obfuscation)?.Put it into a vanilla Debian VM! Never do such things on the node itself. You are leaving well tested and "known good" territory immediately...

UdoB replied to the thread Costant CPU usage.ZFS works with a few GB. I doubt BTRFS works fine without any Ram... The historic rule (1GB Ram per 1TB disk and/or "50% of Ram") was dropped a long time ago. The current default maximum ARC for PVE is "...clamped to a maximum of 16 GiB.", from...

UdoB replied to the thread Hardware question: Hardware Raid for OS (Proxmox ve)?.Hardware Raid is the "classic" approach. Nowadays that one lacks some sophisticated features: https://forum.proxmox.com/threads/fabu-this-is-just-a-small-setup-with-limited-resources-and-only-a-few-disks-should-i-use-zfs-at-all.160037/ PS...

UdoB replied to the thread Newbie question on RAM overprovisioning (8VMs - 64 GB RAM).Followup question: Does your setup really need eight machines? Or do you have eight users with one VM each? If the latter is true: can't they use the same VM? In that case you could give it 32 GiB to let two users run that 16 GB job at the same...

UdoB reacted to leesteken's post in the thread Newbie question on RAM overprovisioning (8VMs - 64 GB RAM) with Like.
I fear ballooning works even worse and simply takes away memory (withough negotiating with the OS inside the VM) from all VMs (if they have the same number of shares) and in this case will only result in all VMs having the same amount (which is...
