Like.
Cool :) I think this stuff is not well-known, because the Ceph tooling for the longest time only let you specify a failure domain and all the CRUSH rules were created with a single chooseleaf. And creating custom CRUSH rules isn't well... -
UdoB replied to the thread CEPH Erasure Coded Configuration: Review/Confirmation.I have tried to test it - and it works as you describe :-)

Your usable space calculation is correct, but not the placement. Ceph doesn't place k and m chunks separately, it's all just chunks to the CRUSH algorithm. For each PG it will choose three hosts, and then for each of those hosts it will choose...

UdoB replied to the thread CEPH Erasure Coded Configuration: Review/Confirmation.As stated I am not a Ceph specialist. I do not understand what you want to achieve with this construct. And because I am curious I write this reply ;-) In my understanding the usable space is up to 7/12 = 58.3 percent. Right? The "m=5" makes...

UdoB replied to the thread Backups in die Cloud.Sicher? Das Angebot war gelegentlich "ausverkauft" und wurde mehrfach erneut ermöglicht. Momentan enthält https://www.tuxis.nl/en/proxmox-backup-server/ den Satz "You can choose from a free account for home use or testing, ..."

UdoB replied to the thread Backups in die Cloud.Ja, die Stromkosten sind in .de echt... ärgerlich :-( Ich behelfe mir (im Homelab) durch Kaskadierung. Es läuft nur ein einziger PBS 24*7. Der ist schnell, hat "nur" SSDs (keinerlei HDD), nur begrenzte Kapazität und somit nur eine geringe...

UdoB replied to the thread Backups in die Cloud.Wenn man "nur" Space einkauft, muss man ja einen PBS selber aufbauen, lokal oder remote. Das treibt wiederum die Komplexität in die Höhe. Gerade im Desaster-Recovery-Fall, will ich aber, dass das Backup einfach verfügbar ist - ohne dass ich erst...

UdoB replied to the thread HA with storage replication?.Yes! While ZFS replication is not "shared" in the classic sense, it qualifies for this use case. Of course you lose the data from the last replication point-in-time to now. If that's acceptable depends heavily on your use case. In my homelab I...

UdoB replied to the thread Looking for Advice on New Setup.Whatever you do with this conglomerate: a CACHE does help only if you read the same data multiple times. And ZFS has its own optimized cache already in place: the Adaptive-Replacement-Cache "ARC" is always present - in RAM. (( The other often...

UdoB reacted to beisser's post in the thread 10Gb Netzwerk erreicht nur 1Gb Geschwindigkeit with Like.
ok, 2 platten im stripe sollten okish performance liefern (vermutlich irgendwo zwischen 200 und 300 MB/sek), sofern ausser deinem smb kopiervorgng sonst nichts drauf zugreift. gleichzeitig haben die disks aber keinerlei fehlertoleranz. ein...

Version 5.x ist viele, viele Jahre alt. Deprecated bedeutet das diese Version wohl bald aus Proxmox/KVM entfernt werden wird. Aus diesem Grund würde ich dir empfehlen die Version auf die aktuelle 10.x zu erhöhen. Die Netzwerkarten am besten...

Is the internal flash a sd (mmc) card? Then you won't be able to install ProxmoxVE with the regular iso image see https://forum.proxmox.com/threads/unable-to-get-device-for-partition-1-on-device-dev-mmcblk0.42348/ In theory you could first...

UdoB reacted to Johannes S's post in the thread Setting up remote access to the Gui - From outside the local network with Like.
And if you prefer not to route your data through the network of an external company: headscale offers a way to run your own tailscale-compatible server on a vserver. Alternatively you could use something like pangolin (which basically is a kind...

UdoB reacted to jackowheel's post in the thread Small web UI to start/stop VMs/LXCs via Proxmox API with Like.
Hello everyone, I wanted a lightweight UI accessible from anywhere to start/stop resources from my phone without exposing the Proxmox UI on the internet. I couldn’t find anything that already existed for this use case, so I built my own. In my...

UdoB reacted to Johannes S's post in the thread Ich habe versucht mein Proxmox-Setup abzusichern - Meinungen/Ideen? with Like.
Das macht einen Cluster-Kommunikation kaputt, für den Aufbau eines Clusters also root-Login wieder erlauben. Passwort-Login kann und sollte man aber natürlich deaktivieren. Für die Backups rate ich dringend auf pull-backups ( per vpn)...

UdoB reacted to Foxhunter_de's post in the thread Ich habe versucht mein Proxmox-Setup abzusichern - Meinungen/Ideen? with Like.
Hallo zusammen, ich erhoffe mir von dem Thema, auf Dinge aufmerksam gemacht zu werden, die ich vielleicht übersehen oder vergessen habe, und generelle Meinungen bzw. Empfehlungen. Auf meinem Server läuft VE 9.1.2. SSH Login nur mit extra User...

I use ZFS for example: vdev0: 3x HDD Drive ZFS RaidZ1, vdev1: 3x HDD Drive ZFS RaidZ1 and vdev2: nx SSDs as ZFS special deivce. So a full SSD Special Device is a must with HDDs. So i can read/ write with 2.5 GBit/s Network speed. Please read...

It was discussed in the past, did you already search the forums for it? https://forum.proxmox.com/search/8806046/?q=hardening&o=date Following threads I would consider quite helpful...

UdoB reacted to Kingneutron's post in the thread Making root volume live in the lvm thin pool ? with Like.
A) Proxmox is not really designed to work like that (rootfs in a thin pool) and B) you are likely to have issues when it's time to do a large dist-upgrade. C) Just because you can, does not mean you should. D) You are building a more fragile...
