Hallo, we are currently evaluating a new Proxmox cluster with Ceph. Facts: 10 servers in a cluster 2 data centers 5 Server á Data center 12 hard disks á server The installation and configuration is already finished, currently only test VM's are running. Now I noticed during failure tests that...

Merci! Hat geklappt! Wir sind davon ausgegangen, dass die CPU's über die Cores und Sockets gesetzt werden und der VM übergeben werden, nicht von den VCPU's :) Danke!

Hi Marcel, also unser Problem ist, in den Optionen ist Hotplug für CPU und Memory eingeschalten. Wenn ich dann in den Hardware Optionen weitere CPU Cores hinzufüge, wird dies nicht übernommen. Die Änderung ist rot angezeigt. Die VM muss für die Änderung also neu gebootet werden. Memory...

Hallo zusammen, eine eigendlich simple Frage gestalltet sich recht schwierig. Undzwar möchten wir bei allen VM's die Möglichkeit haben, CPU und Memory hotplug zu nutzen. Hierzu gibt es ja schon folgenden Artikel: https://pve.proxmox.com/wiki/Hotplug_(qemu_disk,nic,cpu,memory) Muss für die...

That's the way how you should do it :)! Nice! (we are happy if you give us a like :) )

There is a latency limitation of ~3ms for corosync. (symptoms are flapping node availability in the pve gui) Is your network under 100% load?

Hi, no your right! To create a cluster you can use the GUI (this is the simplest way) or over your CLI. pvecm create CLUSTERNAME -ring0_addr FIRSTIP -ring1_addr SECONDIP The prefered ring will be the ring0_addr. After you create it you can join the other nodes by joining the cluster over...

hi, when i set the boot order in a vm to first boot from net , proxmox does only try to boot from the 1st network interface. how can i configure proxmox to also try every additional configured network interface ? Regards Frank

@t.lamprecht Are there any updates ? We have the same problem. All nodes have the same versions - we do not plan to update. proxmox-ve: 5.2-2 (running kernel: 4.15.18-7-pve) pve-manager: 5.2-9 (running version: 5.2-9/4b30e8f9) pve-kernel-4.15: 5.2-10 pve-kernel-4.15.18-7-pve: 4.15.18-27...

@Knuuut Because I just wanted to know following :D

https://forum.proxmox.com/threads/zfs-mit-hardware-raid.35671/ FYI - if anyone can speak german. (Google translator is an alternative for this problem :-D)

Please read this completely (also the comments) and forget the first enumeration from the second part of this article. https://mangolassi.it/topic/12047/zfs-is-perfectly-safe-on-hardware-raid This is exactly what I want to tell you. We use ZFS as (any other) filesystem. We just want to use the...

We are only using it as filesystem to have the replication features. In the event that the controller has a hardware defect, we will get a new one from the manufacture and rebuild the ZFS Pool.

Hi @ All, we tested the solution with our hardware RAID controller. This solution is perfect for us. We do not have any overhead (file size) and the performance is sufficient for our purposes. We know that the hardware RAID controller shouldn't be used but on all our systems we count on it...

@guletz Okay, we changed our config to test some other setup. Using a 2GB Raid Controller created 2 Disks using 12 HDDs for each virtual disk (raid 6). So we get out 2x 106TB virtual disks. Then we created a zfs striped pool using these 2 disks. zpool create -f -o ashift=12 HDD-Pool sda sdb...

raidz3 with 24 disks with sector 4k We plan adding about 100 TAR files once a day in future. We will not override or delete existing files. We don't want to use CT's cause of our company policy. Greetings

@ @guletz :) -ashift 12 -backups - Only Replication to the other node -Network: lwl 10GB direct cabeling between the two nodes -Files: many small TAR Files -pre-production test will be done soon
