Like.
Hi guys, Thanks so much for your inputs! Dont hold back :) It was our intention to run with the built in solution with proxmox. Not adding more outside feature. The idea being KIS. Keep it simple. We dont want the complexcity of storage... -
UdoB reacted to stamox's post in the thread Considering building a proxmox 3 node cluster with ZFS replication with Like.
@UdoB : I agree with you. I just noted the important points. He has a choice to decide how he should act.When you want to use free software, with the idea of it being semi-professional or professional, it is normal to take risks, especially if...

You cannot do mounts inside a container, since they share the kernel and are unprivileged (which is a good thing!). Do it from the Proxmox host (using a different mount point) and use a mountpoint for the container. Lots of threads about this but...

UdoB reacted to news's post in the thread Budget PC Build for Proxmox + CVI42 VM (with GPU Passthrough) with Like.
Hello @veryotaku i calculate a good proxmox server intel LGA 1700, with the parts of my local dealer in germany. You can see the base configuration. Mainbord, Biostar B760MXC PRO, DDR5 CPU, Intel Core i5-13600K, TDP max. 181 Watt CPU Cooler, be...

UdoB replied to the thread Budget PC Build for Proxmox + CVI42 VM (with GPU Passthrough).If that is your only goal then skip virtualization and install bare metal! If you want to run several VMs then sum up the RAM requirements and add 4 to 8 GiB for the OS and cache. Then double that resulting number ;-) Given that that software...

UdoB replied to the thread Considering building a proxmox 3 node cluster with ZFS replication.If the respective admin knows these tools (and their possible pitfalls) they will work fine. Both tools are well established and tested. But for a new user of the PVE eco system (with regard to replication) I do highly recommend to stay away...

UdoB reacted to stamox's post in the thread Considering building a proxmox 3 node cluster with ZFS replication with Like.
Hi, my five cents. ZFS isn’t a cluster filesystem → it’s single-host by design. It can’t natively do “live shared storage” across multiple nodes (like Ceph or GlusterFS). For replication/failover setups like you describe (A → B → C every 1–2...

UdoB replied to the thread problems with apt update with paid subscription on version 9.0.10.First remove the double entries, mentioned by @janus57 , then: On my PVE's there is only "Ceph Squid" offered in the "Repositories --> Add:Repository" drop-down menu. Maybe you should upgrade from Quincy to Squid - but do so following a guide...

UdoB reacted to Onslow's post in the thread [SOLVED] Network goes down after starting up a virtual machine with Like.
You wrote: Which, precisely, IP address does the VM get? The symptom is similar to an IP address conflict. Maybe the DHCP server gives the same IP address that PVE host is using? What is the DHCP range?

UdoB reacted to Johannes S's post in the thread Security: recommendations for going prod with pve with Like.
One thing not mentioned yet: Depending on compilance regulations and your Paranoia Level you might want to disable kernel-samespace-merging to prevent some attacks: https://pve.proxmox.com/wiki/Kernel_Samepage_Merging_(KSM)

There is now zfs rewrite,which you can use for rebalance
-
UdoB replied to the thread Possible to expand zfs raidz2 Array.Six of them in an additional/second vdev? Yes. This has the advantage of doubling the IOPS of the pool. The disadvantage is that there is no automatic re-balancing (yet). Yes. That's the "classic" approach. It has the advantage to not require...

UdoB reacted to orwadira's post in the thread [TUTORIAL] Use Mobile shell (Mosh) with Proxmox with Like.
Dear all. I have done a quick search on these forums and found an old thread, but decided to start a new one with the TUTORIAL prefix, as this is an area where I feel there is not much up-to-date information online. It is about "Mosh", or the...

UdoB reacted to Kosh's post in the thread Problems after upgrading the cluster from 8 to 9 with Like.
Thanks, everything was resolved by updating to pve-manager/9.0.10 my nerves are saved :)

Hallo @bertige_berti, @Falk R. hat dir bereits die entscheidenden Hinweise gegeben. Das Problem ist, dass du versuchst, ein Verzeichnis, das bereits vzdump-Backups (.tar.zst-Dateien) enthält, als PBS-Datastore zu verwenden. Ein PBS-Datastore...

In the case of power loss there is no way to live migrate the VM's RAM to a new host. In the case of fence that host has lost communication to the cluster so there is no way to migrate the VM's RAM to a new host. The question left is if one...

UdoB replied to the thread HA starts VM after proper shutdown.There is no state it can inherited. It can only start; it can only boot to then be running again. If a host is dead the VM is too ;-)

UdoB replied to the thread HA starts VM after proper shutdown.That question makes no sense. When a host is powered off a live migration is simply not possible. Live migration requires the source VM to be running! ;-)
