I Summerized this Thread a little, to help to keep Track:
-- All issues are Starting with Kernel > 5.15
- On 5.15 there are no issues.
- On 6.5.X there are still all the same issues.
- Kernel 6.8 will Probably fix all Issues

Issue: WS2019 100%CPU / Freeze
Hardware: AMD...
@trey.b
Thanks for the detailed writedown.
I think the Proxmox Team or @Thomas Lamprecht will be able to Provide the 6.8 Kernel, or as Testing Kernel at fullowing Dates:
March 28, 2024 (UTC) : kernel feature freeze
April 1, 2024 (UTC) : beta freeze
April 11, 2024 (UTC) : kernel freeze...
Yes docker is an non issue inside lxc containers on zfs anymore.
After Kernel 6.2 and before Before zfs 2.2 docker worked inside lxc containers on everything except zfs.
However there is maybe 1/2 docker images, that might not work, but i didn't camed across against any.
99,9% of all docker...
Das ist definitiv eine Lösung aber keine gute.
Während bei LXC Containern das Resizing von Fenstern und ncurses (also alles mit cli gui) perfekt funktioniert, ist das bei VM's mit Serial Port und Xterm eine Katastrophe, so sehr das es fast sinnlos ist.
Egal ob bei debian/ubuntu VM's und auch...
Okay some Answers to my Own Questions:
1. Disabling ARC, is not a good idea at all, it should not be done and is not even really possible.
-> ZFS needs ARC, at minimum if you have Compression ON, on the pool. Since for the Compression the Blocks gets Copied to Ram anyway, if they aren't in Ram...
i Have in one Server an Raid z2 with 8x 20TB, without any issues, its fast enough for a Movie Collection xD
12 Drives is even Cooler, Z2 is really not an issue, but you can even do 4x Z1 in a stripe, which brings more performance.
Z1 on ZFS is not an issue, since there is no write hole (if the...
Yeah, its an x570 with an Ryzen 5800X, so no other GPU.
But i have no issues at all, tbh its my favorite GPU for Linux or Proxmox, or however you take it, since you don't need to do anthing, because everything is already in the Kernel.
The only wish i would have, would be SR-IOV, but there are...
About the 3rd point.
The issue with the ARC idea is, that with limited ARC, i will get a lot of Cache Misses.
Cache miss will introduce additional Latency, as it does anyway.
On Normal Servers, where the speed of disks/ssds are no where near to memory speed, ARC is definitively a win.
But if...
I bought 2 Server, that i want to use in a Cluster, those 2 Server are exactly identical, thats the Specs of one Server:
1x 9274F
12x 64GB DDR5 4800
8x 3,2TB Micron 7450 Max (VM Storage)
2x PM9A3 960GB M.2 110mm (Proxmox OS + ISO's)
2x 25G Interfaces (Intel E810)
So in the end it's a...
An 6.8 Kernel right now, is not as easy, or maybe even not possible right now.
ZFS isn't even ready for the 6.8 Kernel at the moment. The 6.8 Kernel is just realeased some days ago.
Don't expect that Lamprecht & Others put hours of work to fix Compilation, which can be extremely Risky even if...
Bad idea:
If your S2S Tunnel is down and you shutdown/start any VM on (The one Node), it wouldn't start because of Expected votes in the Quorum.
You cant even boot the one Proxmox node, that is behind the Tunnel. You will have to set always "pvecm expected 1" on that node to boot any VM while...
Hey @fabian i just camed across this issue either, after like 2 years of using proxmox on all my servers xD
Wouldn't it be better to simply not display the IO Graph? Or Exchange the Graph with something like "IO is not Available with CT's on ZFS"
Everything should be better as an empty graph...
Thank you a lot!
CONFIG_VIRTIO_BALLOON=y is indeed here "y" everywhere.
Yesterday i rebooted some VM's and tbh, it seems to be working till now, at least i cannot say for sure that it isn't working or give any qualified answer at the moment.
All the restarted VM's almost match what pve is...
Hi :)
The docs mention "All Linux distributions released after 2010 have the balloon kernel driver included. "
https://pve.proxmox.com/pve-docs/pve-admin-guide.html#qm_memory
Google says, its activated once "you install qemu-guest-agent"
But in my findings with almost all Linux Guests, for...
What is with the Retention Settings Tab in the Backup Section of PVE-Datacenter?
I mean i can define there for every VM a Separate Backup Task with separate Retention Settings.
Isn't it the same as the Prune Settings in PBS?
Cheers
Hey Dunuin :-)
As you see im very new to PBS, but glad to see you again after all the time :-)
Thanks for the Answers & for the Tip!
I Thought already of an local PBS+Sync either, but i have almost no Storage at that Crap Server.
In Short i don't have a clue of how Sync works, if its more like...
Hi, i have the following Examples:
Private Example:
- PVE Server Hosted at Hetzner
- Backupserver at Home
Commercial Example:
- A lot of PVE-Servers + PBS at the Companys main Location.
- Company External sub Location has an PVE-Server
In both situations we want to Backup VM's, but the WAN...
