Monitoring proxmox and hardware?

February 20, 2025, 3:12 am

Hi all, how are you monitoring/alerting key metrics like:
- hardware issues
- disk utilisation
- ZFS issues (integrity etc.)
- SMART errors
- network issues

Primarily for the proxmox hosts but also the VMs?

I've used Zabbix and Nagios years ago - are they still "the cool kidz on the streetz"?

Probleme mit Hot Plug an HDD

Hallo,
ich habe mir als zusätzliche Sicherungsplatte eine Seagate Exos X-X16 geholt. Die Festplatte ist direkt an einem SATA am Motherboard angeschlossen. Dieser ist Hot Plug fähig und auch im Bios aktiviert. Da es sich hierbei um eine Zusätzliche Sicherungsplatte handelt läuft diese nur gelegentlich. Da auch die VM nicht permanent benötigt wird, sind beide die meiste Zeit aus. Wenn ich nun die Platte mit Strom versorge läuft diese hoch. Wird allerdings in Proxmox in der "Node" nicht...

NFS Share to Proxmox Host Permissions

Hi, I a have setup an NFS Share on my TrueNAS server and am trying to mount it in my proxmox host (node). I can't seem to get proxmox to mount the NFS as any user other than root.

My TrueNAS NFS share is configured with ACL permissions to allow specific user/group with assigned UID. I tried creating a new user in proxmox with the same UID as TrueNAS and specifying the mount with that user but still get denied due to permissions. The only way I can get my NFS share to mount is if I select...

Preconfigured installation packs?

Just musing out loud, but I'm sure there is a market for a set of OOTB Proxmox configurations. A "small office" set up with Nextcloud, email (Proxmox Email obviously ;-)), Samba, networking software, Zabbix etc. A "home server" one with Nextcloud, bookmarking, Zabbix etc.

(Yes, these are really all arguably better as LXC templates. Yes, choice paralysis is a real thing.)

My point is that I am sure a whole bunch of people install Proxmox but are then faced with "now what?". This seems like...

Hallo,
ich hatte bisher mein gesamtes Homelab unter ESXi in vielen einzelnen VMs am laufen.

Vor einiger Zeit bin ich im Rahmen einer Hardwareaktualisierung auf PVE umgestiegen und möchte jetzt dann mal mit dem Umzug anfangen.

Mir ist aber noch nicht so ganz klar, auf welches Pferd ich setzen soll... Ich möchte größtenteils auf Container setzen (LXC und/oder Docker) und nur noch ganz wenig in separaten VMs laufen lassen.

Was mir dabei wichtig ist, ist die Möglichkeit des Updates, das...

Disk cache settings for VMs on BTRFS

February 20, 2025, 3:41 am
$

I'm a little confused with the documentation. The BTRFS page says
Code: 
BTRFS will honor the O_DIRECT flag when opening files, meaning VMs should not use cache mode none, otherwise there will be checksum errors.
which I understand to mean set the disk cache to anything other than none.

However on the ZFS and Dir pages say that write back should be used instead of none if the storage does NOT support O_Direct.

What should I set my disk cache to for VMs on Proxmox 7? Thanks!

First time setting up proxmox-ve: 8.3.0 (running kernel: 6.8.12-4-pve).
I installed proxmox to an external SSD on a Lenovo Mq90.
After it said Installation successful! and rebooted I shutdown the system and installed the SSD in a Mac Pro 3,1.
It boots up Proxmox.
After some help from dj423, I was able to login to the web interface and everything seems to be working great - until it goes to sleep.
It goes to sleep after ~15min of inactivity. The web interface is unresposive, the monitor ges...

Proxmox ZFS mit zwei NVME SSD's + OMV als NAS

Hallo,

ich habe bisher eine USB SSD an meiner Fritzbox und nutze das als "NAS"-Ersatz.
-Folgendes passiert darauf:
-Backups aus IO-Broker
-Backups der Handyfotos
-Netzlaufwerk für Homeoffice

Ich habe seit ca. 6 Monaten einen Lenovo M710q mit Proxmox im Einsatz, auf dem einige Container (IO-Broker, Influx, etc.) laufen.

Da ich künftig meine NAS-Lösung durch was vernüftigeres ersetzen will wäre mein Gedanke folgendes gewesen:
-Den M710q durch einen M910x ersetzen
-2x NVME SSD 2TB

Transkodieren mit AMD-C/G-PU im Jellyfin-LXC?

Hi,
bisher war ich PLEX-Nutzer, da ich (historisch bedingt) einen PLEX-Pass besitze.
Jellyfin ist aber auch sehr schick.
Da dachte ich mir, baust 'nen LXC mit Storage für die Medien und lässt PLEX & Jellyfin drauf zugreifen.
Klappt soweit recht gut.
Ich habe im PVE-Host einen AMD Ryzen 5 3400G und keine eigene GPU.
Hat jemand ein ähnliches Setup und könnte mir einen Tipp geben, wie ich die AMD GPU durchreiche?

Backup to PBS very long due to missing dirty bitmap

Hi guys
I know there are many threads about, but I haven't found the right one who explains my question perhaps.
How is the behavior or where do I find the documentation of PVE for handling the "dirty blocks bitmap" for doing incremental backups?
We know:
  • If a VM has been stopped, the Bitmap is deleted
  • But there must be other cases…
Yesterday one of my VM suddenly had it lost and says:
scsi0: dirty-bitmap status: created new
Sometimes we also see "scsi0: dirty-bitmap status...

Guten Mittag zusammen,

ich habe mich viel mit den Einstellungen von VMs beschäftigt und auch verschiedene CPU Typen getestet.
Am besten soll ja immer Host sein, das kann ich bestätigen. Nun frage ich mich, wenn ich auf meinem Intel NUC mit N97 eine Ubuntu VM mit CPU Typ Host erstelle und sichere ob ich das Backup unter einem System mit AMD Ryzen Prozessor wiederherstellen und auch den CPU Typ Host verwenden kann?
Ist im Backup irgendwo gespeichert dass eine Intel CPU der Host type ist oder...

Ceph won't start anymore

After a power outage, the main Ceph of the cluster won't start anymore (pve1).

As far I can tell, the only service failing to start is ceph-mon@pve1.service

All the others seems normal.

Nodes:
pve1 (3 osd - 1tb each)
pbs (only acting as mgr)
pve4 (only acting as mgr)
pve2 (3 osd - 1tb each)

pve1 and pve2 are "raiding 5" each other, forgot the exact name. With these 1tb disks (3tb total) I created a 2tb volume (1tb for parity), and shared it to the whole cluster. That volume is now...

got into a bit of a mess.

i'm running proxmoxVE on Disk1.

i then installed proxmoxVE on Disk2.

now when i try to boot into Disk1, it boots from Disk2.

strange thing is, that dis2 isn't even listed as bootable device from bios, because i needed to mod the bios with nvme module. so disk1 is selected boot disk, but uefi or something else is switching to disk2 in boot process.

tried to restore grub and vfat partitions, by overwriting the first 2 partitions of disk1 from a backup before...

Proxmox Migration – cannot request an IP after moving storage on new miniPC

Hello everyone,

I have a homelab running Proxmox (v6.8.x) on a Dell miniPC. Recently, I got a new barebones miniPC (MinisForum) and attempted to migrate by simply moving the storage and connecting it to the LAN. However, it's not working as expected.

The issue: The new machine isn’t getting a DHCP IP.
To be clear, the old static IP that was given in the first time setup is fine. The problem is that it's not showing up in my router.
The machine simply won't...

Metric server: organization: value must be at least 3 characters long

Hi,

we already use the metrics server functionality from PVE. We wanted to adapt this to PBS, but have the problem that our organization name is rejected there because it is only two characters long. Is there a technical reason for the limitation in PBS? After all, the organization name is correct and is also accepted by PVE.

Best,
Stefan

Hallo zusammen,
ich spiele gerade etwas mit der API und dem thema remote migration. An sich klappt alles - also das kopieren einer VM bzw. eines Templates mittels API auf einen anderen Cluster.

Mein Problem ist nur, dass die VM nach der migration auf dem source node als "locked" gekennzeichnet ist - Kennt jemand das Phänomen?
Und wie kann ich das umgehen?

Ja, "qm unlock ..." hilft, aber bringt mir nichts, wenn ich hier mit einem API Key arbeite - "Only root cat set lock" ;)

Hi,

I've been using Proxmox for a while now and I just wanted to say that I really appreciate it that Proxmox Server Solutions provide the CE edition to us amateur enthusiasts free of charge. It's great to have that just for us guys with only a couple of machines at home who aren't serious corporate users but who still need a robust, reliable solution at home. Not only is it a nice gesture, but a great marketing tactic because I've sung your praises to many of my colleagues who are in IT...
