It seems that the problem has been solved. It is unbelievable, but the problem was the UTP cable between the Proxmox server and the router. The original 1.5m patch cable was used between the server and the router. I crimped the RJ45 connectors on... -

UdoB reacted to Johannes S's post in the thread [TUTORIAL] FabU: can I use Ceph in a _very_ small cluster? with
Like.
Well especially in a "I don't want to take the whole house offline scenario" for a house I think a two-node cluster with ZFS Storage replication is the better approach: If you have a low-power device (like a raspberry pi or a nas) which can act... -
Thats expected, the more backups you add the slower GC & verify will get due to how PBS handles deduplication (many small chunk files) and hdd's can't handle that well. Solutions would be, switch to all flash storage for your backups or if...

UdoB reacted to Partake5177's post in the thread VM with win server 2025 showing always high load on disk? with Like.
Solved: I did not create my hard disks on the zfs pool, instead it was running on local-lvm... That is why everything was so slow.

It would also make host backups a lot easier because then you would just have to backup the modifiable files (configuration etc). So I see the benefits, but I also see a huge issue: A big benefit of ProxmoxVE is it's flexiblity since it's...

UdoB replied to the thread Different storage amount shown in GUI and df -h.The 152 G is the virtual disk size, given to the virtual guest. The 58 GB is the space of one (or more, you didn't show us the output of df) filesystem(s). Often both are coupled and give similar size - but that is not a must. Examine the...

Extension for Multi-Backup-SW solution on a HA PBS Many admins learn to like the PBS solution from Proxmox although some practical features still are missing in contrast to Veeam like single file restore to the source filesystem location...

UdoB reacted to Skynetter's post in the thread Trycoo/WO-4 miniPC - 2.5GbE NIC, multiple NICs and multiple VLANs with Like.
After a lot of head scratching, I figured out how to get two NICs working on mini-PC. One is a 2.5GbE port, which needs driver update to run at 2.5GbE, and the other is a 1GbE port. The two NICs are on two different VLANs as well. Here's the...

Servus, es ist die letzen Tage von einem User noch sein "traum" Proxmox VE Server zusammen gestellt worden. Ich teile deshalb hier seine Auswahl, die Teilweise aus meinem erstern Vorschlag und Anpassungen an seine Bedürfnisse besteht. Viel Spaß...

In my humble opinion, what you’re seeing is just normal Linux behavior: it may swap idle pages even with free RAM to keep ARC/cache. Personally I’d suggest trying zram (with zram-tools or systemd-zram-generator) instead of disabling swap — it...

For reference: https://linuxatemyram.com https://chrisdown.name/2018/01/02/in-defence-of-swap.html I second the recommendation for zramswap

UdoB reacted to eroji's post in the thread PVE 8 to 9 upgrade issues, need help with recovery with Like.
Ok I was able to figure out the issue. The thunderbolt interface.d configuration was the culprit. The old config did not seem to want to work with 9. Checking the page I got the instructions from...
