swap

Hi, I'm running a hyperconverged cluster (Proxmox & Ceph) across three nodes. I've noticed the swap usage is creeping up. Each node has 192GB of RAM and 8GB of swap. Ever since system install I've reduced the swappiness to 10. Looking at what is actually eating the swap, it's a few KVM...

Hi there, I'm quite new with proxmox pve. I'm using small personal server for home purposes with two running VMs. Occasionally pve freezes and GUI is unresponsive. Currently it looks like this: CLI via SSH is accessible and running VMs too, but sometimes are VMs frozen. The following...

Hallo community, ich bin neu in Proxmox-Welt ;-) Ich habe ein Frage zu Drives für VMs Store. Festplatte ist angehängt (Physische Raid). Mir geht es nur um Partitionieren und Formatieren. Welche FS ist die beste Wahl für VM Store? ext3,ext4 oder btrfs? Hat es Sinn ein swap Partition...

Hello everyone, I'm facing an issue with understanding SWAP usage on my system and could really use some help from the community to clarify things. My Proxmox server consistently shows very high SWAP usage, nearly 100%, after running for several days. As far as I understand, SWAP is supposed...

My proxmox node show unknown status, but VMs can still be accessed. I try rebooting the node, but then it cannot boot and the VMs cannot be accessed. I show error here. Please help me, thank you guys!!

Dear All, Could you please provide a better solution for increasing the swap space from 8GB to 32GB. Please find the attached screenshot of my current memory utilization. Do I need to increase the swap space?

I upgraded my hosts and removed all SWAP's from the LXC clients and this is the result. Now I wonder if the problem was the code or the SWAP. I'm betting LXC don't like ZFS with SWAP.

I followed these instructions to get swap working in my setup. https://forum.proxmox.com/threads/how-to-run-pve-7-on-a-raspberry-pi.95658/ As I already had a running setup, I picked up from here: apt purge dphys-swapfile -y Everything went fine, but after the reboot, I ran this command...

I have three Proxmox VE nodes in my environment. Two of them have 4 cores/4 threads, one of them has 4 cores/8 threads. Node 3, the high swap usage one, has the 4 core / 8 thread and 32GB of DDR4 memory and as seen in the picture, it isn't even using 3/4 of the RAM available. The history of the...

Hello, I'm currently facing a strange behavior while Proxmox executes backup(vzdump.) When Proxmox starts backup, it also uses swap space, even if there is free RAM, anyone has any idea why? swappiness already changed to 10. proxmox-ve: 7.1-1 (running kernel: 5.13.19-6-pve) pve-manager...

This has been an issue for a while but it's recently become so bad that the entire host is responding slow when rebooting an LXC or VM, and it takes a little longer to load the consoles and different metrics pages (the VM metrics dashboard? (idk what it's technically called)). I wasn't really...

Hello, I'm posting here something I noticed on Proxmox 8.0.4 about Swap and Swapiness on Debian 12. Here is the configuration of my Proxmox VE node : 4 x Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz (1 Socket) (4 cores) 16 GB of RAM 6TB available (Raid 10 on 6*2TB Hard Disk) BTRFS Storage to...

Hello :) I encountered a strange issue today. One of my VM servers had some additions/changes done to it about two weeks ago. Without reduntantly explaining too much, a site with a map was added to a service its running. This new site with the map had been running fine for two weeks, but today...

Hi, tl;dr: How does swap and swappiness affect ballooning growth? I have a few VMs running Alpine Linux 3.15/3.16/3.17 and have over-provisioned the ram with the Ballooning device ticked. Most of them have the minimum ram set to between 512 and 4096 MB, with the maximum up to 75% of the...

Hello, The available swap space on one of the servers is almost all in use (7GB used out of 8GB), even though it has plenty of memory available (50GB used out of 188GB). I would like help with two questions: 1 - How can I reduce the use of swap, even having several containers using swap? 2 -...

Hello, one of my nodes has high swap usage when I run backups at night. The backup starts at 10pm and takes around 7 minutes for 5 LXCs and 4 VMs. Physical memory even drops around that time. Other nodes behave fine while doing backups. Any idea on why that is happening? Best regards

Hi, I have 3 HA servers each with 64GB RAM, one of the nodes, runs a KVM that keeps crashing every week, it is quite random how it occurs. Each server have 1GB Swap only that is full most of all the times. Now upon reading some articles and here in forum I disabled temporary the swap. Made...

Hi, i am a new proxmox user. With an installation on a RAID1 configuration i haven't SWAP created. Have i forget something or must i create SWAP on an other disk?

Hi all I have a 3 node-cluster for my development environment, all three nodes are basically same hardware. Cluster is pve6 and all lxc containers are centos7. In one of the nodes, all the containers have 0 swap memory, no matter what the configured amount is for any lxc. The main node las 16GB...

Hello for everyone, I have an standalone node with 380 GB RAM and CPU usage is normal, 20 CT and 15 VM with Promox 6.3.6, I don't have IO delay. I just now I'm trying to configure a new CT, but I found that the container doesn't have SWAP memory (I did that setup with 2 Gb) so when I start to...
