swap

For one of our VMs we allocated around 30 GB RAM. Every time we check the usage of resources, using htop, we see that the SWAP memory is always at 100%. Here is a picture: We are not sure this is normal behavior Even our swap memory in the proxmox GUI, the one for the entire...

Hallo, der Proxmox Support hat mir geraten meinen SWAP zu deaktivieren, da dieser auf zwei von vier Nodes auf 100% war. Arbeitsspeicher war jeweils auf etwa 60%. Ich habe auch bemerkt, dass SWAP vor allem da voll wird wo viele LXC Container laufen. Nun aber zu der eigentlichen Frage: Wie...

Guten Tag, ich habe einen laufenden Proxmox (Version 5.4) auf dem auch um die 10-15 VMs laufen. Gesamtfestplattenspeicher des Proxmox bewegt sich um die 1.2TB. Davon /data mit 1TB / ca. 100GB ROOT bzw. LOCAL / 8GB SWAP. Nun würde ich den SWAP Speicher gerne noch vergrößern, auf wenigstens...

Hi, I monitored my proxmox host with iostat found alot of "zd" devices writing once 8386556kb and then nothing changes. Most of my VMs got a vdev with thin provisioning and dicard of 8GB size for swapping (but rarely used because of swappiness of 1). Every time I reboot a VM it adds 8386556kb...

Hello all, I have Lenovo P500 Workstation with PCie NVME, 96GB RAM and 24core Xeon. Now after certain update, and I cannot recall which, PVE is acting strange like it has its own mind. I receive certain containers shutdown, I notice something is not working and I go look and it is shutdown. No...

Hey, I've been using Proxmox for a while now, and I'm very happy with it. The only major issue I could not solve so far with the manual is the swap usage. I'm using an NFS share for storage, and the KVM processes seem to use quite a bunch of swap, even trough there is plenty of RAM to use...

i have some proxmox servers installed, but on some of them there are swap enabled and always full. (i think it might reduce overall performance) there are lots of ram available. is it safe to disable the swap in proxmox host? ( it have around 20 containers and 4 vms running)

Habe PVE 6.2-6 mit 2 LXCs. Wie aus dem Screenshot zu sehen ist, ist beim ersten LXC die RAM Auslastung bei 3.19%, der Swap bei 47.1%. Hier läuft nur ein proFTPd mit mariaDB. Ist das normal oder kann/soll man da was optimieren? Der 2te LXC hat das RAM fast gefüllt, wobei ich auch hier nicht...

Hello, according to cgroupv1 docs: https://www.kernel.org/doc/Documentation/cgroup-v1/memory.txt It IS possible to set different swappiness value for each cgroup. How can i do this with proxmox CTs? Also: Can you please add GUI for this? This would greatly help me with swap issues caused by...

Hi, I have a bit of a problem with a test system I am running. Version details are below but the key factors are that I am booting from a single conventional hard disk, setup as a ZFS pool (called rpool). My reason for using zfs is that I plan to replicate the partition so I have a complete...

Hello. How do you configure swap on porxmox host machine ? I read different recommendations from: turn off swap at all to keep asa it is. I have 64 Gb RAM and 16 is used by containers and 1Gb swap in the same time. Is it good or not ? What do you advice to do or not with swap ?

Hi, I have a container which has very slow performance, and trying to debug this i realised that it's swapping so much even if it has a lot of RAM memory available: These are the status graphs of the hypervisor: As you can see the host does not seems to be overloaded. Another...

Hello! We are currently using a proxmox-server to virtualize about 20 windows machines (usually 6-8 hosts running concurrently). Currently, we are experiencing an issue with RAM-Allocation. We have 39.62% (24.91 GiB of 62.88 GiB) RAM usage and the SWAP usage is at 98.26% (12.16 GiB of 12.37...

Currently I am using proxmox 5.3-8 , I have followed all the method but I am unable to increase proxmox swap size which is currently 1 GB free -h total used free shared buff/cache available Mem: 31G 6.8G 286M 15G 24G...

Hi! I have noticed that one of my containers uses much more SWAP memory than allocated. Allocated are 512MB and it uses well over 700MB, although there is still plenty of RAM free. Can anyone give me a hint why? free -m says: Any ideas?

I set SWAP = 0 on every container I've on Proxmox, but they still use swap for some processes. I can check that from 'top' command. What's wrong?

Hi, I use Proxmox version '5.1-38'. I've 30 containers and VM-s. I want to change swappiness variable from 60 to 15 on several containers and it says 'sysctl: setting key "vm.swappiness": Read-only file system'. I think I should to change this on node but I don't want. Can I change it on only...

Hello, i am monitoring my Swap usage with Nagios and i get: SWAP WARNING - 35% free (4151 MB out of 12006 MB) I started with 4GB of swap. My Node has 48GB RAM in Total. Should i create even more swap space? I have a bad feeling if the node uses so much swap: What happens when the node...

Ever trying to gain just another percent of performance out of an admittedly sub-par setup, I have arrived at the sync parameter of zfs. Digging through some boards told me that disabling sync should be kinda-sorta ok if I trust my power supply, the data on the servers is well backed up and a...

When i click on datacenter -> search i see list of all containers in network. Also i can see memory and CPU usage of individual containers. I would like to see the swap size and usage in there, but there's no such option in columns menu. Can you please add it? Also i guess it might be useful to...
