    IO delay

    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.

    Having high swap usage on one of my Proxmox VE nodes

    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...

    [SOLVED] vzdump causing swap usage overtime

    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...

    Swap is Really High on One Node But Not Others

    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...

    Balloning & swappiness

    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...

    Swap almost full

    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 -...

    High SWAP usage on Backup

    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

    Proxmox and swap partition

    Is there a reason why the default install of Proxmox VE doesn't allocate it's own swap partition? If not, should I be providing my VMs with access to swap space and if so, should I be providing this swap space on SSDs or HDDs?

    Trying to understand LXC RAM and SWAP allocation

    I have a workstation with 256 GB RAM, and by default the host has only 8 GB SWAP. With the two LXCs I have, as they can potentially use a lot of RAM, I committed 192 GB RAM and 64 GB SWAP to both. My question is, in a situation where both LXC reaches a high usage and they consume more than 256...
