    Massive performance improvement in Linux 6.12

    Yes ! I forgot this ! Thank you to have spotted that. So @sherrellbc shall wait for the Ubuntu 25.04 that will use Linux kernel 6.14 by default it seems (source : https://www.omgubuntu.co.uk/2024/11/linux-kernel-6-12-has-landed-and-its-a-big-one)

    Creating volumes for a VM

    Like @UdoB said, it is OK. I do almost what you did for a NextCloud VM. @louie1961 what is not optimal for you could be optimal for someone else. For example for simplicity, robustness, integration. Personally I like to have Proxmox Virtual Environment dumb and complete backup, knowing that all...

    Slow write performance in Rocky/RHEL VMs

    Personally I test thing after thing. For example iperf3 -F test network bandwidth + file access + potentially VM OS cache , VM FS cache, host OS cache, RAID card cache, disk cache, ... For disks I use : https://wiki.liberasys.com/doku.php?id=diskwipetests:disks_wipe_and_tests&s[]=test For...

    Massive performance improvement in Linux 6.12

    6.12 kernel will come with Debian Trixie (see : https://packages.debian.org/testing/kernel/). Proxmox may integrate it before Trixie release. We just have to wait. Or you can try kernel compilation ;)

    reboot whole cluster because of CPU throttling, after new update

    I do not have enough elements to help you to take a decision and we are in a community forum. I take time for free here to help people. I won't assure anything and I think you can understand. I've only checked the recommendations (see...

    reboot whole cluster because of CPU throttling, after new update

    - so not following good practices - so not following good practices - ️ - I sell mostly basic subscription. You do not need a lot of tickets. Proxmox Virtual Environment is very stable. But you need good Linux admin skills.

    PVE crashing / hanging with very high load average

    @usridzero : And when you have the problem, you are not doing any backup and there is no special IO waits on the OS disk ? Although you might think that CPU bug is not related to your experience with changing kernel, it might be correlated. You never know how the kernel manage CPU timings or...

    reboot whole cluster because of CPU throttling, after new update

    Helllo Cairo. - so all networks goes thru only one physical link ? - so OS is on the same disk as LXCs - because swapping is slow and slows down the whole system (I put swapiness to 0 or 1 and monitor swap usage in big clusters) - look at details here, you have several levels of subscription...

    Installation with ZFS mirror on SSD super slow

    Big blocksize, not really... 2 and 4 disk blocks (see https://unix.stackexchange.com/questions/178899/optimizing-logical-sector-size-for-physical-sector-size-4096-hdd). Can you explain the condition of your two tests ?

    reboot whole cluster because of CPU throttling, after new update

    Hello, it seems to be a classical resource starvation case. In order to avoid this, you should follow the best practices : - admin network, data network (iSCSI, NFS, backups) and VMs network should be physically separated - OS disk should not be the same as VMs disks - you should not come to a...

    Installation with ZFS mirror on SSD super slow

    What are you fio parameters ? Did you check the different cache usages ? You can look at my procedure here, maybe this would help : https://wiki.liberasys.com/doku.php?id=diskwipetests:disks_wipe_and_tests

    Can you list the content of the NFS for example ? And in how many time is it done ? time ls /mnt/pve/SynologyNFS

    [SOLVED] Cannot extend volume group ( over iscsi ).

    @bbgeek17 : yes, normally you should use pvresize, then vgextend (and then lvextend bot Proxmox Virtual Environment will manage it from GUI))

    NFS 4.1 - How does proxmox gets the status?

    @dcsapak : it seems that first you check the /proc/mount entrie and then you check if it is mounted (see https://github.com/proxmox/pve-storage/blob/master/src/PVE/Storage/NFSPlugin.pm - from line 108 : sub status {. But I am wondering if sub check_connection (line 162) is used in the GUI...

    Would it be vgextend that you are looking at ? https://www.linuxtechi.com/extend-volume-group-size/

    PVE crashing / hanging with very high load average

    Hello usridzero, just an idea : if you have only one disk and the VM are eating IOs, it is quite normal that the OS will hang/freeze/crash. Did you try to monitor the ressources with "atop 1", or "systat -xk 1" ?

    Configure MAC prefix via webUI does not allow xx:xx:xx:Y format

    Hi there Petr ! To my point of view, it is OK. MAC address is randomly generated. Thus collision probability is : 1 / ((2^24) - number ov VMs) I think. The risk is acceptable for me. Maybe you have an installation with plenty of VMs and this is not acceptable. Thus I see at last 2...
