    [SOLVED] Performance comparison between ZFS and LVM

    So as I undestand ashift, volblocksize and recordsize should all match the page size / sector size of the underlying blockdevice. So my disks are reporting a 512 page size, yet techpowerup reports that it's 16KB, and Kingston does not provide this information in the datasheet nor anywhere else I...

    [SOLVED] Performance comparison between ZFS and LVM

    Hello everyone, we've finally decided to test internally a 2 node cluster pve installation with zfs and replication, and vm performance is considerably slower than what we've got used to with hardware raid and lvm, Our test installation is meant to replace an old single node installation...

    Raid Controller Configuration

    Hello everyone I was wondering what is the proper way to setup the hardware controller. We usually setup Proxmox on Dell servers with the PERC H755 Hardware Raid controller which can be configured with different read/write policies, Usually we configure our storage on raid 5 or raid 10 virtual...

    Active-Backup interface keeps switching between the two links

    Update: after a bit of research I think that the error in the dmesg logs has little if anything to do with the issue I described. Thats related to a bug (?) of the i40e driver, as I understand it: at first the interface tries to filter the vlan tag of the packets instead of just passing it on to...

    Hello everyone, Currently I've got my networking setup like this: The machine running PVE has two NICs: one is the default embedded NIC that came with the motherboard, a Broadcom NetXtreme Gigabit Ethernet (BCM5720), which is a RJ-45 dual-port, 1 Gigabit Ethernet Controller, the other is an...

    Hello I'm posting a bit late, but I was having the same issue, the machine worked fine, but the system dropped the noVNC console connection during the init process, right when mounting /. So the DSM Virt Manager noVNC console kept getting stuck at the stage posted in the screenshot above. At...

    Intel(R) 10G 2P X520 Adapter not detected

    Hello, welcome to the forums! I dont think there is any issue with proxmox, in my case the issue was that the cards had an unsupported sfp+ module. I've used the card on two different pve installations now, in the first case the issue was that we simply plugged the card in the pcie slot of an...

    Intel(R) 10G 2P X520 Adapter not detected

    Hello everyone! I can confirm that this was also the issue for us... The colleague that installed the card didn't put it in the right slot :rolleyes: So the issue was on our side and not with the proxmox or the card, Sorry but I'm taking over for the colleague that started the thread, do I...

    Intel(R) 10G 2P X520 Adapter not detected

    Unfortunately no, we tried to install intel updated ixgbe (5.18), but it is still not detected. Look like that card is just incompatible. We will update the thread if we found a solution.

    Intel(R) 10G 2P X520 Adapter not detected

    Goodmorning, we are installing Promxox with ZFS on an old server to use it as replica on the main one. To be precise the server is a Dell R730 with an Intel(R) 10G 2P X520 Adapter installed and detected on the IDRAC, but not on Proxmox. Reading on the internet, look like this card is managed...

We applied...

    VM Hang during high data transfer

    We just discovered this that could be helpful, while the vm was hanging, ALL the Linux vms inside the same node logged this in the dmesg: [ 2055.223604] INFO: task btrfs-transacti:399 blocked for more than 120 seconds. [ 2055.224006] Not tainted 6.1.0-9-amd64 #1 Debian 6.1.27-1 [...

    VM Hang during high data transfer

    Hi, we have a Proxmox server built with ZFS that hosts various vms, including one that is a Debian Bookworm with a Samba domain controller. We experienced a weird problem where if we transfer data greater than 5GB, the vm could completely hang and become unresponsive, even from the built-in...

    [SOLVED] ZFS disk problems

    We did a lot of cold boot for testing and the problem didn't appear anymore, so i think it's pretty safe to say we solved the problem. Thanks for the support! Have a nice day.
