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...

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...

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...

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...

Hi, we are building a Proxmox machine for a client using ZFS and while in out lab we are experiencing a weird problem. The machine is a Dell PowerEdge R550 and it is configured as following: 1) a RAIDZ1 of 5 SAS-HDD disks 2) a RAIDZ1 of 4 SAS-SSD disks Often on boot, one or more of the disks...

Hello everyone, Would a pve that's hosting machines on more than one vlan need to have a different default gateway configured on each vmbr subinterface? the network is set up like this: all network devices: firewall, switches, access points, etc.. go on the management network: 10.100.99.0/24...

Goodmorning, we would like to ask some questions about PVE upgrades: - Is it possible to "dist-upgrade" the PVE safely while VMs are running? - If a new kernel is installed in the process, do we need to reboot or could keep using safely the old one until the reboot enable the new one? This...

Hi, for a client we will have to prepare a Proxmox server containing some Windows Server 2022 VMs and we found various threads reporting random crashing. We usually use few Windows machines, but the client requested some and we would like understand if there are some known problems. We don't...

Hi, we are evaluating ZFS for our Proxmox VE future installations over the currently used LVM. ZFS looks very promising with a lot of features, but we have doubts about the performance; our servers contains vm with various databases and we need to have good performances to provide a fluid...

Hi, we would like to create a two nodes system with Proxmox VE: the main one running all the virtual machines and the second one will receive a replica of each vm from the main one. We will not use HA, but we will manually "move" the virtual machines from the first to the second node in case of...

Hello, since a few days we're experiencing frequent lockups on ALL Windows Server 2016 VMs (i got 3). These vms have been running without any issue for months, but now all are experiencing the same issue. As you can see from the attached screenshot CPU spikes at 100% and there's no way to...

Hello, I have the following scenario: a backup task of 5 vms is running at 09:00 pm and, for simplicity, let's assume that each backup is 10 Gb. The backup storage is set to maintain 5 copies, and at the current time there are already 5 copies, so at the next backup the oldest should be deleted...

Hello everybody, At the beginning of this week, I just deployed a new PVE 4.4-13 cluster over a DELL VRTX with 3 blades with HA active for almost every VMs, and everything was working flawlessly. Storage is LVM, of course. Just one hour ago, for some unknown reason, one (or more? I didn't get...

Hello, could you share your working and tested configuration (DELL anyone?) for use with Ceph? I need a 3-nodes general purpose configuration which offers good performance (~10-20 vms). Details are welcome (hdd/ssd models, benchmarks, problems encountered.... and so on). In addition I have a...

Hi there, I had to create a samba server with shadow copy support, so I needed a fs with snapshot support and I thought to use BTRFS which is well suitable for this purpose (I used it before on bare-metal installations). Since it's a COW filesystem like ZFS, I was wondering if it could cause...

Hello everybody, I'm looking for a reliable way to backup ZFS zvols of my proxmox system. Since the built-in vzdump tool is pretty slow, as it always create full dumps of each virtual disk wasting a lot of disk space (no plans for qemu incremental backups yet? -...

Hello everybody, Currently, I've got a proxmox node with fiber channel SAN storage (I'm using LVM here) and NFS on a Synology NAS. Since I've got another two smaller spare servers available, I would like to put a FC HBA card on them and create a 3-node cluster, but I don't want to keep these...

Hello, I'm experiencing an annoying issue with virtio networking under linux guests (mostly CentOS 6, 7 and RHEL derivates such as Oracle Linux 6). It happens that after a while (even days) the vm is up and running, it looses connectivity to the network and I need to change NIC to e1000 and...

Hi everybody, I'm going to install proxmox on one node with a FC SAN (I would like to add another node in future), but I just have some concerns about which storage backend to use. I really like ZFS and I would like to use it on my SAN, but I don't have RAM to give it and I'd prefer to use my...

Hello everybody, I'm planning the migration from our current virtual environment from VMware ESXi 5.5 to Proxmox. I need to migrate VMs from main server to a temporary server, install proxmox on the main server, and then move VMs back in there. Since now I have a FC-SAN available, here's what I...
