I'm planning to set up two PMGs in front of my Carbonio Mail Server (the one that "formerly Zimbra"). My goal is to make the PMGs fully autonomous, so that even if the mail server goes down, the PMGs can continue to receive emails and forward them to Carbonio once it's back online. To achieve...

I found InfluxDB Cloud service and they even have free tier (pay as you go but retention up to 30 days seems to be free), and I really wonder if someone tried this. I tried to connect my lab server and have no success, but I'm not a pro with InfluxDB. The idea I have is that even with lab...

I have LXC container on PVE host, and initially it was assigned one WAN IP and one LAN IP (LAN IP is internal subnet to reach other VMs on PVE host). It was configured via web and this is how it looked in the config: net0...

I have PVE host running for 5+ years. It was set up on couple of 2Tb HDDs in zfs mirror, and now it's time to change these disks with newer ones. I brought 10Tb HDDs, and plan the following: - partition new disks so it has layout of old 2Tb disks, but the last partition will accomodate all 10Tb...

It is very great news about PVE 8.2 realeased with its ESXi import feature. May I please ask when it can be possible to see feature of auto migration of VMs from overloaded PVE nodes in cluster? This is something that's very useful on vCenter cluster. Thanks again for your work!

I have a server, which equipped with 2 x 2Tb HDD and 2 х 512 Gb SSD disks. I'd like to install PVE 7.0.2 on it, and plan to create mirrors out of these disks. So, I really doubt, if I should install PVE (OS) itself on SSD ZFS mirror or on HDD ZFS mirror? Both approaches are appears to have its...

All of my previous experience of PVE setups related to stand-alone hosts, and PVE is perfect for that. Now we want to connect shared SAN storage to several PVE hosts to have HA available. SAN (we rent it) seems to be FC connected. At the same time we want to have the same VMs copied...

I used to use standalone PVE hosts, with local attached disks. Nice and tiny setups :) Now I have a chance to set up PVE cluster with shared storage. It involves some like 2 groups each consists of "6 hosts and 1 SAN". All hardware to be rented so we can make some adjustments at this point...

I have handy server I can play with (but not to kill it). Its /etc/apt/sources.list looks this way: deb http://ftp.debian.org/debian buster main non-free contrib deb http://ftp.debian.org/debian buster-updates main non-free contrib deb http://security.debian.org buster/updates main non-free...

A friend of mine have set up a host for webdev purpuses and after my advice used fresh PVE instead of initialluy choosen Hyper-V. The host is at datacenter, and they provided only one IPv4 address, and renting more is a bit tricky there. So, my friend installed nginx at Proxmox host itself...

Dealing with several PVE hosts, all of them are standalone, I want to know disk of each VM in some algorithically easy way. The problem that, some of VMs are raw or qcow2 files, some are stored in zfs volumes. I suspect I can only scan /etc/pve/qemu-server/*.conf files for virtio/scsi/ide/sata...

I have single PVE server (6.4, community repo) and I noticed It has constant iodelay > 0 even when host is almost idle. The host is very low loaded, so not expected to see that. There is single m2 NVMe disk on board (Samsung 970 EVO Plus) installed mostly as a test disk, and couple of Intel 545...

I got a bit unusual question related to virtual CPU as it seen in VM. I need to copy VM with some rare and licensed software from old PVE host (4.x, and old hardware) into new one (PVE 6.2, much newer hardware). The software itself bound its license to id string consists of CPU info bits...

I try to use pve-zfsync to replicate a VM, and so far it looks quite good. The VM itself is a Cenos 7 with nginx/apache/mysql web site server. My concern is, while data VM disks will be replicated nicely, the data in the VM's RAM (mostly MySQL data) won't be transferred so the replicated VM may...

Planning to implement pve-zsync to do regular (routine) off-site VM replication, and it looks like I understand all my backup steps but can’t figure out the recovering steps: It says, first, I need to disable the replication for VM. Ok, that's understandable. Then, I can “send the VM or...

I use Supermicro server with PVE 6.2. I did the watchdog setup this way: /etc/default/pve-ha-manager: WATCHDOG_MODULE=ipmi_watchdog /etc/modprobe.d/ipmi_watchdog.conf: options ipmi_watchdog action=power_cycle panic_wdt_timeout=10 /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet...

I have several KVM VMs on PVE host (both windows and linux guests), all VMs are have qemu-agent installed, and PVE web interface show VM’s IPs. But I can’t find a way to get these IPs from script run on PVE host. Please advice! Should be some API call or some way to poll qemu-agent I suppose...

Just read in the news that OpenZFS is introduced. Any plans to use it in the PVE 6.4 (?) or maybe it will be possible to use it as it be delivered over Debian upgrades?

As we moved to PVE 6.2 (just several hosts, not huge install), we noticed that Windows server VMs we used to run on PVE are to see sudden NIC stop working. The fix is really simple: set NIC to not connected (no link) in PVE web interface, apply changes, the connect it again and apply again - all...

As I try to gather PVE node stats with Zabbix I found I can not get real port usage for physical port that faces the WAN link. Vmbr0 stats seems to show only own node usage, but I need whole link usage (own node plus all of VMs usage). Silly question I know but can’t fond a way. Vmbr0 vs switch...
