I don't use HA. The cluster has more than 2 nodes; does it make a difference?

Hi, I always disable IPv6 on all servers, since I don't use it (yet). I wonder what other users are doing with IPv6: (1) disable it since you don't use/need IPv6; (2) enable it and and use it actively since you need it, or find it useful; (3) don't do anything with it, just keep the default...

thank you @aaron for your answer. Since the extra NIC and new network is dedicated to inter-node traffic only, I assume I don't need a bridge for it because no VM would be ever connected to that bridge. Is is correct? I am also worried about this: if a node is disconnected from the cluster for...

Hi, many of us run Proxmox VE on servers hosted by Hetzner. The network configuration is usually the most tricky part. I am going to post my network configuration here (real IPs changed). I hope it could help people in a similar situation. I also hope to get some feedback and constructive...

Hi, I have a Proxmox cluster at Hetzner (no shared storage). I use a feature supported by Hetzner called vSwitch which let customers connect servers via a virtual private network across different locations. My Proxmox nodes at Hetzner are inter-connected (joined) via a private subnet on a...

thank you for the prompt answer.

Hi, on pve hosts when I run ip l, I see a lot of tap devices. How can I figure out the VM corresponding to a specific tap device, for example tap123i0? I have setup netdata monitoring on the pve host, and it reports that a tap device has been dropping packets. But I don't know which VM is it.

Hi, yes I have learnt that qcow2 on top of ZFS is not the best way to do that and had to convert all VMs to ZVOL. Thanks to Proxmox GUI it was not painful as it would be. re. 3-way mirror: I wanted to have some peace in mind, and have seen some recommendation to go for 3-way mirror. It's...

Hi, I have been running ZFS on Promox for a while and in general I am very pleased with it. I would like to share my (relatively new) experience with ZFS and hope to hear experience from other users. I have a server SX132 at Hetzner with 10x 10TB disks, 1 zfs pool of 3 Striped 3-way Mirrored...

yes I did destroy VM 103 (and other VMs that I tried in-between) yes the VM was created very quickly with a single short error: qmrestore /backup/vzdump-qemu-123-2019_11_04-18_35_26.tar.lzo 999 --unique --storage local VM is locked (create) ah yes, indeed. Thanks a lot. Regards, Tony

Hi Thomas, thank you for your hint. I have tried the following: # qm config 103 Configuration file 'nodes/hn5/qemu-server/103.conf' does not exist # pvesh get /cluster/nextid 103 I have also tried with various IDs, but the result is always the same: vm created but disk not imported...

Hello, I am having this problem and could not find any hint on this forum. I have also googled for a while without success. I have a proxmox server 2.X with a few VMs running on it. Now I want to move the VMs to a 5.X Proxmox server. I did the following: - create a backup on the old server...

thank you for your answer, very much appreciated. Regards, Tony

Hello, I am planning for a new Proxmox VE server and would like to ask for your opinions/comments. It's a server with 64G RAM and 2x500G SSD, for about 4-6 CTs running java apps, no VMs. Plan: - partitioning for /dev/sda: /dev/sda1: 20G, type mdadm, used for: mdadm raid1 for rootfs...

Hi, the title says it all. We are considering to move a monster web application from a physical host to virtual machine, and I wonder if openvz fits the bill. I have been using openvz for years, however I didn't have any virtual machine that scale (32-64G RAM, with Tomcat/JBoss/Oracle running...

another useful tip! many thanks. Tony

Hi Marco, [sorry for the late reply, could not catch things up] many thanks for those useful hints; much appreciated. it seems like in case (2), migrating all VMs to the 2nd node and reinstall the crashed node is the simplest way. I will stick with this plan then. Regards, Tony

Marco, thank you very much for the *great* answer. Exactly what I was hoping for. Regards, Tony

Hello, [I apologize if my question has been answered before. I was searching the forum and wiki but could not find a concise answer]. I plan to have a cluster of 2 nodes, no HA/DRBD, latest proxmox VE. Can someone please briefly highlight the steps what to do if: case (1): I want to shutdown...

the following works for me: - do not use inetd at all - in eg /etc/pve/local/qemu-server/100.conf: add this line: args: -vnc 127.0.0.1:3100 - how to connect: # on node: qm start 100 # on my laptop: ssh -L 30100:localhost:9000 node-IP # start TigerVNC, connect to localhost:30100
