Hi there, I'm building a new 3 node PVE cluster. I already have a full mesh prepared for live migrations, Is it possible to use this full mesh as a failover network for the cluster itself? In the WebUI at "Create Cluster" it doesn't seem to be possible to add both mesh links. Thanks and greets!

Hi, after almost five years with our three node PVE/Ceph cluster now it's hardware renewal time! Core requirements are: - about 24 TB of usable storage (fast and scalable) - about 512 GB RAM per node (scalable) Unfortunately we can't go with AMD EPYC CPUs because of Oracle. Together with...

Hallo zusammen, wir sichern unsere ca. 60 VMs auf einen dedizierten PBS. Nun würden wir gerne einen weiteren PBS als Offsite Backup an den Start bringen, der einmal am Tag das jeweils jüngste Backup aller VMs zu sich holt. Sowohl die Einrichtung, als auch der initiale Sync haben prima geklappt...

Hey there, our vulnerability scanner recommends us to disable TCP timestamps. Is it safe to do so on PVE/Ceph, PBS and PMG? Thanks and greets Stephan

Hi there, we received a solicited mail that doesn't contain a body tag. And there is a file attached. PMG classified the mail as spam (which is not a problem for us). PMG's WebGUI (Administration -> Spam Quarantine) says "unable to parse mail", and at the bottom of the window there is "No...

Hi there, our vulnerability scanner recommends us disabling answering VRFY and EXPN requests by configuring disable_vrfy_command=yes Is it safe to do this in a PMG installation? Thanks and greets Stephan

Hi there, we just upgraded our PBS to version 3. And we run a couple of Debian bullseye systems with Proxmox Backup Client. Is it safe to change the Proxmox repo to bookworm on a bullseye system, or should we wait until we upgrade the entire system? Thanks and greets Stephan

Hi everybody, we must build a new storage for our backups (see https://forum.proxmox.com/threads/zfs-raidz1-expanding-not-possible.127480), so I would like to copy our backups (about 30 TB) to another storage, build a new ZFS pool, and put the backups back. I successfully rsync'd...

Hi there, a few months ago we built up a new PBS with a bunch of U.2 NVMe. I naively thought ZFS must be the way to go creating the storage for the datastore. So I created this storage: # zpool status nvme-pool pool: nvme-pool state: ONLINE scan: scrub repaired 0B in 04:34:39 with 0...

Hi, since a couple of months we have a PBS which works like a charm! It's a dedicated server hardware with a bunch of U.2 NVMe disks, one datastore with five namespaces and different retention strategies. In total about 42 TB of backup data - upward trend. :) Now we would like to do some kind...

Hi there, since a couple of weeks we're testing PBS to be our future backup solution. So far, so great! :) For some minor topics I would like to look for answers here - here we go: Currently we focus on backup the VMs running inside our 3-node-PVE/Ceph cluster. From the beginning we threw...

Hello everyone, today we upgraded our three node PVE/Ceph cluster from 7.1 to 7.2. The first attempt of apt dist-uprade ended up with Errors were encountered while processing: /tmp/apt-dpkg-install-0DYbqq/46-libproxmox-rs-perl_0.1.0_amd64.deb E: Sub-process /usr/bin/dpkg returned an error...

Hi there, we're planning a new backup server (migration from Bareos to PBS) including new hardware. Therefore I would like to throw the following setup into discussion: https://www.thomas-krenn.com/loadproduct?id=y4cd0fdaaa218617b&lang=de in short: CPU: 1x AMD EPYC 7343 RAM: 64 GB DDR4-3200...

Hi there, we would like to have a file based backup of our three PVE/Ceph nodes. The goal is to have everything needed to bring back one or more nodes from zero to the current state (except VM data of course). What do you suggest which files and directories we should backup? Thanks and greets...

Hi there, yes, I know - not exactly a Proxmox VE question... But maybe someone already solved this problem or have at least ideas what we could try. Here we go: On one of our PVE nodes we run a Windows Server 2016 VM (KVM) as a remote desktop services server - and we're very happy so far...

Hi there, today we like to install updates on our three nodes of our PVE/Ceph cluster which need restarts. # apt list --upgradable Listing... Done ceph-base/stable 14.2.6-pve1 amd64 [upgradable from: 14.2.4-pve1] ceph-common/stable 14.2.6-pve1 amd64 [upgradable from: 14.2.4-pve1]...

Hi there, we just started with our three node PVE/Ceph cluster - so far so good. Now I'm looking for the best way for "disaster recovery style" backups of our Windows and Linux VMs. At the moment we do backups like this: For file based backups we use Bareos which works well. For (weekly)...

Hi there, we have seven SSDs behind the HBA mentioned above. How can I find out the mapping between a physical slot and the disk inside Proxmox VE/Debian Buster? A long time ago I used storcli, but I can't find it anymore. Is this tool deprecated? Do you know other tools to handle this? Thanks...

Hi there, is there a way to put the proxmox backup on a seperate network (interface)? At the moment it seems that it's going through the same network as the management GUi - and in our case this is just 1GBit/s, while there are 10 GBit/s possibilities waiting for work. :) Thanks and greets Stephan

Hi there, I did a reinstall of my three node PVE/Ceph cluster, and now I would like to clean up the OSDs so that I can use them again as... OSDs :D. Lately I found a nice command for this task, but I can't find it anymore. Can you help? Thanks and greets Stephan
