Hi all, First, I wanted to thank the Proxmox Team for their work on PDM, as this tool will certainly help us to manage our multiple clusters / PBS across datacentres. Now, I'm playing with this in the lab, and was wondering what were the mandatory permissions in order for PDM to work? As I'm...

Bonjour all, I've upgraded a lab node to PVE9 today. Everything went well until it didn't. This lab setup uses a virtual router for its networking. On reboot, the VM failed to boot with this error : WARN: no physical CD-ROM available, ignoring kvm: -blockdev...

Hi all, We've (finally) decom'd an old PBS which also had an NFS share from ancient (PVE 5.X) times. To my surprise, however, my PVE backup scripts started failing (well, after I remembered those existed and switched them to the new PBS). They were stuck on the /mnt/pve/ directory. In here...

Hi all, Following https://forum.proxmox.com/threads/hard-drive-strategy.137806/, We've managed to convince the bean counters to allow us a bit of money to get backup servers. Now, the configuration I got is a bit different from the suggested configs in the previous threads. For now, we've...

Hi All, Happy new year! Best wishes to everyone. I have been trying PDM to see how it could fit our proxmox deployments. So far, I have 3 VMs, two PVE and one PDM. Everything seems to be working fine, but it appears nodes need to be able to talk to each other to migrate VMs. Is there a proxy...

Hi all, We've (finally) got a long-term storage, centralised, last resort PBS where all the other PBS go and dump their backups into. I want to add a Read-only account of which every cluster will have a token of, so that in case of a disaster recovery process, I can restore backups from this...

Hi all, A bit of a weird one here, leaving this here in case anyone finds themselves in the same boat as we did. Colleague installed a VEEAM backup on a clean installation of Windows Server 2019, wanted to add a Dell DD6400 Data domain as a repository. This was already working on another VEEAM...

Hey all, Currently testing CEPH and Proxmox HA on a multi datacenter configuration (with black fiber, so sub ms latency.) I tried to recreate the worst scenario possible : what if all nodes lose the corosync layer? This should never happen, but that's what the lab is for. I'm using Proxmox...

Hey all, I'm trying to clone some backups to a new datastore the "good" way (using local sync instead of copying files and forgetting to chown them). However, I can't seem to select the source datastore : The source datastore menu is empty, and I can't select anything. Permission wise, my...

Hey all, I'm seeing a weird behaviour on one of my PBS node. The GUI verify job which should run every day has been failing for a few days now. Upon further investigation, the verify job is trying to verify a non-existent (probably pruned) backup : (datastore name has been censored but isn't...

Hey all, Continuing on my journey to create a somewhat good Proxmox Backup Server infrastructure for my company, I'm now considering different hard drives configuration, but am a total noob when it comes to high (for us) quantity storage. As of now, the idea would be to have around 100Tb of...

Hey all, I've got the opportunity to upgrade the Proxmox backup servers running in our production environment. Currently, I have the PBS set up as follows : DC A backups to the PBS on DC B DC B backups to the PBS on DC A DC C backups to the PBS on DC A I am fully aware that this is not...

Hey all, I'm trying to use an old Dell VNXE Storage as a sync target for cold storage out of site backups copy. The datastore creation fails with an IO Output error. As it turns out, it seems I cannot create more than 65533 folders : root@definitelynotwhereiam-pbs2:/vnxe/.chunks# mkdir foo...

Hey all, Foremost, I am aware that backups on NFS shares aren't the way to go. This is experimental, but I'd still like to share this issue. We're running a PBS that has an NFS Share on a Dell DD6400. As the PBS doesn't support the ddboost protocol, we're using the NFS feature to store...

Hey all, I'm stumped on an issue, and at this point the only explanation I have is black magic. I have multiple PVEs on different sites. For backups, they all share a common layer2 VLAN. They all can see each other, and ping each other. SSH works, but SFTP / RSYNC fails between 3 specific...

Hello all, I'm having issues provisioning our new pve with our own certificates; Upon installing them via the web interface, the pveproxy service fails with this error : pveproxy-ssl.pem: failed to use local certificate chain (cert_file or cert) at /usr/share/perl5/PVE/APIServer/AnyEvent.pm...

Hello all, A few weeks ago, I've finished the second version of the home lab, mainly out of power efficiency concern. I now have 2 nodes in a cluster. One is a Gigabyte BRIX nuc like, and the other one is custom-built. That last one is giving me trouble. The symptoms are as follows : — The...

Hey all, I'm in the process of setting up a Mikrotik CHR (Virtual Router) for routing 10Gb network traffic. However, testing with EXFOs has shown that, with random packet size, I am not getting anywhere near 10Gb/s (I'm getting around 6Gb/s average, should be closer to 8Gb/s). I've tried...

Good day all, I've found that my PVE has crashed tonight. I've lost all monitoring at 0150, and the host has been in limbo since. Not only that, but I had run apt upgrade yesterday, so this might be related. SSH isn't working, nor is the GUI. I can log in to the console, but I cannot get a...

Good afternoon, We are currently looking into finally upgrading our clusters to Proxmox 6. As such, I've been using the guide to this effect, and it has worked great with Proxmox 5.3. However, We have a cluster of 3 Proxmox 5.1 nodes, and I would like to set up a test cluster to see if...
