The reason for the verification error is some missing or broken file. The backups on server A are done to a SAN and the SAN seems to have a problem from time to time. My guess is, that it becomes unavailable during backups and then the backup becomes corrupted. So even a re-verify fails because...

I have a two server setup PBS where server A is located within a proxmox cluster and recieves the backups for the proxmox VMs. Server B is geographically separated and has a sync job to the datastore on server A. (the backups on A are transferred to B). This setup works fine, as long as there...

There is another trick which I use on all Windows VM installations. In the step where you load the disk drivers from the virtio CD, you can also select other drivers, like network dirvers, and install them. I ususally install all drivers here and only then continue the setup.

For anyone having the same issue. I managed to import the VM from GCP like this: - Export it from GCP as qcow2 file. (Create an Image then export this to a bucket then download the file from the bucket) - Create a Linux VM in Proxmox and assign it a (small) HDD in qcow2 format. - go to VM...

Obviously all the data needs to be transferred. But zfs uses block-based compression and achieves such a high compression rate. I would expect the migration to also use compression and achieve a similar, if not bigger, compression rate. Obviously no compression is applied. Viewing a Proxmox...

I think I stumbled uppon a bug related to container migrations. I have a container running on zfs storage with compression enabled. It's a test server which produces huge amounts of logfiles, which are highly compressible. The disk usage is 250 GB but the referenced size is around 3.000 GB. A...

I am having the same or a related problem, but my dmesg is empty, no errors about hangs or anything else. I narrowed it down to the following. Each PVE Node has a dedicated network card which is used only for Link 0 in the cluster. They are connected to a simple gigabit switch which only...

I am having the same issues with PBS and do not yet understand the dirty-bitmap topic. Let me ask a more specific question: How should I do the backups in order to have (a) consistend backups and (b) make use of the dirty-bitmap feature. If I configure the backup mode to be "Stop", will this...

Thx for the answers. PBS and `qm remote-migrate` seem to be very reasoanable options.

I don't know how this tool would help me. How does it connect different clusters to each other?

I want to use Proxmox at two different locations. My question is how can I connect them to each other? We already have small PVE cluster at our office. This is ideal for development and testing but not suited to serve the public (internet connection to slow, not enough IPs, etc.). The plan is...

@krikey thx for your work. I tried your code and it works nice for smaller CT/VMs. But for lager VMs its waaay to slow (on my machine). I came up with a different approach for VMs. a) VMs are backed up in fixed-sized chunks of 4 MiB. (According to...

I am having some problems with one of my VMs. The dmesg is full of "Out of puff!" errors while the host never got close to running out of memory. Any idea why this happens? [Mi Mär 15 01:10:59 2023] kworker/2:0: page allocation failure: order:0...

I have been using PVE for some years and I want to also use PBS now. It seems like I don't quite get some of the concepts. My setup is: one PVE cluster and one PBS on a separate physical machine. The PBS has 1 SSD as boot drive (with zfs) and a raid-z2 array of 6 HDDs for storage (called...

I am using netdata to monitor my PVE hosts. On some of them I am getting inbound_packets_dropped_ratio warnings because 2 % of packets are dropped. Any idea why? Here is my setup: Each host has 2 NICs, first is mapped to vmbr0, second to vmbr1. vmbr1 is only used for PVE traffic. It is...
