Sskraw replied to the thread shrinking qcow2 image virtual size.Ok, i found another thread with quite the same problem showing up: https://forum.proxmox.com/threads/trying-to-shrink-qcow2-image-to-make-space-for-another-one-on-the-proxmox-host-image-gets-corrupted-after-resize.119920/ Only he tries to...

Sskraw replied to the thread shrinking qcow2 image virtual size.sometimes the real problem hides behind a simple question. In the meantime I found out that qemu-img resize does not work but shoots the disk resized, no matter how few bytes you shrink it. How about that?

Sskraw posted the thread shrinking qcow2 image virtual size in Proxmox VE: Installation and configuration.Hello all, I have to move around some physical boxes and virtualise them later on. So I came across this question about qcow2 images and cannot find a conveniant solution for it. Lets assume having a qcow2 disk image with a big virtual size and...

Sskraw replied to the thread Problem with rsync mtime preservation since update to kernel 6.17.13-6-pve.Now, I investigated the problem further and got the impression that the kernel on client and server side must have some influence. The problem arose after a proxmox kernel update. My client kernel with problems was 6.12.something. I had another...

Sskraw replied to the thread Problem with rsync mtime preservation since update to kernel 6.17.13-6-pve.Ok, to make the story a bit simpler. You are right, the problem turns around mtime. But you seem wrong about the rest. If I do an "ls -l"' on the source dir of the rsync I see some dates/times for every file. These are of course mtimes. If I do...

Sskraw posted the thread Problem with rsync mtime preservation since update to kernel 6.17.13-6-pve in Proxmox VE: Installation and configuration.Hello, it seems I see a problem with my proxmox based nfs server (on host) on a zfs volume in conjunction with a nfs-client using rsync. Once a month I copy some files with rsync -avxAHX from some place to a nfs-mounted fs coming from a proxmox...

Sskraw replied to the thread corosync show link flapping (down/up) about every 3-4 minutes, but switch shows no problem.No, I don't have a fine-grained monitoring, and really, this is not exactly the point. I am very sure that all your working nodes are built on an empty network, just like the proxmox doc for corosync says. The thing is this: if I have even an...

Sskraw replied to the thread corosync show link flapping (down/up) about every 3-4 minutes, but switch shows no problem.Just to make that clear again: the networt link is not saturated. Monitoring shows an average of around 400 MBit/s on a GBit interface. Which means it is quite far away from a bandwith problem. So the real question here is: why are packets lost...

Sskraw replied to the thread corosync show link flapping (down/up) about every 3-4 minutes, but switch shows no problem.kernel is 6.17.13-2-pve, exactly the one pve-enterprise installs. The modules is indeed available Thanks

Sskraw replied to the thread corosync show link flapping (down/up) about every 3-4 minutes, but switch shows no problem.I wanted to try the problem situation with a bbr congestion variant. But I found that the kernel delivered with proxmox does not supply this congestion protocol. Why is this?

Sskraw replied to the thread corosync show link flapping (down/up) about every 3-4 minutes, but switch shows no problem.That is not the complete truth. Look at this: --- 192.168.192.250 Ping-Statistiken --- 14000 Pakete übertragen, 13862 empfangen, 0.985714% packet loss, time 14133836ms rtt min/avg/max/mdev = 0.103/1.065/3.615/1.127 ms This is quite a long...

Sskraw replied to the thread corosync show link flapping (down/up) about every 3-4 minutes, but switch shows no problem.No, the fiber link is dedicated, the copper is also used for other purposes. I checked that in detail and had to find out that the latest kernel networking is not really as good as one might think - after all those years. If there is nfs traffic...

Sskraw replied to the thread corosync show link flapping (down/up) about every 3-4 minutes, but switch shows no problem.There is definitely no address conflict.

Sskraw posted the thread corosync show link flapping (down/up) about every 3-4 minutes, but switch shows no problem in Proxmox VE: Installation and configuration.Hello all, I recently experience a problem with corosync showing link flapping, but it seems to me that these are really fake. Neither the corresponding switch shows a link problem, nor the kernels of the boxes (3-box cluster). I use a 10G fiber...
