Sskraw replied to the thread Problem with zfs and setfattr.Hm, does not sound like you understood the problem setup. Maybe I did not explain well. I have a VM backup guest. This is the destination for numerous rsync backups from _elsewhere_. The advantage in using rsync is exactly to be able to access...

Sskraw replied to the thread Problem with zfs and setfattr.Ok, I did not think about that so far, is it possible that the problem is related to apparmor on proxmox?

Sskraw replied to the thread Question regarding memory hotplug and numa.Hi Jonas, thanks for your comment and the referenced articles. From reading them and personal experience I'd say this topic needs qualified re-programming in proxmox. To me it seems obvious that hotplugging is a key-feature in virtualised...

Sskraw posted the thread Question regarding memory hotplug and numa in Proxmox VE: Installation and configuration.Hello, recently I had some troubles with client vms that needed a lot more memory than expected. This brought up the idea to switch on memory hotplug for such vms. So I enabled numa and mem hotplug and tried to give the vm a bit more memory from...

Sskraw replied to the thread Problem with rsync mtime preservation since update to kernel 6.17.13-6-pve.And now the problem came back, again for no obvious reason. rsync on nfs-mounted zfs and the mtime is set to current time, which it is not if I do the same rsync on a local drive with ext4. Any ideas?

Sskraw replied to the thread Problem with zfs and setfattr.First of all let me say thank you for the time you take to answer in this thread. Unfortunately this does not quite make it to a point where I want to go. Since the backup host is exactly the same as it was when using a local ext4 drive. So I...

Sskraw replied to the thread Problem with zfs and setfattr.Well, in fact I am coming from another side to this problem. I take backup by rsync from a lot of hosts. when the backup drive was built into the backup server (with ext4 fs) everything went without problems. Now I virtualised the backup server...

Sskraw posted the thread Problem with zfs and setfattr in Proxmox VE: Installation and configuration.Hello, I just came across a problem with zfs handling of xattrs. My zfs has xattr=sa and is mounted with xattr. But using setfattr on a file results in "operation not supported". Why is this?

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...
