UdoB replied to the thread PDM: migrate VMs across firewall.There is no additional PVE involved ;-) The "external relay" is just a common reachable rendezvous point to establish the tunnel. All payload traffic would then go through this device, which vastly influences the reachable bandwidth... -
Hi, There are 2 issues in your config - the main issue is MTU flapping. KNET's Path MTU Discovery runs globally across all links. When a node rejoins on link 0 (eno1, MTU 1500), KNET resets the global PMTUD process for that link. While it's...

UdoB replied to the thread PVE9 VM suddenly stops when finishing backup to PBS.I would further slow down. My goal would be to adjust to the speed the PBS is actually capable to absorb - to keep the fleecing file small. If that runs stable I would (relatively) slowly increase the bwlimit. Just my thought... and a very slow...

Sind aber fester Teil der IT seit ewigen Zeiten. Und nicht auf x86-64 beschränkt, worüber seinerzeit Linus Thorvalds in Bezug auf arm (1) schimpfte: https://lkml.org/lkml/2012/7/15/133 Und in folgenden Skript zur theoretischen Informatik... -
Hi, portforwarding on the firewall should also work, and exposes only the required port, instead of the host (to the other host). This would also cause lesser computational overhead for wrapping the package content. On the other hand there is...

UdoB replied to the thread PDM: migrate VMs across firewall.My personal choice would be to establish a Wireguard tunnel. My preferred method is to handcraft something like https://www.wireguard.com/quickstart/. But this requires one endpoint to be able to reach the other one; in a single direction is...

UdoB replied to the thread Proxmox installing to incorrect nvme disk.My thoughts: Erase both disks. Completely! (If you just delete partitions some signatures may still be present.) Use any rescue image to boot and run something like "dd if=/dev/zero of=/dev/nvem0 bs=1M status=progress" for both of them. Remove...

UdoB replied to the thread Was soll der Architektur-Eintrag in den LXC-Optionen?.Und das war ein Fehler. Es suggeriert aktiv, dass es keine anderen Hersteller gab/gibt. Doch. Es weist nämlich darauf hin, dass Zellstofftücher nicht unbedingt "Tempo"-Taschentücher sind. ;-)

UdoB reacted to TrevorW's post in the thread [SOLVED] No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync with Like.
Ok looks I like I got it solved and the trick was to unmount /dev/sda2 and then run the proxmox-boot-tool init command. root@Proxb2:~# umount /dev/sda2 root@Proxb2:~# proxmox-boot-tool status Re-executing '/usr/sbin/proxmox-boot-tool' in new...

Feature requests sollten am Besten im Bugzilla gestellt werden, hier im Community-Forum gibt es keine Garantie, dass Entwickler alle lesen. Der Bugzilla-Tracker wird dagegen gemonitored: https://bugzilla.proxmox.com

Hi Eric, just reiterating what @bbgeek17 said. MTU of 9000 for your NAS traffic is beneficial, IFF you set your NAS storage interfaces to 9000, the ports they are connected to on the switch at 9000, and all the clients have an MTU of 9000...

You can also run the qdevice as vm or container on the PBS if you install a PVE and PBS on the same host without adding it to the cluster: https://forum.proxmox.com/threads/2-node-ha-cluster.102781/#post-442601 In the case of the OP I would go...

As others have mentioned, it is technically possible to set size=2 and min_size=1, but it does come with risks. From a Proxmox and Ceph perspective, this configuration is not recommended. While it may not be explicitly unsupported, the fact that...

UdoB replied to the thread [SOLVED] No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync.Not sure. Touching the boot process is always... delicate. (Make sure to have a "plan b", where "b" stands for "backup" ;-) ) On my systems "/boot/efi" is not mounted. That makes sense as the content is not relevant after a successful boot and...

You are welcome: I noticed that I missed to link the thread where lnxbil described his way to use special_small_blocks, so I edited my post to link it: https://forum.proxmox.com/threads/zfs-metadata-special-device.129031/post-699290 Please note...

UdoB reacted to _gabriel's post in the thread How to dismount and remount USB drive for manual backups on PVE with Like.
if device is not mounted, backups are written to / filesystem. umount and delete backups if they exist in the mount point. use chattr +i /mnt/.../proxback to prevent its usage when mount is missing.

UdoB reacted to MarkusKo's post in the thread Help with Network Configuration for first time user with Like.
Looks good. Not sure if you need a LAG for Management, you could just assign a differnet subnet to each of the adapters, less complexity. Don't forget to add a qdevice or you will get issues with your 2 node cluster. And for PBS, it is...

UdoB replied to the thread RAIDZ-1 PBS Mismatched Disk Sizes.You can make this work on the CLI, see man zpool-create: The use of differently-sized devices within a single raidz or mirror group is also flagged as an error unless -f is specified.
