To be on the same page, none of this is PVE specific. You are dealing with basic Linux network management. At one point in the thread you mentioned that there is a "direct" connectivity between the clients, is there an actual direct cable? Your... -
UdoB replied to the thread Proxmox 8 to 9 introduced LXC terminal problems.When logged in, try reset. (If this sounds risky: read man reset.) I have no idea what triggered that behavior, but "reset" should re-initialize the terminal with sane values. Disclaimer: I do not use containers...

Looking at the screenshot, Prunes is 0 for both datastores. Are you sure you have set this up correctly?

What you want for an OS/VM pool is random Read/Write IOPS. Striping your drives will always be faster than mirrors/RAIDZ (speed vs. reliability/parity..) but having drives with good random IOPS makes a much bigger difference. Practically this...

raidZ1 is known to not be good for IOPS: https://forum.proxmox.com/threads/fabu-can-i-use-zfs-raidz-for-my-vms.159923/ . And your drives might be consumer drives without =1&c[nodes][0]=16&o=date']PLP. Lots of threads about disappointing (write)...

Like.
Hi, I have wrote a script to generate an iso install with debian + proxmox package merged + debian preseed file for automatic installation, with crypto lvm + specific partitions for CIS compliance. It's using secureboot with proxmox shim &&... -
UdoB reacted to jdancer's post in the thread ZFS with PERC H745: is RAID0 the same as JBOD? with Like.
On 13th- & 14th-gen Dells PERCs, have to delete the virtual disks before switching it to HBA-mode. Call it a quirk. I've also had issues with the megaraid_sas driver in the past, so I just swap out the PERCs for Dell HBA330s, which is a true...

Purpose Inspired by Level1Techs, I decided to replace my old router with a single box solution that's flexible, upgradable, and efficient. That includes using Proxmox to utilize spare resources without interfering with the vital router...

UdoB reacted to awado's post in the thread [SOLVED] Kein TOTP-Login mehr möglich nach Zeitfehler with Like.
Ok, dank KI & OpenCode konnte ich die Ursache jetzt doch selbst finden (lassen): In "/etc/pve/priv/tfa.cfg" wurde der Zugang gesperrt mit …"totp-locked":true… . Wenn man dort das auf "false" setzt, geht es wieder. Ich lass den Post mal so stehen...

UdoB reacted to JD-iteee's post in the thread [SOLVED] Making best use of multiple NICs per Node with Like.
Hi Maxim, with 4x 2.5GbE per node and your setup using Corosync, HA and ZFS replication without Ceph, I would separate the traffic types as much as possible to keep the cluster stable and easier to troubleshoot. I would use one dedicated NIC...

UdoB reacted to MarkusKo's post in the thread [SOLVED] Licensing for nested PVE on single host with Like.
With one community subscription you can only license one PVE with one socket, the physical host would be the best choice. For testing and playing around you don't need a subscription at all, just use the no-subscription repo. You will have to...

the behaviour is intentional and a security feature - each newly created snapshot is only allowed to re-use chunks of the previous snapshot, for other chunks it has to "prove" that it actually has that chunk by uploading it. PBS (as opposed to...
