Llslamp replied to the thread IO Pressure Stall - Unexplained.ok I have been pretty busy trying to understand what is going on. I have a VM 101 see below. I created two clones of this VM canned then 109 and 110 I have VM 109 below On VM 109, the only change I made was select Discard under Disk Config...

Like.
Es gibt halt keine echte Empfehlung, weil Proxmox VE nicht für diesen Anwendungsfall konzipiert wurde. Die Empfehlung lautet daher, es eher nicht zu tun. Aber wie andere bereits gesagt haben ... Es ist Debian, da geht vieles. Probiere es halt... -
Iiay replied to the thread [SOLVED] Performance drop-off after upgrade from Proxmox v8.4.19 to v9.2.1.It turns out that I have a couple of weeks of Prometheus metrics for this node. Both the CPU pressure stalls and I/O pressure stalls started at the upgrade to PVE 9 and were not present in PVE 8. The CPU pressure stalls seem to be related to...

I think you're asking the wrong question. what is the workload in vm count and minimum required iops/vm? how much capacity do you need? ceph works fine with hard drives. its just slow. -
We will re-evaluate it, but cannot make any promises. What we also look into periodically is reducing the attack surface in general, like we started rolling out some simple but relatively effective approach to block autoloading of various niche...

The deprecation itself was not strongly influenced by that, but the decision to communicate it more actively was in fact primarily driven by it. Normally, we only mentioned it on the side once a new kernel became the default. In the past, we...

justinclift replied to the thread Ceph flapping OSDs - OSDs only using public network not the cluster one.As a workaround for now, I've set the "nodown" and "noout" flags. That's allowing things to actually work "ok". A real solution would be preferred though.

justinclift posted the thread Ceph flapping OSDs - OSDs only using public network not the cluster one in Proxmox VE: Installation and configuration.Having a super weird issue with Ceph (squid, 19.2.4) today. The OSDs are flapping (ie not talking to each other) and I have no idea why. I changed the PCIe network card in each node of my small 3 node Proxmox cluster to be a 10GbE network card...

Iiay replied to the thread [SOLVED] Performance drop-off after upgrade from Proxmox v8.4.19 to v9.2.1.I did a "proxmox-boot-tool kernel pin 6.8.12-32-pve --next-boot" to boot the old kernel. The available and current clock sources end up the same, but with slightly different logging: dmesg | grep -E "clocksource|tsc|hpet" [ 0.000000] tsc...

powersupport replied to the thread Live VM Migration fails.Hi, The error client closed connection to the resume command means that the migration data actually transferred successfully, but the QEMU process on the target node crashed or terminated immediately when trying to resume the VM state. Since... -

Wwaltar reacted to hidigoudi's post in the thread io_uring on kernel 7.0.6-2-pve (PVE 9.2.3): guest disk I/O errors (EIO) + filesystem XFS shutdown with Like.
I can't reproduce the issue on kernel 7.0.14-2-pve. But nobody is able to determine what causes this problem.

OActually, I've been in the "real world" for 30+ years. And I never stated to not buy ANYTHING new, just be smart about it... Warranties and support contracts are huge money makers for manufacturers and it's cheaper to just buy a percentage of...

Kkrasiaa123 replied to the thread Proxmox VE 9.2-1 ISO not installing in nested Hyper-V.Ah, I see, that's the issue. It makes sense if it's caused by missing Hyper-V drivers. The question is, who should we report this to or address it with? Possibly raising a BugZilla issue...

For your information, your 4 wide RAIDZ1 offers 66.66% storage efficiency, while being very insecure. That is not that much better than a way better performing mirror at 50%. You won't see this problem directly in ZFS. You will notice that... -
I know it is pedantic, but in this specific case, there is no padding :) He/she is wasting storage because of pool geomerty. With 4 drives, we get a stripe 4 drives wide. Each stripe has three 4k data sectors (12k) and one 4k parity sector. For...

Lots do. I also always have to suggest this as well. If it were such a bad idea local-zfs wouldn't use it. I made a ticket in argument of changing the default if you care. I have a little snippet here which might be useful if you still need to...
