Ddjsami replied to the thread Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository.I fully understand and accept your point regarding the repository hierarchy. You are right; relying on the test-repo for a production environment of this scale was a risk that ultimately fell on me, regardless of how stable it had been over the...

Ddjsami replied to the thread Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository.Let’s be clear: I have been managing this 1,200+ node infrastructure for over 2 years using this exact same repository structure without a single critical regression—until now. While you point out it's a "test" repo, in a professional...

Ddjsami replied to the thread Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository.I am writing this to express my deep frustration regarding the pve-qemu-kvm 10.2.1-1 update. I manage a massive infrastructure of over 1,200 nodes, and this untested update has caused significant distress across my entire operation. I have spent...

(Patches in the test repository.I've been using the test for two years and this is the first time something like this has happened to me. I will be downgrading this other cluster structure after 4:00 AM.

Inneresting! I did not have that occur on mine. For sure the proxmox team will identify the reason why - lets remember this is a package published to test so those of us brave enough to use that will know the caveats. I reckon you might want to... -

(Patches in the test repository.pve-qemu-kvm 10.2.1-1 pve-qemu-kvm 10.1.2-7 There's a difference of more than 25%. Not only IOPS but also CPU and, naturally, RAM usage has decreased.

Excellent! Thing is, as alluded to previously, I dont actually think its increased io. I'm not the worlds best at iotop but I wasnt seeing any difference - only in the realtime bar i/o delay and the io pressure stall graph. Good luck hunting...

Ddjsami replied to the thread Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository.Quick update: I have just downgraded pve-qemu-kvm from 10.2.1-1 to 10.1.2-7 on my nodes, and I can confirm that all IO Delay and IO Pressure issues have completely disappeared. Before the downgrade, I was seeing a constant 20-25% IO Delay even...

Ddjsami replied to the thread Applying pve-qemu-kvm 10.2.1-1 may cause extremely high “I/O Delay” and extremely high “I/O pressure stalls”. (Patches in the test repository.Glad to hear you can reproduce it. To provide more data: I have tested this across my entire rack of servers (multiple nodes), and the result is identical on every single one. They are all experiencing the same ~20-25% IO Delay since the 10.2.1-1...

I can reproduce the issue locally and will look into it.

Ddjsami replied to the thread Ceph - VM with high IO wait.I'm experiencing the same thing. There's something strange going on with Proxmox 9.1.1, and for some reason, my IOPS jumps to 500%. I haven't found a solution. The actual disk is fast, but slower than Proxmox :D I think there's something...
