Ok, so: There's definitively something odd with the block layer statistics for phyiscal devices in these kernel versions (7.0.14-8 now). In my log, I see sudden large jumps in write ticks and time_in_queue values, like in this example (leading... -

Wweppa replied to the thread Opt-in Linux 7.0 Kernel for Proxmox VE 9 available.This creates spikes that are well above munin defaults for sending emails. And these defaults are set by munin maintainers ? It's 0:3 by default (warning/email if above 3 seconds). It's like that since 20 years I believe... WARNINGs: Write IO...

Wweppa replied to the thread Opt-in Linux 7.0 Kernel for Proxmox VE 9 available.If this ever gets to a kernel developer : this is super easy to replicate ; just add munin package on a vm or LXC, or even on the host itself. monitoring disk latency is default. pve devs say for -6 update submodules and patches to...

Wweppa replied to the thread Opt-in Linux 7.0 Kernel for Proxmox VE 9 available.I'm back at -5 and the problem vanished . So basically the problem appeared in -6 (as per Galaxis) , is still there in -8, I was just a bit late in the game. If it's a new kernel feature and not the sign of the disks getting crazy, it sure...

It's basically unusable (I've got 440 emil alerts this morning) and very...

Wweppa replied to the thread Increased latency on disks since 9.2.6 and associated 7.0.x kernel.Thanks @Neobin ! In the meantime proxmox-boot-tool kernel pin 7.0.14-5-pve proxmox-boot-tool refresh UPDATE : I can confirm the problem DISAPPEARS with kernel 7.0.14-5 So it's specific to kernels after this one.

Wweppa posted the thread Increased latency on disks since 9.2.6 and associated 7.0.x kernel in Proxmox VE: Installation and configuration.I have a couple of proxmox VE hosts, running 9.2.4 with 7.0 kernel. These systems are updated regularly (like once a month) with proper reboot For the last update (9.2.4 to 9.2.6 - on the 7.0 kernel) I have something weird happening that trigger...
