This is weird. What version of PVE are you using? And did you mangle with your (global) bash configuration?

It is almost 3 years now that I posted my "solution" and things have evolved a lot, since. QEMU and the linux kernel have received numerous updates, that also affect nested virtualization. Because of both performance and stability issues, we've since completely gotten rid of all Windows VMs...

HI, I need to replace a switch in one of our datacenters, that is used by a couple of PVE nodes for almost anything (corosync, ZFS over iSCSI, node to node traffic for VMs etc.). The replacement shouldn't take long, but still it may take a minute or so. For all the traffic except ZFS over...

there's actually an simple workaround for this. Say for example if your boot device that is NOT attached to the HP P420i is sda and your HP P420i devices only start at sdd, then just modify char_index from. old: char_index=({a..p}) to new char_index=({d..s}) That way, the wrapper script won't...

Thanks, but I highly doubt this has got anything to do with my issue. I'm talking about a linux guest (debian buster) running it's own kernel and I can't imagine the PV host kernel would interfere with the device renaming in a guest VM.

I've recently upgraded one of our installations from 6.x to the latest 7.x. Because of that I have been monitoring the VMs a little bit more closely, which is why I noticed one linux VM behaving strangely. This is a debian 10 VM with more than 10 NICs and after closer inspection, I saw that a...

I'm "suffering" from the same situation, with a P420i controller in RAID mode. The UI would only show an error when trying to access the SMART values via the "Disks" page. So what I did was to write a little wrapper script around smartctl, adding the "-d cciss,X" as needed. /dev/sda will get...

Yes, there are some windows VMs running on that server, but I haven never seen those messages before for a windows VM. The only "special" thing on this server is a MacOS VM, so I guess that's where the noise is coming from.

reviving this old thread, just to check if the messages I am seeing have the same origin. After a recent update to the most up2date 6.4 version, I keep getting a lot of messages like the ones below in the journal: Sep 15 10:46:11 concordia kernel: kvm [11085]: vcpu3, guest rIP...

It was the power supply failing. While the server is not even close to high load, occasional spikes were enough to trigger the failure.

I'm trying to figure out how to have a cluster wide startup order. Initially I thought, the "Start and Shutdown Order" mentioned in "11.3.6. Automatic Start and Shutdown of Containers" of the PVE Admin guide was the way to go, but it turned out that this "Startup Order" is only taken into...

final update: this has all turned out to be completely non-proxmox related. Instead my nice little home server has died ungracefully from a hardware failure ... Sorry for the noise :)

it has just happened 5 times within shortest time, and in total 8 times this day ... Dec 13 11:00:58 foundation kernel: Command line: BOOT_IMAGE=/vmlinuz-5.4.78-2-pve root=UUID=6ad2877d-c58a-4337-8968-b432410fb376 ro quiet intel_iommu=on Dec 13 11:00:58 foundation kernel: Linux version...

I only learned today that my home proxmox server reboots frequently. Sometimes it's sufficient to just start it to have the proxmox server go down an reboot. Unfortunately, I only activated the journal today, so I can't say how long this has been happening. After activating persistent logging...

Thx. What I am interested in is the "written to disk out of order and asynchronously" part. Obviously, at a certain point of time, the pending data must be written, no matter if a guest's flush command gets ignored or not, for example if the cache is full or once the VM terminates. Which...

Like the title says, I am trying to understand the implications of using cache=unsafe for some VMs. Don't you worry, I did my homework and I am well aware about what the PVE documentation says about it (ie https://pve.proxmox.com/wiki/Performance_Tweaks), as well as numerous other sources (eg...

it runs on the original HP firmware in IT mode, nothing fancy here :) But as we use those controllers in a a couple of servers, I noticed that the controller in question has a slightly outdated firmware. I'll update to the latest firmware version coming from HP and report back, if that changes...

yes, that's what I am using. The proxmox node is serving iSCSI requests using LIO, and to be even more precise, we're talking about ZFS over iSCSI.

We're using one of our proxmox nodes as an iSCSI target. The node is equiped with an HP H220/LSI SAS2308 SCSI controller with a number of disks attached to it. During high load (particularly when cloning or when the backups run), the kernel ring buffer get's spammed with tons of "Unsupported...
