Thanks for the pointers. Bug 7558 looks related but I don't think it's the same failure. Two corrections and some new data.
Update — 5th occurrence, now with a full trace and the blocked task's stack
Correction on my setup: my NFS mount is not...
Hi @RealSoulskater
thanks for posting on the forum!
I can confirm this also happens on my test PBS.
Will look into the code since this also doesn't make sense to me.
Best regards

Thanks, this was very useful.
I have now captured another NOP timeout with both the rolling PCAP and an extended 1-second host-side logger, and some of your questions can now be answered more precisely.
The advertised Linux TCP receive window...
Sorry if I send you my current cluster, what I should make and on another location where I have my laboratory. With this configuration you see there are several lxc VM machines and all in NFS on a small nas g1 of the hp with xigmanas and a...
PVE 9 ships ZFS 2.4 (since january 2026) - and with the update from ZFS 2.3 -> 2.4 the library-packages got a soname bump (libzpool6 -> libzpool7, libzfs6 -> libzfs7).
As both versions of the library can co-exist on a system (in case any old...
Virtual machine support is better classified first by CPU architecture rather than by the guest OS itself. At this point, the relevant architectures are x86 and ARM.
The next question is whether the guest OS supports the virtual hardware...
I don't experience this and it's the first time I hear about significant overhead or even stalls due to that.
Stall is a bit too vague to suggest much but maybe perf top --sort pid,dso,symbol can reveal something.
As Impact said, if you have an issue, that really completely stalls a Quad-Core CoffeeLake CPU, then this (Intel Ethernet issue originally discussed here) is most likely not the issue, that you are experiencing. Just because you have one of the...
No, I haven't see news on this in this decade.
The technology behind this is named COLO (COarse-graned LOck-stepping) and i documented here. Feel free to ask in QEMUs socials about it. PVE will have it if it is available.
Until then, just go...
That will work yes, as for capacity for how many VMs it can handle, this is down to what VMs you plan to run. You could see how far you get with 16gb of memory and upgrade as needed.
Coming from VMware, we would love to see fault tolerance for zero/minimal downtime too. After talking to other sysadmins, that's one of the features still a roadblock for them.
Moving the config file doesn't stop the VM; nothing watches /etc/pve and kills a running kvm process when its config moves away. All you've changed is which node PVE thinks owns the guest, so the process on vm1 carries on running and writing to...
After ten years I'm very surprised this hasn't come into standard deployment.
The app level clustering is fine but the block storage handled by the host is a challenge.
Shame.
Did you make any progress on this ?
I'm thinking of trying the same. I will be using lxc, not VM.
Not sure if my equipment is compatible. I have a Roland UM-880, Fantom XR and VK-88. All ancient.
Yeah the container has failback disabled, this seems to be the reason why the container can be moved to a different host, even though the other host has a lower priority.
Is object lock support on the PBS roadmap? All it has to do is keep a catalog of active chunks and renew their locks on a regular basis.
This is a major pain point for us and is keeping us on Veeam instead of PBS. It's not a "nice to have...
Hi
I'm currently running a dashboard called Homepage where i have a widget that checks for disk space and failed Tasks 24h back.
It calls the API like this where since is set dynamically to check 24H back...
