Are SSD NVMe issues resurfacing with the latest PVE kernel upgrade?

I'm not sure you are justified in commenting on kernel stability with drives, when in your case, it is probably down to the interfacing you are doing, and not the drives themselves vs the kernel.

well E3, U2, M2 they are all connecting via NVMe over PCIe, it is just a different "plug", in fact most of the time the SSD use the same controller chip regardless of form factor.

and you are correct this system has no M2 slots

the SSDs are fittet via a passive pcie/m2 adapter.

system has even only PCIe v3 and one of the SSD has even only one PCIe lane attached.

but even so they are miles faster (latency!) and cheeper then attaching enterprise sata SSD's as special device ;)

anyway i had the same symtoms as other people here, just wanted to throw in another data point that it also happens on different hardware and non ceph related usecase.

What are you running on that dual-core calculator?

mostly PBS sync target and a little PVE for homelab thinkering.
the calculator is 99% idle and still uses to much power for what it does :)

The problem with the converter from PCIe -> M2 is that the adapters themselves are relatively dodgy. And then if you use a cheap drive on top of that with a system that’s so old some of the caps are probably bulging…

As far as the difference between PCIe, M2 and U2, it’s a bit more than signaling, there is the issue of power, latency, bandwidth, hot plugging, namespaces, security concerns with VFIO (in some setups) and whether or not your system supports it as a boot target.

If you’re concerned about power usage, a newer system, even a low cost used one is going to be much more reliable and efficient than that model, depending on where you live you may save the money just on the power bill. I went from a Nehalem for my home lab to CascadeLake and the power usage dropped during idle from ~100W to 50W or even below that, just because the entire system is so much more efficient. I don’t really care about that at 4c/kWh, but you may, even at my cost, I will ‘save’ money for the next system in just a few years.

Although this is rather off-topic, if you really care about power consumption (which you should, these days .....), you should deploy a mini pc in a home environment to run essentials etc. 24/7, & you won't hit 20w idle. I'm at ~13w with 3/4 VMs & 4/5 LXCs.

Just my off-topic (reply) 2 cent rant ....
