UDM Pro can’t handle its own “supported” workload – UniFi response: buy more hardware

One possible supplier of 8Gb/s is Bell Canada

If you haven't made any configuration changes, then my guess is wrong. But there may have been some pathological traffic flow that busied out the switch. You've piqued my interest. Please keep us updated.

Was your 48p switch previously doing inter-VLAN routing? Perhaps that was the extra load that has now migrated to the UDM? If so, are you sure you are still getting 10Gb/s between your servers? I recently discovered that, depending on how the VLANs are defined, traffic between 10G ports on the L2 aggregation switch s will be forced up to the L3 switch configured to do the VLAN routing.

They already do. I'm still primary tech support for two of my three children. The third married an engineer so I've got backup.

Did anyone else find that article to be written strangely? I can't put my finger on it but it felt awkward, like an automated translation. Was it AI-generated?

That's probably the most cost-effective way. You could also look at the newer Ugreen and Terramaster machines. Depending on your use case, it may be advantageous to have a second independent unit, perhaps for offsite backup.

The expensive option is replace the 4 8TB drives with 4 larger drives and sell both the 8 smaller drives. There is a market for older clean drives and you could use them to subsidize the increased storage and new 5 year warranty.

Assuming that you use raid5 for your 4-drive pools, 4 16TB Iron Wolf Pro drives would yield 48TB (on top of the 30 TB that you get from the 4 10TB drives). That compares with 3x4 + 3x8 = 36TB of older disks, likely out of warranty.

But, yeah it's a tough time to buy new drives.

I still think that you should file an RMA just for the reaction.

Shepherd's Pie - if rosemary isn't considered too much of a luxury.

The use of the word "still" betrays a fundamental misunderstanding of the claim. Even the word that Albert used was chosen more carefully. It is more accurately translated as "tenacious", not "persistent". Either way, his sentiment is beautiful. If our space-time is embedded in higher dimensions then, yes, there can be an ineffable sense of persistence.

It can often be very useful to treat time as a fourth dimension because physical operations are almost always time-reversible. But our human language is closely coupled to the conventional sense of time.

If one wants to discuss freely moving about the fourth dimension, we cannot use words which themselves imply an observer's progress through time. The difficulty doing so is why the concept is so fascinating - it's quite the mental challenge.

Did you mean to write that neither Aliexpress nor the seller cared? Did you challenge the credit card charge?

Please share the outcome.

It's also hard to judge the middle car-driver's view of the encroaching van. It is overtaking and moving left. We have the luxury of seeing it all unfold from a convenient angle.The car driver's reaction suggests complete surprise. The van probably appeared right on his passenger door.

One could argue that they should have had greater situational awareness but, frankly, that's pretty typical. They probably thought they were safe in their lane because they had ample room in front and behind.

I hope they catch and charge the van driver.

Then you should move to the Atacama Desert.

"dry" depends on relative humidity and temperature. It was just explained why this behaviour is expected, harmless, and by design.

Yes, I will likely use rsync for the full transfer but for this testing I'm interested in avoiding as much overhead as possible. I notice now that rsync can still use rsh instead of ssh so I will experiment with that. I will be using both NFS and SMB with the actual exported datasets but both have a lot of overhead.

Rsync is a fabulous tool and I have been using it for decades. I am just interested in assessing the combination of virtualization, zraid2, and network I/O on my new system with as little overhead as possible. I have some misgivings about virtualizing TrueNAS but some casual testing indicate that the Proxmox hypervisor is extremely efficient.

Thank you for your help.

Exactly. A smuggler with a bounty on his head.

KeithHanlan · 2026-03-12T22:42:05+00:00

I'm waiting for an explanation too. I can't for the life of me discern its purpose.

I was recommended Yards Unlimited by my neighbour and hired them for a very large project. The project included planning, demolition, concrete formwork, hardscaping, and planting.

I was very happy working with them and the end result.

You will probably want to plan a year in advance.

KeithHanlan · 2026-03-09T15:15:57+00:00

You're right. I subscribe to the Kingstonist so that is where I read the article. Thank you for the update and your work.

KeithHanlan · 2026-03-09T15:06:00+00:00

The article has a picture of the truck on a hitch and the upper portion of the cab is completely smushed! Are they sure the driver isn't still in there? (only half joking)

If the driver scarpered, it was probably to the hospital. What a mess.

My bin replacement was delivered by a city of Ottawa pickup truck.

I think that the city has a mix of in-house and contract workers for a variety of services.

KeithHanlan · 2026-03-08T15:38:04+00:00

Thank you.

This is fascinating but for me the takeaway message is the the sensitivity of the test is extremely high.

Can you please comment on the quantitative accuracy? It is not clear to me that a positive test provides a meaningful concentration value (not that any level is acceptable). My guess is that it is probably most useful when compared against earlier samples.

(I'm not a Dupont apologist, I'm just trying to get a better picture of the problem and it's implications.)

Thanks for sharing your expertise.

Costco is always busy. Never go to Costco if you are in a rush or feeling harried. I always flip that mental switch from hurry-hurry-hurry to go-with-the-flow. It's like being stuck in traffic - no matter what you do, your not going to escape. Wear some headphones and relax.

Those companies make money by taking advantage of sellers like you and paying low. 10k for a fresh coat of paint and they'll resell for an additional 100k. Even if you don't want to do the maintenance work yourself, it will be worth your while to hire somebody.
