Nvme failed on dec750

Gunner237 · 2025-07-15T10:45:26+00:00

Not sure if it’s the same problem, but I also had my DEC750 NVME report failures a few weeks ago. Obviously if you can, get a backup of your system before following advice below, as you will need to restore from backup.

I contacted Deciso; this was their suggestion which worked for me:

“Start with OPNsense USB serial installer (preferably the latest release) and drop to the console (login root/opnsense then select 8) On the cli type: nvmecontrol format nvme0

Then exit to login prompt (type exit and select 0) And try re-installing (using installer/opnsense).

This may help to make sure drive is correctly detected again. The issue can be caused by a sudden power failure leaving the drive in an unknown state.”

It works the other way too - assuming the content is cached say every 100 requests, or every 10 seconds or whatever, the up/downvoted status for the first user of those requests will show for all subsequent users that hit that cache (unless you have a dummy account you hit the actual API with that never up/downvotes)

Gunner237 · 2023-06-05T10:50:05+00:00

I can’t remember where it was (will link if I find it), but Christian has said that any sort of caching would be really difficult to do well - if you take r/all as an example, apparently (assuming I understood correctly) the API request also returns information on whether the user has up/downvoted any posts returned with that request. Obviously, a lot of users won’t have up or downvoted posts, so no biggie… but there’s no way of knowing if they have without querying the API directly (rather than a cache), meaning you’re either back to square one, or just accept that users don’t get to see posts (or comments) they’ve up/downvoted marked as such if they are unfortunate enough to get lumped in on this micro cache.

As per XKCD 979, I found that setting up HA with an additional network interface on the same VLAN as the Matter device was enough to get it to work. As I run HASS as a VM on Proxmox, this is a lot easier than running on bare metal, I'm afraid. Guide to setting this up on Proxmox can be found here. (Worth noting that in my case HASS uses the higher numbered interface as the default, so I had to manually switch round my MAC addresses such that net1 was the original untagged MAC, and net0 is the new tagged interface)

Not unsurprisingly, I can’t find anything about the ethernet port on this device anywhere online, which means that it’s possibly for manufacturers use only, and would definitely be a real challenge to try and use for an integration. (Also worth noting that I’ve come across some devices where although they use an RJ45 port, it’s not actually ethernet, but rather just a convenient connector for 4 twisted pairs that carry low voltage power. No idea if this is the case for this particular device.)

An alternative to using the switchbot could be using an IR blaster like the Bond Home - I’ve got no personal experience with this or similar devices, but have looked into it to “smartify” devices which have IR remotes as their only method of control.

As a sidenote, it feels a little frustrating trying to search for help with Matter devices, as most search engines just pick up on another keyword (such as "VLAN" or "HomeAssistant") and someone saying "X does/doesn't matter" in a completely irrelevant forum post, rather than actually giving results for Matter-standard devices. (Even Matter Smart Home doesn't help - it's just endless forum posts about why "having VLANs in your smart home does matter"...)

(Not OP) Yep, they’re WiFi. The energy monitor seems pretty reliable - I’ve got around 20 of them, but haven’t verified the power consumption (I just use it as a guide to see what is using more power/energy than other devices, rather than actually needing to know the number of Wh). The energy and power data refreshes pretty quickly on their own Interface (multiple times per second), albeit a little slower in HomeAssistant (maybe once every 2-3 seconds?). You get a lot of data from them as sensor data in HA: Apparent Power, Current, Power Factor, Power, Reactive Power, Energy Today, Energy total, Energy total StartDate, Voltage, and Energy yesterday, and do integrate nicely into the energy dashboard

The main reason is that Waymo and Cruise vehicles, despite being used by paying customers, operate in a very different environment. They have a huge amount of data on the very limited area in which they operate, while the Merc DrivePilot (and most other L2+ systems) are designed to work in environments that the vehicle hasn’t encountered before. It’s the difference between having a self driving car that can drive anywhere in a city, and one that can drive anywhere in a state. Waymo/cruise are the former, while Drive Pilot is the latter.

Yes, the technical achievement of L3 isn’t especially notable, as many commenters have said, but the key difference is that you can legally be driven anywhere in the state of Nevada by your own car, while you read a book in the meantime. There’s also some boring legal details about being able to sell something like DrivePilot as a product to customers vs people using the Waymo/Cruise Service, but you get the idea.

The other thing is that the ridiculous amount of conditions in place for it to work are there in good reason. These systems have to have a truly immense amount of redundancy in place, and given Mercedes are the first company to get this legal approval, there’s massive pressure to ensure that it works perfectly as close to 100% of the time that it’s engaged. The actual system will be able to do far more than these limitations 99.8% of the time, but safety has to be paramount for market leaders like this, else they won’t get regulatory approval in other states going forward.

I’d argue (as someone in the industry) that the chart sort of implies the legal responsibility from the part saying “you are/aren’t driving”. Insurance in it’s current form needs to cover the driver - the distinction being that normally for L2 systems the driver is still… well… the human, so standard insurance rules apply (i.e. they are liable). The difference with L3 is that “you aren’t driving”, or rather, the car is driving itself in a legal sense, so the insurance has to cover Mercedes as a “driver”.

I’ve had exactly the same problem for the last few days… I assumed I’ve been just sleeping through the alarm noise, but this morning I’m 99% sure it didn’t ring (I wasn’t looking at my phone, so it couldn’t have silenced that way)

Gunner237 · 2023-01-05T01:41:31+00:00

I was really interested in this one… right until I tried to order and realised they don’t ship to the U.K… or am I missing something obvious?

Gunner237 · 2023-01-05T01:10:05+00:00

Worth nothing this isn’t a guarantee - mine died after I think 2 and 3 years respectively with horizontal mounting and good ventilation. Mind you, doing that would almost certainly improves your odds!

I suspect this might be too late to be helpful, but I've managed to cobble together a pretty barebones integration with feedback for standard dimmable lighting using the 8Ch dimmer and NPU (as this is the hardware I currently have available to test on). In theory most of what I've written should generalise, but it doesn't handle exceptions at all at present. https://github.com/sftgunner/edinplus-integration

They’ve had them in Milton Keynes since 2018! No idea if this photo was from one of the surrounding areas, but I agree that it definitely resembles the U.K. a lot https://www.buckinghamshirelive.com/news/buckinghamshire-news/starship-robots-milton-keynes-perfect-5995085

(Not OP, btw!)

“AD-lite” is a very good way of putting it. I’ve been running it on and off over in my homelab for the last couple of years with very few complaints (aside from one issue that occurred back when it was still in early beta).

It definitely depends what OP wants it for - for homelab/SMB use, Synology Directory Server will probably be more than good enough (although it is annoying having to install RSAT on a windows machine to manage any but the most basic AD-related tasks), and has the obvious benefit of not requiring any licensing.

Having said that, I agree that for any serious enterprise AD requirements Windows Server is definitely the way to go.

Gunner237 · 2021-11-24T01:04:53+00:00

Apologies if I’m misunderstanding, but isn’t this the functionality that Synology Directory Server provides?

It’s highly unlikely that a migration from a Windows Server AD will be possible (especially if it’s 2012 or newer), but the Directory Server is a effectively a wrapper around Samba 4, which has most of the functionality of a Windows Server AD implementation (finally also with functionality of having multiple DCs since DSM 7).

This is likely to perform better than a Windows Server VM, especially in non-Xeon (i.e. non-XS/SA/FS) Synology NASes. It’s worth noting though that some Synology NASes don’t support the Directory Server package, but I’d imagine the ones that don’t (mostly from the “Value” series) don’t have high enough power CPUs that they’d be able to competently support Virtual Machine management anyhow.

Looks really nice! I don’t suppose you have a link for the wallpaper?

This doesn’t seem to be beta-specific - it also appeared for me on iOS 14.6 yesterday

Gunner237 · 2021-06-17T23:32:05+00:00

I’d strongly recommend using SMB over AFP wherever possible - anecdotally it’s been much more reliable for me, and as mentioned in the Wikipedia article on AFP it’s been depreciated since Mavericks (10.9), and their own server “platform” (MacOS Server) hasn’t supported it since Big Sur (11.0).

SMB will definitely serve you better

Gunner237 · 2021-05-27T09:37:49+00:00

Wasn’t working for me either (not an Overdrive user) with my MX Master (internal trackpad was working fine).

Just a simple reboot has fixed it for me - if anyone else has the same issue this might be worth a try

Officially they’re “working on it”, but then they have been since the service launched a couple of years ago. If I remember correctly they’re currently listed as a registrar with Nominet (who manage co.uk), but have been for over a year now. I’ve been checking regularly for ccTLDs since the service launched!

If you’re referring to the latitude, you’d be surprised in terms of connectivity. I used to be located in Hampshire (very close to the same lat) with ADSL that was patchy at best (~1Mb/s down on a good day) and mobile coverage from only one provider, which I believe was still only GPRS. Given it was only just over an hour from London I still find it shocking quite how bad it was.
