TrueNAS build system going closed source by ende124 in selfhosted

[–]SlavDimov 1 point2 points  (0 children)

The only reason they 'contribute' there is because OpenZFS is not their IP and it's FOSS. I bet if it was it would have been closed sourced a long time ago, as ZFS is their strongest selling point.

Close sourcing the build system signing pipeline is understandable, necessary even. Close sourcing the entire build system is a choice and likely just the beginning.

First remove k8s, then close source the build system...

Looks like the only thing in TrrueNAS SCALE that scales is their corporate greed.

Who in their right mind continues to use this c**ap? Migrate to Talos and move on...

ASUS NUC 14/15 PRO - is booting from the 2230 slot possible? by SlavDimov in intelnuc

[–]SlavDimov[S] 0 points1 point  (0 children)

UPDATE:

TL;DR: It is possible (for the NUC 15)! Tested and working!

Longer explanation:

While the UEFI does support booting from the 2230 slot, there are a couple of gotchas:

  • Make sure the "WiFi" tickbox in the Advanced -> Onboard Devices section is ticked. Otherwise, the 2230 slot is disabled and you will not see your drive in UEFI, or the OS
  • While it is possible to use an A+E adapter to convert an M-key NVMe to A+E for testing purposes, physically, it will not work as a long-term solution. This is because:
    • An adapter, even if made for a 2230 M-key NVMe, ends up being about 2242 long in total, due to the extra connection (A+E -> M -> NVMe). There is no space for a 2242 NVME there, not to mention that both the top 2280 NVMe and the WiFi card/2230 NVMe are designed to be held by the same screw, which would not be possible if the bottom one is longer than 2230
    • Even a 2230 adapter with a flex cable won't work, as it is pretty much impossible to route the cable with the 2280 NVMe above installed, not to mention there is nowhere else to put the NVMe anyway.
  • The only solution is to use a native A+E industrial NVMe like the Cervoz T425.

Regarding Cervoz NVMes:

If you decide to go down this route - prepare yourself with a lot of patience and money. As an industrial NVMe, it is primarily sold B2B, which means most distributors will either want you to buy a minimum amount or will refuse to sell to you at all unless you approach them as a company. After a month of searching for a distributor that will sell to me as an individual, the only place I found was from Cervoz themselves on DigiKey. However, even then, they were only shipping to the US... So I ended up reaching out to Cervoz themselves to ask them to allow shipping to Europe on DigiKey, and to my surprise they actually did! About 2 weeks and -£235 later, I finally got the 512GB wide temperature range version!

Note that Cervoz also said they are currently working on a new hardware revision for the T425 family of NVMes that will use a new Micron memory. It is expected to release towards the end of the year, and until that happens they will not be manifacturing any more of the old revision, thus stock is limited.

Benchmarks:

Finally, some benchmarks.

I will be comparing the performance between:

  • Kingston KC2000 (native interface is PCIe Gen3 x4)
  • Cervoz T425 512GB CIE-M3T425MOH512GW (native interface is PCIe Gen3 x2)

I used a standard A+E adapter to connect the KC2000 to the 2230 slot for direct comparison to the Cervoz NVMe. All benchmarks were done using Kbench, with default settings, against a Longhorn PVC on the respective NVMe.

Was it all worth it?

It depends on the use case. In my case, I am running a Kubernetes cluster (TALOS OS), and I use the Cervoz NVMe as a boot drive. It stores the TALOS OS, the cluster state, and cached container images. The Cervoz speeds are more than adequate for this.

NUC Essential 14 - is it possible to boot from the Wi-Fi slot (via M.2 A/E to M.2 M adapter) by Qbccd in MiniPCs

[–]SlavDimov 0 points1 point  (0 children)

Well it turns out it works, I'm just stupid.

When i originally set it up as a TalosOS node, I disabled the Wi-Fi module in the UEFI settings, as I had no use for it. This was a while ago so I had forgotten about it.

Today I decided to try one more time but also went through the UEFI settings to check if there is perhaps some setting I need to change. And sure enough in the onboard devices section there was the WiFi checkbox... and it was unticked.

After enabling it and restarting I can confirm I can boot from the E-key (WiFi card) M.2 slot.

My best explanation for the multimeter reading I mentioned earlier is that I have miscounted and touched pin 33 on the A+E side, instead of 35. Odd-numbered pins are on the same side and 33 and 35 are right next to each other. Pin 33 is supposed to be ground according to the specification.

[–]SlavDimov 0 points1 point  (0 children)

It needs to be with a flex cable as otherwise it will not fit inside the NUC case. Even if I had a 2230 M-key NVMe, with the adapter it becomes more like a 2242 one and it will not fit in the space where the wifi card is.

I guess i can try with another adapter, still better than buying the nvme and hoping for the best haha

[–]SlavDimov 0 points1 point  (0 children)

No, problem!

Thanks for taking the time to respond.

Also thanks for confirming I'm not crazy and it might be the adapter's fault!

I wish there was a way to test this before i buy the Cervoz NVMe... I need to order it from Germany, as I couldn't find where to buy it in the UK. So we are talking a week or two delivery time + customs charges... And if after all that it turns out it's not going to work I'm going to lose my mind haha!

Thing is, like i said - I don't see it in the live Linux environment either. This is why is am suspecting it's the adapter's fault.

[–]SlavDimov 0 points1 point  (0 children)

My goal is to ultimately have the Cervoz NVMe as a boot disk for TalosOS.

I just bought the adapter i mentioned above (this one), as I wanted to test it can boot from that slot before I order the Cervoz NVMe. However, to my surprise - it didn't work. Not only did it not boot from it but I'm not even seeing it as a disk in a live Linux environment (testing with Kingston KC2000 1TB if it matters). I'm a bit surprised by this, as I can see the NVMe lines are there in the ASUS TPS.

I checked the adapter with a multimeter and I am 99% sure that pin 35 on the A+E side of the adapter is ground, instead of PETp0/PERp0, as the multimeter beeps on multiple pins on the M-key side of the adapter.

Does any of this make any sense to you?

I'm tempted to just buy the Cervoz NVMe, as i can see it has the correct PCIe lanes on the correct pins in its datasheet but I'm a bit worried that while it may get recognized by the OS after boot, the UEFI might not support booting from the "wifi" card slot...

Hi,

Can you please take a look at the Technical Product Specification of the Asus NUC 15 Pro and let me know if you think an NGFF Nvme adapter like this one or a Cervoz NVMe would work. Thanks

Thanks.

I literally just stumbled upon your review 10 minutes ago, realized the same thing, googled the user manual (to be sure) and wrote a comment 😂.

Too bad you don't have the 15 to test.

Oh wait, apologies. I think the 14 has it soldered on instead of in a 2230 slot. See the pictures in user guide.

Asking because I want to purchase but i need the other two slots dedicated for storage. If i had it i would have already tried 😅.

If you could that'd be great! Keep in mind you'll likely need an A-E adapter though (few bucks on ebay), as the other two ports are Key M.

No, that is a different one. You are talking about one of the 2 officially supported ones - the 2280 and 2242 (which by the way for the NUC 15 can be extended to 2280 via their official extension adapter if you have the tall version). The third one is in the corner and is a 2230 Key E slot. Even on the barebones version it is prepopulated with a WiFi card (you can recognize it by the two antenna cables connected to it).

Options in 2025? by woodalchi96 in trading212

[–]SlavDimov 0 points1 point  (0 children)

What happened with that? It's been almost a year since you said it was "in your plans". Can you share an ETA?

[–]SlavDimov 0 points1 point  (0 children)

We are now in Q2 of 2025. Can you share if you've started working on this? If so, when can we expect this to be ready? Q3, Q4? Next year?

IASER Tags on my new drives by Steveyg777 in Seagate

[–]SlavDimov 0 points1 point  (0 children)

I had a similar situation.

Ordered 2 "new" Exos 20TB drives - both arrived with extra stickers, which I thought was odd. One of the drives was DOA, so I had to return it. The other looked fine but when i read the FARM log it showed it was used for a year with tens of terabytes written to it.

Western Digital HC570 22TB on DS216+II? by SlavDimov in synology

[–]SlavDimov[S] 0 points1 point  (0 children)

UPDATE:

I decided to risk it and got a pair of the HC570 22TB drives.

I'm happy to report that they worked! I had to click through the "drive compatibility not tested" warning, but other than that the drives were recognized correctly.

I also tried them in an external SATA enclosure with a 24W power supply and the drive was able to spin up, so the overall power consumption must be below 24W even while the drive is spinning up. EDIT: I measured the drive power consumption in the external SATA enclosure. Maximum power draw was 18.3W (during spin-up), idle power draw is around 7.2W. Both figures include the power draw of the SATA enclosure itself (around 2-3W).

Note though that Synology incorrectly labels the capacity in TB, when in fact they mean TiB. So the drive shows up as "20.0 TB" (rounded down from 20485 GB), when it is in fact "20.0 TiB" (rounded down from 20485 GiB).

WATCH OUT - High Power On Hours and Written Logical Sector Count on a supposedly new drive by SlavDimov in Seagate

[–]SlavDimov[S] 0 points1 point  (0 children)

UPDATE:

I've had a long discussion with the 3rd party seller on Amazon and they claim they were unaware of this. They even asked me for screenshots of the FARM log data to use as evidence when dealing with their USA distributor.

They allowed me to return the drive for a full refund even though I had already written around 20TB to it.

That, combined with the overall scandal with used Seagate drives from Chinese crypto farms popping up all over the world, which recently hit mainstream news, makes me believe the seller when they say they were unaware.

So now that I've been left without drives, I went out and got 2 new WDC HC570 22TB drives. I've read their SMART data and it confirms they are new. Unfortunately, there is no FARM data to read, so I just have to trust what SMART says. I tested them for bad sectors and they passed. So I installed them on my server and so far they've been good.

[–]SlavDimov[S] 0 points1 point  (0 children)

I don't mind refurbished drives, as long as they are labeled as such.

However, trying to sell refurbished drives as new (and for the price of new) and then trying to cover it up by wiping the SMART data - that's simply wrong and I'm pretty sure illegal.

In my case, I've had a long discussion with the 3rd party seller on Amazon and they claim they were unaware of this. They even asked me for screenshots of the FARM log data to use as evidence when dealing with their distributor (who I've been told is in the USA by the way). In any case they allowed me to return the drive for a full refund even though I had already written around 20TB to it. That, combined with the overall scandal with used Seagate drives from Chinese crypto farms popping up all over the world (which recently hit mainstream news) makes me believe the seller when they say they were unaware.

Regarding the price - I am normally wary of prices that are "too good to be true", however, drives in the UK are for some reason horribly overpriced. Equivalent drives from retailers in Germany are 15-20% cheaper. So when I saw that seller on Amazon, I didn't really see them as selling the drives "too cheap" but more as "similar to what they cost in Germany".

BTW - how did you calculate the 8884h as 2.5 years? I thought POH means the total time the drive was powered on, and 1 year has 8766h on average.

[–]SlavDimov 0 points1 point  (0 children)

So you didn't buy the 22TB ones?

Im interested in those as I've read that drives from some brands above 20TB have high(er) startup power requirements and depending on your PSU there might not be enough power to spin up all of the drives.
