Since 14.4 beta 4: all SSDs "show up and stay" (no raid, two PCIe cards with one SSD per card)
Oh I hope that your experience and mine is the end of this error. Fingers crossed.

I have one Sonnet card with two NVME, not in raid.
 
Problem is back after some days. After two restarts the SSDs (see #176) are mounted.

Not just you, but anyone who's having this issue - how about setting your machines to boot in verbose mode, and seeing if anything unusual comes up during the boot process?

Bah! Damn... :( Mine is still behaving so far, the drives are both staying mounted.

I see 14.4 beta 5 is out now, haven't installed yet.

I can try to see if verbose mode gives anything.

Can assure you. We all appreciate your efforts.
 
Well what is strange is that I'm not getting these crashes anymore.

One of the NVME drives runs windows 11 pro for workstation, the other is just a storage drive. So it's odd - I did get these crashes but still with 14.4b4 it is still fine.

Previously these crashes would happen frequently but not at all, I used to do absolutely nothing and this would occur. Now it is fine.

Sounds like they're heading in the right direction at least.
 
Same here, I'm so disappointed.
I'm considering to abandon MacOS and switch to Windows 11.
The stability, cpu and gpu performance is so much better under the Win11.
Microsoft also updated the UI and it is on par with MacOS now IMO.
The drivers are regularly updated, not like apple abusive strategy to just ditch the MacIntel users.
They sold MP7.1 in 2023 so there should be bug fixes and new amd drivers for pro users for many years.

I refuse to buy MacStudio, the next workstation will be PC under Win11 sadly.
In MacStudio everything is soldered and can't be upgraded and MP8.1 just doesn't make any sense...
I understand this approach for portable devices but for workstations?
God damn it Apple... they've become so aggressive and so greedy, beyond imagination...
I won’t even start about the right to repair…

don't know why you guys didn't see the writing on the wall a while ago.

lol abusive strategy. APPUL is eventually reverting back to its PPC era, which if you ask the homers like g5isalive, "was PEAK APPUL" because this is how they've always been.

i'm over it. i've found such a massive issue with dual processor systems using max memory with MATLAB's parallel computing toolbox, that i know if i had the same specs in windows it wouldn't be devouring ram the way it is.

intel's dev team opened my eyes about this issue ten years ago, which i acknowledge applies strictly to dual processor configurations, but is a problem nonetheless. tsialex's followup about NUMA architecture all but confirmed these limitations.

i am excited to move back to windows. i think what they've done with powershell+WSL will probably make me forget about mac altogether. although i will definitely miss the 'insert pattern' option for finding and replacing text.

i'll be laughing in ten years when people like senttoschool and g5isalive will be clutching their stock, pathologically championing APPUL's flawless execution, while i fondly reminisce my early years "exploring" windows, finding hover, and **** like that. it's probably a better story.

my mp5,1 did what sir tim's did anyways. it'll be retired eventually so i think i've paid tribute to the greats enough.

**** APPUL.
 
Hey guys,

I am havining an inconsistant issue with both my NVME drive adapters intermittingly failing to mount on my 2019 Mac Pro on Monterey 12.6. I'm constantly having to restart the machine to get the drives to mount. No drive issues or fails via Disk Utility and just gives 'Invalid Disk' error when I try and mount manually. I've also just sent back the Sonnet Flex J3i back for a replacement as the Raid setup was failing on each restart via the USB connnected SSD so not sure if this is a related issue. Also worth mentioning that I've recently replaced the MPX module with 2x RX 6900 XTs.

1x Sonnet’s M.2 4x4 PCIe card
- 4x Samsung 980 Pro 2TB (8TB HFS+ Raid0)

1x OWC Accelsior 4M2 PCIe card
- 4x Sabrent 1TB (3TB HFS+ Raid0 & 1TB Windows)

It's worth mentioning that the 1TB Windows SSD always mounts and the issue is just with the 3TB & 8TB RAID drives.

My system report is attached in case there's anything in there that could help.

Thanks in advance for any advice that you may have!
Hi again Luke, you have the same sonnet drive carrier that I do, had my first mounting issue today.
Starngely enough I never have a problem with the Windows drive either.


Just to check, is there anybody that is having this issue not running Windows from an NVME also?
 
I made the mistake of upgrading to Sonoma recently and I’m starting to regret it.

I also encountered this issue last week. My HighPoint Raid card was displaying that in slot 1 there was no detected drive. I thought it was weird that the nvme failed but tossed it up to bad luck. I bought a new nvme drive replaced it and booted up. Everything registered and I recreated my array and restored my data. Two days later after a reboot I see the same thing. At this point, I know it’s not hardware failure.

I found this thread and tried resetting PRAM and upon boot the drive showed up again as if nothing had happened. I haven’t rebooted since but I assume that my drive will disappear eventually as others have reported.

I opened a case with the vendor and reported this issue so they can report to Apple. I supplied log files, specs, screenshots and asked if they had any permanent fixes for the issue. Haven’t heard back yet.

I’m running latest version of Sonoma. With a HighPoint SSD7101 Raid card. I have had this card installed for as long as I have owned the Mac Pro since release in 2019. Have the latest drivers. I’m using Samsung 970 Evo + nvme drives. This config has been rock solid and I never had an issue until now.
 
FWIW, the problem has stopped for me & since updating to the latest Sonoma 14.3.1 - others report here that this is not the case for them, but so far I've cold rebooted at least 12-15 times now & the Sonnett 4xM2 is still good (does seem a little slower to mount though). Otherwise, everyone seems to agree that 14.4 fixes it for sure.

Yep. Have worked with MacOS, Windows and Linux in large scale university deployments for some 30 years now. My short take is that in the last decade & following the passing of Steve Jobs, Apple has become overpriced consumer rubbish -especially revevant for their so-called 'pro' market & which they've also screwed (a 'pro' phone? please ....)

Their support is hopelss & clueless & clearly their strategy is to wear you down and make you go away. Seriously, try and get any sophisticed mac pro support. They have zero idea. Try taking it to an Apple store and so-called 'genius' bar, again, hopeless +having to be in a crowd of nitwits with a hand & eyes permanently glued to an overpriced phone.

Then there's the dumbing down of tying to configure or cusomise annything, eg: having to sit with a finger on the option key or C-R keys for a couple of mintues wondering if its actually doing anything; Win allows one tap, then select from menu. Ditto terminal commands are consistent forever on Win but Apple continues to change them every OS update. Dreadful. Then the OS itself - every update usually brakes some 3rd party pro apps,plugs,drivers,VIs etc. PITA. sfc /scannow anyone? I wish.

Yes to Win 11, but one needs to understand computing a bit more; Apple's walled garden tries very hard to ensure one cannot easily do that & increasingly dumbs people down & makes it hard to escape from the 'magical' products.

Only one winge I have about Win 11 for pro audio in particular: the drivers can be odd & is worth sticking with excellent outboard (German RME for example), plus, there is no useful equivalent for Apple's Aggregate Audio (though again, Sonoma has broken a little of that for when running muliple audio devices).

Depends entirely on your use and expections, but the 'pro' Apple has gone.

Pro Apple has not gone, but its has become MUCH more sloppy. When you dissasemble MP2019 - the quality of design is still there, but software....I can't believe that after so many Sonoma releases they cannot solve this issue. If they cannot fix it - its bad for all of us MP users. But if they don't care, its bad for all Apple users.

Hi guys,

Same problem here with a MP 2019 and an OWC Excelsior PCie card (4 SSD in raid 0)

I tried using SoftRaid, changing the slot, reinstalling Sonoma, rebuilding the RAID... this random error of disks not mounting keeps occurring.

I need to check if the Sonoma beta version will change anything, and also use JBOD instead of RAID, or downgrading to Ventura.

Actually we don't hear much from Luke, who seemed to have solved the problem by using softraid (thanks but I just spent 50$ for nothing)
 
iOS 17.4 is out, but Sonoma 14.4 is still RC. Let's see if something will change.

I tried anyway to write to Sonnet, here is the answer:

Thank you for the information. We are sorry that the M.2 4x4 is not working for you.

We are aware that other customers are having the same issues.

Our engineers have been working hard on this and have now been able to reproduce the issue. Just recently we were able to duplicate this issue with competitor's hardware. From the data we have gathered from other customers, and in our lab, it seems that an update released by Apple in the 2023 time frame for multiple OS releases caused the issue with drives dropping off. We are trying to narrow down exactly which ones.
We have filed a bug report to Apple so that they can get the issue fixed in a future OS release. We are sorry for the inconvenience and are working hard to get it resolved as quickly as possible. We have your case status listed as Waiting for Engineering Fix so that we can alert you once there is a solution.

As a workaround in the interim, removing and installing the card/drives into an external Thunderbolt to PCIe chassis like our Breakaway Box, seems to provide access to the drives, albeit, at Thunderbolt 3 bandwidth of ~2750MB/s.

Let us know if any of this helps.
 
Thanks nopster !

I will not spend another dollar and wait for the fix. It's really disappointing to have spent several thousand dollars and having trouble. Instead of working on an amazing professional machine, I am trying to fix issues as I was using an old and creepy computer. And I loose money in the meantime, not doing my usual job.

Me too! Why I have to buy another external box! I switched from OWC Thunderbolt box to Sonnet card to have drives inside Mac Pro. Why I have to use it again?
 
Just an FYI for everybody regarding the Apple internal SSD. Even if it's not on the store actually in your country, all is not necessarily lost.
I asked the Q here in the UK;

For arguments sake if your drive did fail in your Mac yes we can currently get the parts and repair your machine so you have no worries there.
The only thing I can think of is that the support advisor was referring to not being able to get the user upgradable kit from apple.com, not an in store service.
When going through this with the in store department we can certainly see the 2TB kit as an option to order.
If they can then order this you would need to drop the Mac off to the store and leave it with the technicians.
They have also confirmed that they would need to install the OS as the Mac would need to pass some tests before we hand it back and mark the upgrade as successful
.

I'll let you all know if it is order able and the cost.
 
yeah but we are not talking about the Apple Internal SSD. The PCIe card is made to avoid buying expensive apple SSD's while keeping a lot of options regarding the capacities, raid setups, backups, possible upgrades.

The whole machine has been designed to welcome pcie cards such as those. If it's to end up with a single large internal SSD, I would have chosen a mac mini and probably saved 4.000$

Man, Apple and OWC have sold me the supposedly best stuff on the market, and all was supposed to be fully compatible. If I have to spend money to fix their mistakes, I don't call it the best stuff, I call it the best scam ever !

After 2 reboots the beta 14.4 seems ok, but for how long ? Logic X seems to freeze a bit more than usual... I hope they will solve this in the following weeks !

Yes, I know that.
I just thought it would be useful info as without the internal, none of the externals will work.
 
For those of us who still can't depend on the OS to do the job, is fully disconnecting the computer from the power between boots (i.e a SMC reset, as I understand it) a reliable workaround, as far as we know? If not, what about a PRAM reset?
I'm just catching up with you after hitting this problem with my Mac Pro 2019, running two Crucial P5 2TB drives on 1M2 cards in slots 6 and 7 (Sonoma 14.3.1). Most of the time they both show up, but a couple of times they've both gone AWOL - the first time when coming back out of sleep mode, I think (so I've disabled that) but the second time after a shutdown and reboot without having disconnected the power in between.
Has anyone tried using the expansion slot utility to assign their M2 cards to a specific "pool", to see if that helps with their recognition/initialisation during the boot sequence? I turned up this article about a different problem with the 4M2 card, to which that was a suggested solution. In my case my 1M2 cards are automatically being assigned to pool A, so I'm a bit reticent about moving them to B! I wonder if simply disabling automatic bandwidth configuration might help in itself though too, so am trying that first.

Great, thank you for testing this aventham ! keep us posted about those possible solutions, even if I suppose the techs from apple and OWC have tried already...

So far the beta version 14.4 is working, but I just made a couple of reboots today...
