MP 7,1 Mac Pro 2019 NVME RAID drives failing to mount

LukeMacPro said:
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!

Chiming in with I think the same problem. I do music production and am slow to upgrade my OS. I wait until I am between projects and make sure all my music hardware and software is compatible. I upgraded from OS 12 to OS 14.7 Sonoma and omg where are my drives.

I use the internal 8TB OWC Accelsior 4M2 PCIe 3.0 M.2 NVMe SSDs

They've worked beautifully until the upgrade. I restarted and phew there they are but it's happened 3 times and I'm freaked out, worried the next time might be permanent. I've made 3 separate backups (2 physical and 1 cloud) just in case.

Reading through this thread it sounds like the solution is: use softraid?

MacPro (2019) 2.7 GHz 24-Core Intel Xeon W
OS 14.7

No, softraid won't change anything. The only solution is to downgrade to Monterey or upgrade to Sequoia.

I just got a reply from OWC:

"
Thank you for sending the SoftRAID report. I spent some time reviewing it and there is one thing that jumps out at me immediately. I see that you are currently running macOS Sonoma 14.7. macOS Sonoma had some bugs in it specific to NVMe drives connected to a Mac Pro via a PCI card. We published our findings and suggest that all Accelsior card owners upgrade to macOS Sequoia to resolve these issues. If you'd like to check out our article, https://eshop.macsales.com/blog/96475-upgrade-macos-15-sequoia-softraid-8-3.
"

Looks like I'm a little stuck since most of the makers of all my audio software recommend waiting to upgrade.

Sonoma is really unusable with MacPro7,1 PCIe drives, Ventura is better related to this specific issue, but worse with others. Maybe Ventura works for you.
 
^^^^My NcMP 7,1 has Ten internal SSDs. Six are on Two PCI cards. I have had no issues mounting any of my drives with Catilina, Big Sur, Monterey, Ventura, Sonoma, and now on Sequoia Beta 7👍🏻

Seems you are extremely lucky with your config, since this thread already have 632 posts. Anyway, this is a Sonoma problem, with some reports that Ventura also suffer the same in minor extent.

There's always at least one which doesn't have any issues like the rest of us, and with that statement for at least 2-3 times in this thread - doesn't contribute at all but braggs (at least in his mind).

At leat we have "ignore this member" option.

Ok, because you are grown up, explain the someones contribution in the thread by commenting multiple times: "I have no issues." How's this info of any use ? Of course I will ignore someone with not useful comments and make the thread cleared up and more readable. You have problem with this, I really don't care.

Since you asked... @flowrider has a system that contradicts the "everyone is effected" narrative, and provides a valuable, factual, datapoint that the problem is more nuanced than some might like to believe. Personally, I think it's healthy that they keep reminding the thread of this, because most new readers to it are not going to start with page 1, they're going to come in at the latest post, and work backwards for a while.

Is it really necessary to post that you are annoyed by some comments? Just ignore whatever you want. But we don't need to know about it.
You are inviting critique by the same standard as you display in your comments

I'm not annoyed, I just don't understand the point of stating multiple times that you don't have an issue. OK, we got it the first time.

"I don't have an issue" is valuable or factual - how ? That helps someone with or without configuration like his - how ?

Or be productive, helpful, give some ideas..... or OK, spam the forum with total irrelevant fact for anybody here.

Glad I found this thread, my NVMe on my McFiver has been randomly ejecting with 14.7 in my 7,1 when not in use, was goin to update to Sequoia soon but will do it today and see if that fixes the issue.

I rejoiced too early. After a month of using Sequoia CPU panic began, the computer freezes during operation, no response, then reboots itself. This is the third time I am sending a report to Apple.
From similar past experience with MP 6.1, it is useless to waste time on tests, the problem is in the system.
Apple, when will I be able to work calmly on 7.1, how many more years must pass before the next bug is fixed?

Whilst I can see why you think that, do you actually KNOW that it's related to the MacOS15 upgrade and/or specifically drives unmounting?
 
Natalia22 said:
The kernel panic appeared after the update to Sequoia, I did not make any changes to the system or hardware. The disks are mounted perfectly.

Would you mind moving these to a different thread, so this one can stay focussed on the drive mount issue?
 
Natalia22 said:
The disk mounting problem is solved, it would be logical to warn MP users that another more critical problem may appear. I apologize if I violate the order, I do not know how to move topics and will not develop the topic of kernel panic here anymore. You can delete my posts.

Yeah, in a different thread, specific to that problem. I'm not a moderator, so I can't change your posts.

That way we keep things neat for folks looking for answers to problems.

Upgraded to 15.2 and it still does not work.
 
Do not update to 15.2 everyone!!

It’s brought back the original issue of startup hangs and raid drives not mounting again 😩😩😩!!!

Now that would be REALLY annoying, I purposely waited at least one revision past the 'fix' to update.
