Understand. Remember one thing: hardware RAID adds another point of failure, the RAID controller cards. They do not predict SMART failure, you are limited to specific drives, etc. life is about tradeoffs. But perhaps these choices are better for your situation.

@softraid-support hm I had a Promise Raid Pegasus 6 when it first came out must be 7 years or so ago and only sold it as it only had Thunderbolt 2. Never a single issue beside to occasional HD replacement. given the amount of issues I have with OWC not to mention I can’t use it on my M1 Macs which are out for a while now is so much worse.

@softraid-support interestingly I can actually copy a small file to the drive now, what is the suggestion without losing data?

 

I find it astonishing that you find it acceptable that a machine needs restarting most times after waking up from sleep because of your hardware though.

I do not find it acceptable. It is appalling. And more appalling that we cannot get Apple to address this seriously. This is a kernel bug in macOS. It does not affect everyone, just a minority. And it should never happen. And we force the restart to prevent possible data corruption.

A fundamental rule of disk management in macOS's kernel is a disk is assigned a BSD node number (disk#) when inserted/connected and this number cannot change until the disk is removed. i.e, when you connect a disk it is assigned a number like disk5, and if leave it connected, it should remain disk5. It cannot willy-nilly become disk6. That is what is happening.

And yes, I have seen this with other hardware. I see it far more with OWC hardware, as we ship far drive enclosures than anyone else. It can happen also to USB enclosures, by various manufacturers. It can happen with eSATA drive enclosures, maybe you remember them?

BTW: I have seen this a few times, with the internal drives in a Mac Pro 2012. How is that an OWC hardware issue?

I am not excusing this issue. If there was a magic wand to wave to eliminate this issue, we would. Just like the Thunderbolt disk eject issues, which is another kernel issue or Apple/intel thunderbolt chipset issue. Its just as bad, as Thunderbolt is designed to instantly power off a disk when the Thunderbolt signal is interrupted. Boo for >5 years, on why users have to suffer disks being ejected.

This is one of a short list of critical bugs in macOS that are not being addressed.

I am sure Apple engineering is also under a lot of pressure to release the next great thing, and not given the resources (time) to investigate issues that do not happen for the vast majority because they only have one or two disks connected to their Mac's.

Someone here suggested we work around it. It may be possible, but is probably 4-6 man months of dedicated engineering time, plus debugging, then dealing with the fact we have to maintain a kernel driver. Maybe with the new "driver kit" that is coming, we can do something like this. (drivers like SoftRAID are being moved from the kernel to the user space)

I am not a programmer in any sense, just a support/QA person who has dealt with SoftRAID for a very long time. I make a lot of noise internally about this. And we make some noise through our Apple connections. Nothing has happened on that end.

@softraid-support yes very sad, only I have/had 5 Raids Promise, Drobo, OWC, Terra Master only ever had this happen with OWC. However on my 2019 15k MacPro I had all my raid ejecting itself hence I return the machine after two replacement and bought a Imac which fortunately has not had the ejecting issue. hard to get work done on apple devices nowadays.

Coincidentally we just had contact with an Apple engineering manager who is showing interest in these issues and wants to get them resolved.

Lets hope. I understand Apple is a big ship and takes a lot to make movement, but it would be great if this and several other hanging issues were resolved. In addition to this disk renumbering issue are encryption kernel panics, APFS performance, driver installation issues, disk ejects. If these were all fixed I know I would be a much happier camper!

so would I mate after 25 years of Apple I'm seriously considering moving to Windows, I think that says everything.

You are still a mac Youngster! I have made my living off the Mac ecosystem since the first 100 days in 1984. Quality really was terrible in the 80's and 90's.

When Jobs came back, the late 90's early 2000's much better. Then it has been downhill again. The hardware can be amazing, but bleeping limited and often buggy. The software is running way ahead of itself.

so received my Promise Today installed the drivers launched promises utility set up arraya. KernelPanic...

Restarted array was created so I try to format new array in Disk Utilities halfway in Kernel panic again everything pointing towards soft raid

 

0xffffff8747983ee0 : 0xffffff800d2016a4

0xffffff8747983f60 : 0xffffff800d20bb97

0xffffff8747983fa0 : 0xffffff800cabf13e

      Kernel Extensions in backtrace:

         com.softraid.driver.SoftRAID(6.0.1)[186830B5-EC1E-3D4B-9B79-F26F2307B1FB]@0xffffff7f9301e000->0xffffff7f9305dfff

            dependency: com.apple.iokit.IOStorageFamily(2.1)[95CC5A58-BF77-3690-9EEE-720B18B7C829]@0xffffff7f8d465000

 

Tried again but lugged promise straight in mac not in daily chain still Kernel Panic when formatting.

 

Deleted SoftRaid Drivers

 

voila no issue formatting drive with Disk Utility.

 

Your software is seriously flawed guys.

Soft Raid does not seem to be not compatible with Promise Pegasus Drivers

I do not know of any compatiblity issues. I had tested promise TB2 and TB3 a couple years ago, no issues. Performance was comparable with identical drives, also. Both SoftRAID and Apple drivers are bundled with macOS, so it is unlikely there is a conflict, both companies would be hearing from users and hundreds have both solutions.

That was a short snippet of the crash, but if SoftRAID is involved, then it had to be on a SoftRAID controlled disk. If you were configuring the Promise enclosure when this happened, it makes little sense, unless perhaps the Thunderbolt bus hung.

 

If you are willing, give more details, so I can understand this. Disk Utility has a major bug with SoftRAID volumes, it cannot initialize them, but at least with Big Sur, it just fails, it does not cause a kernel panic.

Promise utilities only work on their enclosure's disks. Then Disk Utility takes over to create the volume, once you create the RAID 5 LUN.

@softraid-support not sure what you need I described all steps the Promis Utility crashed one when creating array but did create it I then could not intialise the new arrays with a disk Utility while SoftRaid drives where installed as it would cause a kernel panic. i tried several Thunderbolt cables and configuration of drive connections direct attached, attached in line with other drives all with the result of a Kerne Panic. I the uninstalled the Soft Raid 6.0.1 and I could initialise the disk without an issue.

What was the version of Promise utility? I can check this, I still have a Tb3 Promise box.

I included a video

https://youtu.be/0MvZQCmDwIw

 

2020 iMac 5K Catalina 10.15.7
Soft Raid 6.0.1 installed

 

I followed these steps

https://kb.promise.com/thread/how-do-i-create-a-volume-on-a-pegasus/

as I swapped all drives from my Other OWC unit which will be sold now over.

1. I installed Promise Utility and Drivers
2. I opened Promise utility created Disk array
3. I created logical drive and Mac Had a Kernel panic and restarted but drives was created.
4. I tried to format new Promise Logical drive with Disk utility and it would always create a Kernel Panic when creating drive.
5. I tried different Thunderbolt 3 configuration of Promise slaved, DAT all same result of Kernel Panic. (watch video posted)
6. Uninstalled Soft Raid 6.0.1 Drivers
7. Formatting of Logical Drive is no issue and proceeded without Kernel Panic
