Cant start up MacStudio with Thunderbay 4 attached

It appears Ventura fixes this issue, finally.

The Promise is a single disk to macOS. that has advantages and disadvantages.

I've just installed the Ventura beta and it does appear to fix the kernel panic - have been able to restart with no issues.  Running a 8-disk Thunderbay which has been problematic for some months.  Fingers crossed that it stays that way!

That’s the good news.  Bad news is that SoftRAID 6.3 apparently will not start up in Ventura.  Am I missing something?

You need to use a beta, we are far from done with Ventura updates.

Here is a link:  http://www.softraid.com/sr_beta

There is a chance SoftRAID won't launch correctly, let me know.

@softraid-support Thanks for this.  I did install the beta version of SoftRAID.  It opened and shows all of my disks - mounted and unmounted.  But I was unable to install the updated driver (it just became unresponsive but was able to force-quit with no apparent damage).  Here's the console log since I installed the new version:

Aug 01 08:33:00 - SoftRAID Application: Launching application: SoftRAID version 6.3.1 b4
Aug 01 08:33:06 - SoftRAID Driver: The SoftRAID volume "Time Machine " (disk17) encountered an error (E00002C1). A program attempted to read or write to a volume which was not open.
Aug 01 13:00:40 - SoftRAID Application: Launching application: SoftRAID version 6.3.1 b4
Aug 01 13:00:54 - SoftRAID Tool: The command 41 encountered the error 1.

Aug 01 13:34:35 - SoftRAID Application: Launching application: SoftRAID version 6.3.1 b4
Aug 01 13:34:38 - SoftRAID Driver: The SoftRAID volume "Time Machine " (disk17) encountered an error (E00002C1). A program attempted to read or write to a volume which was not open.
Aug 01 13:37:02 - SoftRAID Application: Launching application: SoftRAID version 6.3.1 b4
Aug 01 13:37:04 - SoftRAID Driver: The SoftRAID volume "Time Machine " (disk17) encountered an error (E00002C1). A program attempted to read or write to a volume which was not open.

Anyway everything else seems to be working well and I can live without opening softRAID for the time being so I think I will count my lucky stars and keep good backups for the next few months.

We are working on Ventura issues, there are still issues.

Hi, I moved from an Intel iMac to a MacStudio Ultra and I'm suffering the same problem related to the DART issue and with Monterey 12.5  I see that the problem got worse and now even if I wait for some minutes the system crashes immediately after connecting to the Mac Studio the Thunderbolt Raid Drivers...

I read about the 64K stripe workaround but this would mean to move a lot of Terabyte from the current drive which is VERY time consuming... 

Good to see that Ventura could solve the issue but of course it is very unstable yet ... I don't think I have any other chance right now than wait or go for the workaround correct ?

Thank you

Did you try removing one disk temporarily, then pushing it back in after 5 minutes?

Hi Ublaldo.

Did you try the 64K stripe workaround? What were the results?

Are there any downsides to this workaround?

I also have many terabytes to move if I want to rebuild. So, I'd like to hear more first.

Thanks in advance!

Hi softraid-support.

Can you describe this method in more detail or point me in the right direction?

Thanks, Sheldon.

@sheldonmclean 

Take off the front panel on your enclosure.

unscrew any one drive. Pull it out 1 inch.

connect it up.

This will work.

Now after 5 minutes, you should be able to simply push in the drive, without macOS crashing.

64k works in most all cases also, it does not have any significant performance impact.

A clean install works, also, but if you use migration assistant to import data, it generally imports whatever causes the panics.

At least it is fixed in Ventura, macOS 13, coming probably in October, based on past macOS releases.

@sheldonmclean 

I will let him or others answer if they are inclined. But there are extremely few users with the panic on 64k stripe unit size.

@softraid-support Thanks for the quick response!

I'll try the 'remove-a-drive-for-five' method for now.

Is the idea that the ThunderBay won't cause any more panics unless/until you restart?

Thanks, Sheldon.

Yes that is the idea. Works for most all users.
