Heads up, I think 13.3, does tuesday, will fox some of your issues. And, 13.4, whenever that is out, should address the DART kernel panics.

If there is an issue, I will find it if it does not require a specific app like the Adobe suite.

@softraid-support Yes, they both run Adobe Creative Cloud for my main work. However, my steps to reproduce don’t use the Adobe stack…the issue seems to be triggered by heavy use of a SoftRAID volume (and likely a RAID0 or RAID1+0 volume specifically). The steps above show disk benchmarks triggering a failure, and it is 100% reproducible on the laptop.

Both running Adobe software? Or what?

@softraid-support I understand. I'd love to hear the outcome of your testing...because in my testing (steps above to reproduce) I was able to cause a crash or hang 100% of the time on one system, and ~50% of the time on the other.

We have not seen anything similar in "casual" testing. I will be setting up 4 systems this week, that will run 24/7 with intensive I/O, both HDD and flash to look for any I/O issues. If anything shows up, we will be addressing those issues immediately.

The problem with intermitant bugs is you need to be able to reproduce them in a controlled environment, to be able to identify and fix them.

@softraid-support Just wanted to check if there has been any progress on this issue? I have been using an Intel based Mac for all my SoftRAID needs, but hope one day to return to the M1 Max.

OK, I am researching this, thanks for the details.

@softraid-support Incidentally, after running the same test on a Mac Studio w/M1 Max, I DID eventually get a sort of "stuck" situation with SoftRAID. It was not as dramatic as the array dropping a disk. But the Mac Studio ended up being basically unable to access, mount, or unmount any SR volumes...which eventually led to forced removal of TBT3 cables and forced power off (long power button press). It took many hours to arrive at this situation, but it did get there. I had a second, similar failure later in the day on the Mac Studio when trying to export a video project using Adobe Premiere/Media Encoder. It appears to be the same issue I saw on the M1 Max powered MacBook Pro.

So I have on my desk two M1 Max based Macs that display some flavor of "strange problems" with heavy file I/O on at least two SoftRAID volumes. One is a RAID0 Thunderblade (4 NVME blades), the other is a RAID10 Thunderbay 8 (14TB HDDs x8).

Let me know if you need/want additional support files or other info to try tracking this down?

@higgins

While it could be the Mac, I have a theory that some behavior can trigger a blade to hang/eject.
I asked product management, I can get back to you when I get an answer.
