SoftRAID 8.3 having issues with MacOS Sequoia 15.1

Hi again,

Sorry to keep asking questions, but I added a new disk, and everything looks good after the rebuild.  However, I have another three drives I want to add as well, so I can phase out the old drives, but the "Add Disk..." option is greyed out.  Attaching a new report.

I assume you mean you want to replace all the disks in the volume? Then you would use "remove disk", pull it out, then "initialize disk", then "Add disk" and let it rebuild. Repeat until all are replaced.

Make sure you have updated backups, for safety.

FYI. I wanted to confirm the MacOS 15.2 Beta does seem to fix the SATA Controller problem with Sequoia. Of course, as a beta some other problems understandably crop up. However, I'm able to transfer large files to/from the ThunderBay 8 enclosure in a RAID-5 set (with at least 7 drives being accessed simultaneously) with no issues. Trying to copy these files to my ThunderBay 8 would previously crash my Mac 100% of the time.

So if the primary concern is using the ThunderBay enclosures with Sequoia, the minor quirks of the 15.2 Beta seem to be well worth the tradeoff.

I'm using 15.2 DB 2, which seems to the same as the Public Beta released today.

So, I can only use 4 of my 8 slots in my Thunderbay 8 for this RAID drive, since I only used 4 to create the RAID in the beginning?  Just wanted to add the 3 new drives into the existing RAID for now, then eventually phase out the old drives over time.  After all, it was always my plan to fill the Thunderbay eventually with drives as I needed more storage.  Sounds like this will not work.  Let me know.  Thanks in advance.

We do not support adding disks, to increase capacity sorry, you wold need to delete your volume and create a new one. Sorry!

@lychee128 
Thanks, yes, other users made the same discovery, that 15.2 fixes this issue, which is great! (we cannot comment before users start publicly commenting, its not that we do not test, we have to wait for public confirmation.)

Thanks for sharing!

I just bought a 14" MacBook Pro (M4 Pro) and plan to hook it to my ThunderBay 8 and ThunderBay 4. Obviously I am running macOS 15.1.

Will this work with 8.3, or am I going to see kernel panics until 15.2 is released?

It will work fine.

I'm running a 2019 Mac Pro with the Sequoia 15.2 release candidate, a bunch of SATA raids and a Thunderbay 8 and so far, so good.

I am having an issue where I could create a RAID set but not delete it or add members to it.

At first it appeared the system was locking up when deleting or adding members to the raid set.

After more investigation I discovered the USB drivers or ports seem to crash or die.

My USB mouse will stop functioning but my bluetooth keyboard continues to function so I can reboot from the terminal to get the USB working again.

Hardware:
iMac Pro 2017
Mediasonic USB 3.2 4 Bay 3.5” SATA Hard Drive Enclosure DAS – USB 3.2 Gen 2 10Gbps Type C
4 x Seagate IronWolf Pro ST20000NT001 20TB

Software:
macOS 15.2
SoftRAID 8.3

Testing:
I was running 15.1.1 when the issue first happened.

Reset NVRAM, still happened.

Updated to 15.2 still happened.

Updated SoftRAID to 8.3, still happened.

Installed 14.7.2 on another disk and booted from that, I could do any operation on the RAID set with no issues.

My conclusion:

I have had other odd USB issues after updating to macOS 15, I use a Focusrite Scarlett audio interface that I have to unplug and plug in on every reboot to get it to be recognized by the OS.

It would seem there are issues with the USB drivers of the macOS 15 release.

Wanted to report here and see if anyone else is having issues with SoftRAID USB drives on macOS 15 Sequoia.

I need a SoftRAID tech support file. (if you cannot attach it, use filetransfer.io and post the link)

@imacer 

Some things that may help in testing this:
if you only have 2 disks, create a non RAID, and convert to Mirror, does that work?

If yes, if you do a 3 drive RAID 5 (only 3 drives in enclosure), does it work?

@softraid-support I actually had to downgrade to macOS 14 so I could keep working, the system was horrible unstable with macOS 15. After going up to 15.2 the USB drivers started to fallback to USB2 making my external enclosures very slow to interact with. I don't think I will want to go back to macOS 15 any time soon sorry.

@imacer 

This is on your iMac Pro, correct? I will make a note to test this, if we can reproduce it with steps, we will report to Apple.
