Namely, doing so causes volumes to be Read-Only.
SoftRAID says the volume is fine, no errors, validates, etc.

All indications point to this being an Apple issue, via the fsck_hfs binary being built with a developer runtime that isn't included within the OS Update. As such, I expect this is something Apple will need to fix on their own vs something that SoftRAID can fix in the meantime.

If affected, this is what the user sees:
macOS reports that the drive is corrupted and must be mounted Read-Only and suggests backing up and re-formatting.
DiskUtility First Aid reports:

I can still access the data, but how do I access the missing NVMe drive? The volume is shown as degraded without any errors.

I installed the recent SoftRAID (Version 8.6.1) for my 8 drive OWC enclosure, and the software freezes on launch, with the error:

"SoftRAID Error: An internal part of the SoftRAID Monitor has stopped functioning properly. Please quite SoftRAID and relaunch it."

However, doing so puts me in another error. No amount of relaunching resolves the error.

I'm on Tahoe 26.2

Thanks!

I upgraded my ATTO drivers and ATTO360 app to the latest version to those that are Tahoe-compliant. Once rebooted into Tahoe, I immediately started to get errors from SoftRAID across every drive.

I did a clean install of macOS Tahoe thinking that past ATTO kexts may have been left around and were at fault, but it didn't help--the same error messages still showed up.

The RAID volume still shows up and my data appears to be intact. However, I'm afraid to access or use the RAID until I can get SoftRAID working properly. I'm uploading some example images of the drive errors. Also including an image of the SoftRAID log.

Is there a new version of the software or a beta that resolves this?

Can no longer mount the drive. Always been set up as a RAID 0 from factory. 

Fortunately I have no important data on it - but it's not letting me do anything. I can't erase, create a new volume etc, and does not mount whatsoever?

Please advise? I just wanted to erase it and create an empty drive.

All features are available and functioning.There is no risk to your data or volumes. All other functions are 100% active.

You can re-enter your license number to reinstate Premium mode, or ignore this (use SoftRAID in trial mode) for now.


An update, SoftRAID 8.6.1 is being tested and should be released very soon.
