Not sure if this is the right place to seek help for this issue, but figured it would be worth a try. 

We have started using a Thunderbay with Thunderbolt 3 for SMB file sharing, connected to a brand new M1 mac mini, Big Sur 11.5.x with current version of SoftRAID. We migrated 4x 4TB Seagate disks directly from an older Thunderbay unit to avoid having to copy/reformat/copy back, perhaps this wasn't the best approach. Format is currently MacOS Extended (Journaled) RAID 5

File sharing works fine in general. Users can open files across the network, save, etc. However, when a user copies a file directly to their local desktop, which copies over fine- all permissions are ignored. When the file is opened, an error that the file cant be opened due to permissions issue pops up. It is necessary to either open file from server and "Save As" to the desktop, or Copy the file over and manually add the user privileges via Get Info. Both of these workarounds are fine but not ideal and not expected behavior. In other words, local user account doesn't inherit local user permissions when copying files to Desktop, Docs, etc from the "server" hosting SMB. Its very odd and is happening to all (25) users. 

We recently purchased a second Thunderbay to start from scratch, today we will attempt a fresh APFS RAID 5 if that's possible.

Have you seen anything like this? Any suggestions?

Here is what I would like you to test:

Create a RAID 0 test volume with SoftRAID. See if you get the sharing issues.

Then unmount it and convert it to Apple format and see if the issues are still there.

this seems unlikely to be a SoftRAID specific issue, as SoftRAID volumes are just published like Disk Utility volumes.
