Why did you remove the existing drives in the first place, if the intention was to add an additional drive?
Software, hardware, or fake RAID config?
That does not exactly tell what was on the drives. Which parts of the directory tree were on the array? All (i.e. no separate system drive)?
One can take AlmaLinux installer image, boot with it, and select Troubleshoot/Rescue. That way one runs a minimal OS (from USB) and can check what it sees on the hard drives.
