Restore Raid 1 on Mycloud EX2 Ultra

I ended up with a drive failure on a raid 1 array. I also forgot the password to access the NAS. So I reset the device, replaced the bad drive, and logged in. IN the raid profile it shows me “One or more raid volumes are degraded” but doesn’t show me the raid under raid volume.


How do I proceed from here? Do I set up the raid mode first? Is there something else I need to do?
