Hi all, Thank's for following up!
The disks are very clearly labeled Corsair, so I believe they are original disks and not OEM. I have no idea why they do not have that WWN number set? The disks were bought as a regular consumer product. I don't really know what that number is, or how it is read from the drives, but could it have an impact that I've enabled UEFI with legacy boot on the system? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876848 Title: Installation of Focal on a linux raid consistently fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/subiquity/+bug/1876848/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
