That's good to know, I'll have to look into it.

Thanks for your reply - that's what I was afraid of.  It would sure be nice if there was a supported solution because drive sizes are going to push us to EFI eventually.

So, the way to solve that is with EFI drivers. Similar to https://efi.akeo.ie/<https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fefi.akeo.ie%2f&c=E,1,K9LhEBZlkezYDfNFdYDWU_Uk7Hh-TppSXfmwuB8QU9bqVYwbtggGheXDQ3mWIJP6s2cCbhPvUZcEG7Ogc4rBWin35a39dApQVxO_WkqI&typo=1>

It's unlikely that vendors would ship those out of the box however.

I've looked at this before.  To my knowledge, there is not a really good solution.
Kees Cook described the problem and some options
https://outflux.net/blog/archives/2018/04/19/uefi-booting-and-raid1/<https://linkprotect.cudasvc.com/url?a=https%3a%2f%2foutflux.net%2fblog%2farchives%2f2018%2f04%2f19%2fuefi-booting-and-raid1%2f&c=E,1,sPdCxbKO2HDHcP-bbk3EN6JdQpX7jMXnERXONXkjVW9gcqIJsy_rQpwDrCLOO088DKzFTvST0I8MGFArmP6CMG1P0zulW3nKESbdQuRU&typo=1> .

It'd be nice if there was a supported "right way" to do this.

I have tried unsuccessfully so far to set up software RAID 1 while installing 16.04 or 18.04.  I was able to get install to finish a 16.04 install by manually creating a EFI partition during the process but the system won't boot (HP DL380 Gen 10).  In doing research I'm seeing that the EFI specification doesn't address mirroring.  However, references were in the Ubuntu 12.04 era.

Is this still true?  Can I have both EFI boot and RAID 1 for the EFI partition?

If the install is successful are there things I can check/correct to get a successful boot?

This is being set up for a customer at a remote site, is it even advisable to do RAID 1 on UEFI or is it best to do legacy BIOS for support reasons.

Thanks for your help.
