I used F27 beta 1.3 to test if it would work a my computer with an existing RAID1.

As it got to the install screen there was an error 'Device is already in tree'.

There are three reports on bugzilla about RAID issues but it does not seem like they are related to the error message I am getting.

This same error message also happens on F25 and F26.

F24 works.

The is new documentation for F26 and it no longer references this type of problem. The old documentation for F26 refers to the three reports in bugzilla.

Have I missed a work around?

Should I post this the the devel list or some other list?

I have a MSI MB (A78M-E35) with 4gig memory.

Thanks,

David
