Since upgrading F26 -> F28 killed my server I decided to build it from scratch. I used a netinstall server DVD and configured everything. It started installing and went to "Creating ext4 on /dev/md/root". Now it has been sitting there for 24 hours.

I have two identical 3 TB disks. I wanted to use them as RAID1: sda1 and sdb1 for /boot, sda2 and sdb2 for swap and sda3 and sdb3 for /. Anaconda accepted the layout and showed the RAIDs.

How should I look for the solution?

Thanks for any help.
