Created attachment 1119924 [details] Automatically generated by anaconda Description of problem: Trying to install Fedora 23 Server x86_64 from DVD on a Dell T300 with two 1.5 TB HD and 20 GB RAM. Disks are pre-partitioned, each one with two primary partitions of type RAID autodetect (fd), one of 20 GB for / and the other with the remaining space for /home; sda1 and sdb1 are assembled to form md0, sda2 and sdb2 to form md1, both RAID1. During installation there is no way to specify (like in old Fedora releases) that I want to create the RAID arrays and then to install on the first one. I managed to see reasonable results in the partitioning screen only by working in a shell (Ctrl-Alt-F2) and doing the RAID setup manually. Then I correctly see md0 and I can assign it to / as its mount point, and I can specify to reformat it as ext4; all other options are greyed out. The installation starts, but after a few seconds in fails with a traceback, that I managed to save on /tmp and later copy by manually configuring the network, to copy it on another server on the same LAN; it is attached. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:

The logs show the installer detecting /dev/md/0 (ext4) and /dev/md/1 (lvm pv). You didn't specify which commands you ran on tty2, nor did you say exactly what you saw that led you to believe you needed to go to tty2. Is it possible that the issue is confusion with the new storage configuration screen? Please take a look at the documentation and see if that helps: https://docs.fedoraproject.org/en-US/Fedora/23/html/Installation_Guide/sect-installation-gui-manual-partitioning.html To be clear, it is not going to be possible to create layered devices using pre-existing partitions. You must either let the installer create the partitions or create the volume group yourself. If you are confident there is a bug here, please describe it in detail and provide some screenshots and/or logs to document it.
You are right; I was somewhat confused by the new configuration system, and I mistakenly followed some indications in this article: http://iranzo.github.io/blog/2015/03/28/install-rhel7-on-a-software-raid-device/ where it looked like the only way to install on RAID1 was to set up it manually. I am now installing on a 20GB boot and root ext4 over RAID1 partition, created by only using the storage configuration screen. I will manually create the home partition later, after reboot (xfs over LVM over RAID1). Thank you for the quick and very useful feedback, and sorry for the waste of time. Please close my report, since it's definitely not a bug.
I'm happy to hear you got it sorted out. FWIW you should also be able to create your /home using the installer. You'd make the /home mountpoint, then change its device type to LVM, then set a raid level for the VG in the "Modify Volume Group" dialog, available from the right side while the /home mountpoint is selected on the left.
