When I boot into the install there is an error in the destination section. I looked at the debug info in the storage.log and there was an error about sdb1 did not exist. But... When I reboot to F24 then ... cat /proc/mdstat md126 : active raid1 sda2[2] sdb2[1] 961261568 blocks super 1.2 [2/2] [UU] bitmap: 2/8 pages [8KB], 65536KB chunk md127 : active raid1 sdb1[1] sda1[2] 15368064 blocks super 1.0 [2/2] [UU] bitmap: 1/1 pages [4KB], 65536KB chunk The section of ks.cfg for hard drive setup is as follows: ignoredisk --only-use=sda,sdb bootloader --location=mbr --boot-drive=sda # Partition clearing information clearpart --none --initlabel # Disk partitioning information part raid.6 --fstype=mdmember --noformat --onpart=sda1 part raid.27 --fstype=mdmember --noformat --onpart=sdb1 part raid.14 --fstype=mdmember --noformat --onpart=sda2 part raid.32 --fstype=mdmember --noformat --onpart=sdb2 raid / --device=root --fstype=ext4 --level=raid1 --useexisting raid /home --device=home --fstype=ext4 --level=raid1 --noformat --useexisting I currently have a raid1 setup with 2 drives sda and sdb Since I am using the option --useexisting do I still need to use the part commands? The last time I did an upgrade was to F24 I have not found anything that says the syntax has changed. Any Ideas? David
