This is quite frustrating! 1- I want to keep my fedora system (which I can boot choosing the right disk in the bios) untill the debian installation will be finished and configurated. 2- I could unplug the fedora disks.... but, I want to install some debian partitions on these disks (/var, /tmp and swap) to avoid too much writing on the SSDs. 3- Note that the installer message seems faulty: RAID n°2 is concerned by sda and sdb only. 4- The message says that "the following partition tables (sdc, sdd) will be changed" not re-formated. What changes? I don't know! And, still, these disks are not concerned by the LVM on the other disks (as far as I know).... Or this message merely says that a new LVM will be running and something has to be changed/added to take that new LVM into account. In that case the message is inapropriate; how to be sure?
