Assuming your raid array is a mirror, and that you won't be partitioning it or something similar, just adding the existing /home partition to your fstab yes that should work. Although anaconda will not let you touch the mirror member during the install, if you've another disk, putting Fedora 17 on that other disk should work fine, and after that pointing fstab the disk will work. BUT *IMPORTANT IMPORTANT IMPORTANT* you MUST remove the entry from fstab, before rebuilding the array, and then after the rebuild re-add the entry put now pointing to the raid and not to the single disk, otherwise Linux will keep using the single disk for your /home !!!

anacanda: should we ignore the bios raid information on a disk when the raid is broken?
I have a broken fake raid on my machine (intel p67 chipset with one of the disks missing) and when trying to install F17 yesterday (with up-to-date respin done with pungi) I was greeted with the following message disk sdXXX has bios raid information and. blah. is part of a broken raid, ignoring sdXXX. After ignoring the message later on I wasn't given the chance to use the spare disk. I thought of patching anaconda to ignore the bios-raid-information and to allow me to use the disk as I single HDD but I was wondering if there are any side effects out of this? I know that after doing this I will have to manually configure mdadm (and any other raid software) when the second disk arrives. -- joshua -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
