Description of problem: I have a 3ware 9650-12 controller with 12 320G drives. I defined one large raid array of ~3TB. I then installed FC7 Test 3 with a 2GB SWAP, 200MB BOOT, and the remainder "/" (which would be approx 2.7TB). Install went uneventfully but when the system booted I received a kernel panic. I then used the default LVM configuration, but made the "/" drive 30GB. The system booted fine, but I am now receiving in the startup log: "...very big device. try to use READ CAPACITY(16) and write cache: enabled, read cache: disabled, doesn't support DPO or FUA errors." I submitted a question to fedora-list and was told that I need to use GPT partition tables for partitions > 2TB and that they system couldn't boot from a GPT partition. It appears that anaconda didn't catch this, put the wrong type of partition table on my "/" drive, and then allowed the installation to continue. The problem doesn't surface until you try to boot. Version-Release number of selected component (if applicable): Fedora 7, Test 3 How reproducible: Go thru the install procedure. I did it three ways, using drive defaults (letting anaconda decide), custom procedure without LVM and custom procedure with LVM. The way I got this to work as described above was taking the default drive recommendations and manually changing the size of the "/" partition to 30GB. Steps to Reproduce: 1. Mount the install DVD 2. Proceed with installation Actual results: System won't successfully boot after anaconda installs all the packages. Expected results: Sucessful boot, or at a minimum having Anaconda give some type of warning saying "this isn't going to work" you need to do A. B. C. etc. Additional info:
