Hi all. I just installed 4.10 (and upgraded to 4.10-STABLE) on a 2 x 9GB SCSI disk AMI MegaRAID array (RAID0). I set up slices as I have previously with 30GB+ IDE drives: 1GB swap 29GB / Fdisk, label and the rest of install went fine, as did the update, but on all reboots (even before the update) I got the following error: Disk error 0x1 (lba=0x21fc09f) No /boot/loader >>> FreeBSD/i386 BOOT Default: 0:ad(0,a)/kernel boot: If I hit enter, it spit out this error: WARNING: loader(8) metadata is missing! and continued the boot process. After finding all the devices, including the RAID controller (amr0) and the logical drive (amrd0), it displayed a 'mountroot>' prompt. If I gave it the logical drive slice a: (ufs:/dev/amrd0s1a) it finished the boot. I got around the problem by doing two things: 1. Created a /boot.config containing "0:da(0,a)/kernel" After doing this, the boot2 stopped complaining about a missing /boot/loader, which makes sense because I'm telling it to load /kernel instead of /boot/loader. 2. Built a new kernel and defined ROOTDEVNAME=\"ufs:amrd0s1a\" Now I'm no longer prompted to specify the root slice. So things are good. My machine boots w/out interaction. But I'm still perplexed as to why it didn't before. If boot2 can find /kernel, why can't it find /boot/loader? To further investigate, I copied /boot/loader to / and changed /boot.config to '0:da(0,a)/loader' and whaddya know? It now runs the BTX loader properly. So what's going on? Can anyone answer this stumper? Thanks, Brad
