Okay, so I've seen this error many times and its cause has always been clea= r. In this case I'm stumped. I've got a 3U SuperMicro server with 16 drives= hooked up to two 3Ware controllers. The drives are configured into two log= ical drives da0 and da1. I've installed a FreeBSD 8.0 OS on da0 but when I = boot the box I'm seeing this error. I've swapped the RAID slots in the BIOS= boot list to make sure the BIOS has the right entry for what I think is da= 0 listed first. I can boot the system with a USB stick and have verified t= hat the OS is installed correctly: root@:~> # mount /dev/da0s1a /mnt root@:~> # ll /mnt total 68 drwxr-xr-x 22 root wheel 512 Dec 2 15:58 . drwxr-xr-x 24 root wheel 512 Dec 2 15:44 .. -rw-r--r-- 2 root wheel 798 Nov 10 06:04 .cshrc -rw-r--r-- 2 root wheel 182 Dec 2 11:39 .profile -r--r--r-- 1 root wheel 6206 Nov 10 06:04 COPYRIGHT -rw-r--r-- 1 root wheel 9 Dec 1 22:31 VERSION drwxr-xr-x 2 root wheel 1024 Nov 10 06:02 bin drwxr-xr-x 7 root wheel 512 Dec 1 22:31 boot dr-xr-xr-x 6 root wheel 2048 Dec 2 11:22 dev drwxr-xr-x 21 root wheel 2048 Dec 2 11:39 etc drwxr-xr-x 2 root wheel 512 Dec 1 22:31 home drwxr-xr-x 3 root wheel 1536 Nov 10 06:03 lib drwxr-xr-x 2 root wheel 512 Nov 10 06:02 libexec drwxr-xr-x 2 root wheel 512 Nov 10 06:02 media drwxr-xr-x 2 root wheel 512 Dec 2 11:39 mnt drwxr-xr-x 3 root wheel 512 Dec 1 22:31 opt dr-xr-xr-x 2 root wheel 512 Nov 10 06:02 proc drwxr-xr-x 2 root wheel 8192 Nov 10 06:03 rescue drwxr-xr-x 2 root wheel 512 Dec 1 22:31 root drwxr-xr-x 2 root wheel 5632 Nov 10 06:03 sbin lrwxr-xr-x 1 root wheel 11 Nov 10 06:04 sys -> usr/src/sys drwxr-xr-x 11 root wheel 512 Nov 10 06:36 tmp drwxr-xr-x 11 root wheel 512 Nov 10 06:36 usr drwxr-xr-x 2 root wheel 512 Dec 2 11:37 var What's more puzzling to me is that I have another identical system that was= purchased a few weeks ago and I have successfully installed the OS on that= box without seeing this error. I'm thinking there might be some kind of BI= OS setting that is different between the two boxes but I'm not really sure = if that explains what's going on. Does anyone have any suggestions what I could do to troubleshoot this probl= em?
