You're certainly not overlooking anything in CFBSD. I've done some investigation, and it seems that just about nobody is using IDE drives this large. There are plenty of SCSI drives out there, with file systems over 100 GB, but nobody has reported putting FreeBSD partitions of over 32 GB on an IDE disk. We're currently in the process of changing the IDE driver, so it's very unlikely that the one you're using will get fixed, even if there is a bug. I'd recommend to add a second slice to your disk to take up the other 9 GB or so, and put another file system on it. You'd end up with something like this: /dev/wd0s1a 80 MB / /dev/wd0s1b 320 MB swap /dev/wd0s1h 25 GB /usr /dev/wd0s2h 9 GB /var I'd guess that that will work, though we could still be in for surprises.
