I can defiantly quickly check it out against a windows computer before I plug it back in the next time im at my colo. Ok, so since im about to recompile and force myself to reboot, other than the options SMP that I already added in, is there anything else I really need to look at before I do it again? What about the scheduler? Is the ULE over 4BSD really a big deal? The article I read said that SMP machines really prefer it, is that the case? If there is anything else you would have wanted to teach the last new person you instructed in the finer points of kernel compiling, but didn't... now's your chance!!! cheers, jonathan -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org] On Behalf Of Fabian Keil Sent: Saturday, March 25, 2006 12:13 PM To: Jonathan Horne Cc: freebsd-questions@freebsd.org Subject: Re: USB external drive size limitations?

I believe the limitations described in http://www.freebsd.org/releases/5.3R/relnotes-i386.html are still true: |The MSDOSFS_LARGE kernel option has been added to support FAT32 file |systems bigger than 128GB. This option is disabled by default. It uses |at least 32 bytes of kernel memory for each file on disk; furthermore |it is only safe to use in certain controlled situations, such as |read-only mount with less than 1 million files and so on. Exporting |these large file systems over NFS is not supported. Fabian -- http://www.fabiankeil.de/
