I realize that any solution to this question is likely to not survive between kernel updates and could result in very bad things. Ideas? If support isn't there already (haven't looked at recent xnu), I would've thought it wouldn't be too hard to add, given support for F_NOCACHE in fcntl(2). I can see how something like the AIX 5.1 "mount -o dio ..." could be handy. We're using it for Oracle DBs, it makes quite a difference. With Xserve and Xserve RAID, this "feature" may be somewhat desirable. Cheers, -- Paul Ripke Unix/OpenVMS/TSM/DBA I love deadlines.
