Greetings, Back in 2004 O_DIRECT support was requested, and the response was that it was already on the todo list: http://lists.gnu.org/archive/html/bug-tar/2004-07/msg00017.html
I have run into cache pollution issues causing degraded performance when using tar to copy/un-tar files to an active server, as seems to not be terribly uncommon: http://www.mysqlperformanceblog.com/2010/04/02/fadvise-may-be-not-what-you-expect/ I am wondering what happened to this request, as modern tar still does not seem to support a direct mode, or other options to prevent cache pollution when un-taring large archives. Has anybody else found creative solutions for this situation? Thanks, Aaron
