Ya'll rock. Note, however, that fsync() still serves a purpose with data journalling - without it, your application writes may be sitting in buffer cache, and may be arbitrarily re-ordered before hitting the disk. The fsync() should not return until the blocks have reached the disk (or journal), and thus forms a syncronisation point (which is critical for maintaining sanity of on-disk data structures like skiplists). -- Andrew McNamara, Senior Developer, Object Craft http://www.object-craft.com.au/ ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
