Given information such as this: http://www.solarismen.de/archives/5-Solaris-and-the-new-4K-Sector-Disks-e.g.-WDxxEARS-Part-2.html http://article.gmane.org/gmane.os.solaris.opensolaris.zfs/43986 and my last message on the subject in the thread: http://permalink.gmane.org/gmane.os.freebsd.devel.geom/4376 Can you explain why is it wrong, and what can go wrong with changing ashift in this way? _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
