From: Isaac Huff To: freebsd-geom@freebsd.org Content-Type: text/plain; charset=ISO-8859-1 X-Content-Filtered-By: Mailman/MimeDel 2.1.17 X-BeenThere: freebsd-geom@freebsd.org X-Mailman-Version: 2.1.17 Precedence: list List-Id: GEOM-specific discussions and implementations List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 30 Dec 2013 21:40:27 -0000 Is it necessary from a reliability and/or security standpoint to detach GELI volumes before rebooting? Specifically, if I unmount the filesystem, but do not detach (and disable auto-detach) - do I risk data corruption or leakage of private keys during a normal reboot process? Are there any risks at all to rebooting without detach? I have been searching the list archives and can't seem to find a statement either way. Thank you, Isaac Huff
