X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 14 Feb 2010 00:24:32 -0000 Hello >From the SUN ZFS Administration Guide: http://docs.sun.com/app/docs/doc/819-5461/gaztn?a=view "If ZFS is currently managing the file system but it is currently unmounted, and the mountpoint property is changed, the file system remains unmounted." This does not seem to be the case in FreeBSD (8.0-RELEASE): ================================= zfs get mounted tank/home NAME PROPERTY VALUE SOURCE tank/home mounted no - zfs set mountpoint=/mnt/home tank/home zfs get mounted tank/home NAME PROPERTY VALUE SOURCE tank/home mounted no - ================================= This might not look like a serious issue at first, until you try doing an installation of FreeBSD from FIXIT, trying to setup multiple filesystems and their mountpoints at the very end of the installation process. For example if you set the mountpoint of your poolname/rootfs/usr to /usr as one of the finishing touches to the system installation, it will immideately mount the filesystem, instantly breaking your FIXIT environment and you cannot proceed any further. Is this a known issue and/or should I submit a PR? - Sincerely, Dan Naumov
