History: root filesystem ([active]) has been rapidly full (At nomadBSD’s install, I had chosen automatic partitioning) by installing ports.
Why: So, I decided to fusion / and /home in a same partition because /home was weakly occupied.
Implementation: I’ve backed-up /home mounted fs to be free to delete its partition and restore space for the active partition.
I’ve expanded the root partition close to the end of the media.
Final step, to grow root filesystem. This is where I am. This is my trouble.
Note 1: All these steps have been performed under another bsd system. This explains why root filesystem to expand (/dev/ada1s2a) is showed mounted at /root/rootdisk on screenshot.
Note 2: I’ve tried growfs with /dev/ada1s2a unmounted as well.
Sorry, if I made you misunderstood.
Thank you for your patience.
