Check your bootfs and the / file system actually match up. Its quite easy to get odd things happening if you have the bootfs set to a filesystem that then has an fstab which then tells / is on another fs. Also check the loader.conf on the bootfs. In my experiance its safer to have clean fstabs, and nothing in the loader.conf (in relation to this) and just relay on the bootfs pool property On 18 February 2015 at 19:13, X=C4=ABc=C3=B2 <xico@atelo.org> wrote: > Dear freebsd-fs, > > As I am trying to install a new small server with a most partitions on > ZFS, I am running into some little read-only troubles.
