Freebsd remount disk command example
Type the following command as the root user (superuser):
# mount -o rw /dev/ad0s1a /
OR
# mount -o rw /
Where,
- -o : Takes different options as follows:
- rw : Read write mount.
- ro : Read only mount.
Make sure you replace /dev/ad0s1a and / with appropriate values. See FreeBSD mount command man page for more information.

Your first example did not work for me on FreeBSD 6.1, but if I leave the device off (like in your second command), it does work properly as shown here:
frenzy:~# mount -o rw /dev/ad0s1a /mnt/ad0s1a.ufs/
mount: /dev/ad0s1a: Operation not permitted
frenzy:~# mount -o rw /mnt/ad0s1a.ufs/
frenzy:~#
Thanks for the tip (I’m a Linux geek, so these subtle differences are annoying)!
If you update an entry in fstab you can test it like this
mount -o remount /fstabmountpoint
This will remount ALL mount points mentioned in fstab that are automounted
mount -o remount -a
———————————————————————-
From http://www.manpager.com/linux/man8/mount.8.html
mount -a [-t type] [-O optlist]
(usually given in a bootscript) causes all file systems mentioned in fstab (of the proper type and/or having or not having the proper options) to be mounted as indicated, except for those whose line contains the noauto keyword. Adding the -F option will make mount fork, so that the filesystems are mounted simultaneously.
(ii) When mounting a file system mentioned in fstab, it suffices to give only the device, or only the mount point.
That thing doesn’t work. In my case I needed to remount as noexec.
What works (on my freebsd 6) is:
mount -u -o noexec /tmp
Check the manpage for mount.
Mount -o remount,opts only works on Linux afaik.
