/etc/fstab /dev/da2p1 /usr/home/hdd ufs rw,nofail 2 2 mount -a mount option <nofail> is unknown: Invalid argument
(In reply to agniaus from comment #0) The error message is correct. This is not an option for the BSD mount command. You are attempting to use a Linux idiosyncrasy. The "nofail" option was invented in December 2007 for the Linux mount command by Matthias Koenig, Kay Sievers, and Karel Zak. (http://comments.gmane.org/gmane.linux.utilities.util-linux-ng/414) The FreeBSD mount command has a "failok" option, dating from base r222832 in June 2011. This is documented in the fstab(5) manual page. It isn't documented in mount(8), however; even though that is the command that actually implements it.
Sorry, I found this option through google by searching "freebsd mount nofail", google give me first result: https://www.freebsd.org/cgi/man.cgi?query=mount&sektion=8&manpath=SuSE+Linux/i386+11.3 Only now I notice that this manual not for freebsd mount :)
