Well I'd say that's clearly not the problem since so many of us don't have
your issues.  SU is disabled on / for a reason. I highly doubt you actually
want to enable this, but you can if you adjust the FS when it isn't mounted
eg boot from fixit cd.

FreeBSD has defaulted to background checking on SU FS's for the better part
of 10 years.  What version are you running?  What data corruption did you
have and what does databases have to do with it?  Also DB's that are
unexpectly killed can have consistency problems regardless of what FS it
writes to and OS happens to be running it.

User as in you saw it running a couple times?

So on to your actual issue instead of all the bs, what does your
/etc/rc.conf say?  Specifically, what is the boot failing on?

If you really want the disk/partition/slice journaled, you can do so with
gjournal or ZFS offers an even better copy-on-write system.  If the install
is only running a fw, the zfs is probably overkill though.
