Simply put:
background_fsck=3D"NO"
into /etc/rc.conf. That will cause the box to run 'fsck -p'
in the foreground on each reboot.
Alternatively, if this is a one-off, just hit '4' on the boot-up
menu screen, boot into single user mode and run fsck manually.
First, run 'fsck -p' to automatically repair any filesystems marked
as unclean when shutdown. If fsck flails and requests human
interaction then run
fsck /dev/adXsYz
adjusting X, Y and z to suit your local partitioning, and changing
ad to whatever is appropriate if you aren't running on bog-standard
IDE or SATA drives.
Note that it can be quite dangerous to run 'fsck -y' blindly: that
gives fsck permission to destroy otherwise recoverable data if it
needs to in order to get the filesystem back into shape. =20
Once fsck shows all your partitions as clean, just hit ^D to let the
system come the rest of the way up.
Cheers,
Matthew
