Once, when turning on my FreeBSD 10.2 Desktop, I saw this panic error: ufs_dirbad: /usr/user/home: bad dir and the system did not start.
I was scared for the disk, I thought it was unusable.
But when I ran the fsck -y command in the single, it went without problems.
I rebooted and rebooted in single.
And the following helped me.
Let's see what you are registered in the fstab file
this can be done by executing the command
# cat /etc/fstab
Let's see how the partition is mounted /usr/user/home I have it mounted on the device /dev/ada1p2
Let's run the file system check again only now like this:
# fsck -t ufs - y /dev/ada1p2
Now fsck finds errors and fixes them, reboot.
After rebooting my FreeBSD Desktop booted without problems and mounted /usr/user/home
To automatically start fsck, add in /etc/rc.conf the following:
fsck_y_enable="YES"
