We had a power cut. My APC UPS decided that this was the time to start beeping continuously, probably due to an old battery that needs to be replaced. After I reconnected power, my APU2E4 with OPNSense would not start properly. I connected via serial console and saw the following in the eternal boot loop :
>>> Invoking backup script 'netflow'
panic: ufs_dirbad: /: bad dir ino 6250145 at offset 512: mangled entry
I rebooted into single user mode and ran the following:
root@:/ # fsdb /dev/gpt/rootfs
** /dev/gpt/rootfs

Now the system is up and running, but I assume I still need to fix the following issue that was showing in the boot read-out on the console:

What would be the best way to deal with this?
