Thank you for posting that.

Do you understand the difference between RELEASE and STABLE?

I do not understand how your system can work at all if the root 
filesystem is mounted at /mnt (?).  Is your FreeBSD running on a 
different disc?  Do you have a multiple system disks, multi-boot, etc.?

Please post your console session.

Please run the following commands and post the console session:

# camcontrol devlist

# gpart show

# mount

# zpool status
