I rebooted my machine today. When it was back up and I ssh'ed in I was really shocked to see most of the directories in the ZFS pool were gone. To my surprise zpool status didn't report any errors.
Now the web interface still reports the correct amount of data in the ZFS pool (2.91 TB used, 612 GB free) but the actual file structure appears to be empty
Really need some help please! I don't want to screw this up, obviously there's some important data on these drives.
