Well it worked and then I screwed myself...
I created a new folder called "extent" inside of Vol1. I then cut and pasted the extent into the folder, and updated the ISCSI extent and everything was working, including the mount. I had also created a test extent folder with a mount. The mount started working and I saw it in Crashplan. I did not want to use a folder called "test" as my mountpoint, so I changed it to "extent". I then deleted the mount folder called "test" and when I did this, it deleted my extent. I cannot see it, but for some reason a VM that I am running off of the ISCSI target is still running, so I know the data is still working but I cannot see it in FreeNAS.
Any ideas on how I can fix this? Part of me says reboot, but another part of me says if I reboot I may lose my chance at recovery.
