It depends..  did you gpart it first and the geli it? or the other
way around?

If you gpart'd it first, you should be able to see your partitions,
if you can't then getting a replacement controller card makes the
most sense, as it's likely that the RAID card meta data is at the
begining of the drive...

gpart also supports the resize command...
