I'm using FreeNas 8.3.
I have HW raid and I choose using this rather than ZFS mostly for my ability to grow and rebuild my raid6 setup which ZFS cannot do within the same array according to documentation.
I started with 5 drives of 1.5Tb in raid 6 giving 1 disc of 4 Tb as far as Freenas is concerned. I created a UFS volume and filled it with data.
Then I added 6 more drives and rebuilt the array. This gave me a 12Tb drive but my volume under freenas was still 4Tb which is to be expected as I still had to extend the partition and file system which apparently is not something people do.
Some of you might be critical of the choices above but what I'm really looking for here rather than what I should have done is what I should do now.
That's where I am at now, when rebooting the volume does not mount anymore.
The data on the disc could not possibly be conveniently backed up due to the size. I backed what could not be replaced so it is not ultra critical for me to recover it but it would be very nice to and would save me a lot of time.
Anyone has an idea of how can recover from this sorry state and how to grow properly? I have room for 8 more discs and even if I say goodbye to my data and start from scratch I will want to grow in the future.
Thanks for any light you guys can shed.

Here's what I did after reading posts like this one:
I booted in single user
I ran some checks with gpart which told me the table was corrupted
I recovered with gpart:
#gpart recover mfid2
Then I resized the partition:
#gpart resize -i2 mfid2
Ran a check and now have a full 12Tb partition
Tried to extend the UFS FS:
#growfs mfid2
Which returned the error:
superblock not recognized
