Unsupported feature for unknown zpool

[skatedices]

So I have been using this system for a couple of years and worked like charm but the accessing to the drive were extremely slow for a few days. I thought the boot drive was corrupted or something so I freshly clean installed the boot SSD drive without checking the zpool status and all that.
Now I have no longer access to the pool... The pool is "unknown"
Please advice for noob for this situation that makes me so nervous it might loosing all I have.

Code:

root@OSX_Server:~ # zpool import
   pool: Volume
     id: 13332686109870858310
  state: UNAVAIL
 status: The pool was last accessed by another system.
 action: The pool cannot be imported due to damaged devices or data.

Need help on zpool import

Hi all, i use Freenas 9.2.1.5 for a home NAS solution. Since the storage ran out of space (due to my VMware labs) i decided to grow the raidz2 pool (six disks in one vdev) from 2GB to 6 GB each. I raised the ZFS Version from 28 to 5.00 I took the first disk offline, replaced it and resilvered...

My guess : maybe you just installed an older version of freeNAS that was running. If is is the case install the same version as it was running previously.
