NAS HDD Upgrade

[mmcbj5]

I am new to freenas and dont know musch on how it works

I am looking to build a Freenas Server that will start with 5 drives 10TB NAS drives and expand to 24 in over the next year or so as i need the drives and the funds become available.

Is their a way to add HDD's to a current volum and keep the RaidZ2 for all the drives.?

because online the only way i found was to rebuild the RAID to add the drivres in.

This would not be possible as i have to much data to copy to an external drive 

 

I could not find anything on new versions of freenas for this that is why i am asking for some help

 

Thanks

EDIT:  go down one reply, his is much better.

 

I am fairly certain you cannot add drives to an existing zpool.  Changing the size of the zpool requires redoing everything and your data will be lost on those drives.

You can create an array and then add another array to the first. So if you have a RAID Z2 array you could add a second RAID Z2 array to create a single volume without erasing the first array (so you would end up with two RAID Z2 arrays and four redundant drives), but you couldn't add any drives to the first RAID Z2 array without formatting it.
