NAS Newb.

[ArkahmAsylym]

So I want to expand my computer building ability and thought I'd try to build a NAS....

Now that I got the hardware working, I installed FreeNAS and am ready to set up my disks.  I currently plan 6 - 3TB WD REDS in ZFS.  That will give me 15TB of storage for my PLEX server.  Does this mean I am stuck using 6 drives forever in that pool, unless of course I want to reformat the whole NAS? Or can I add HDD's to the pool and FreeNAS will redistribute the Data?  I realize I can increase storage capacity of the drives individually (letting it rebuild after each replaced drive), but it seems like it would just be easier to fill the NAS with drives.

"In ZFS" mean many things... are these drives in a ZRAID? How are your VDEVs setup? One drive each? you can always add a VDEV to a pool, and a zraid can always resliver onto more vdevs. but be warned, you can NOT remove a disk from a zraid pool.

ZRAID migration and reconfiguration has always been one of ZFS's weak points but it is being addressed.
