Folks - so currently I have a 8 drive NAS with 12 TB drives with TrueNAS and a Z2 setup.
I would like to upgrade the total storage (who ever has enough?) but I'm not blessed with the kind of money where I can buy 8x 14TB (or larger) drives at one time. I've bought cars for less than that!
So let's say I buy one larger drive a month. (That would be doable on my budget.) I know that if you put in a larger drive into an array of smaller drives, the larger one will only use storage up to the capacity of the smaller drives.
So what's a better call here - is there a way to introduce larger size drives one at a time until the only drives are all replaced, and somehow then rebuild the array to access all of the extra storage space on each of the drives?
Or is it better to just acquire the drives and put them on a shelf until I have 8, then replace them all together, more or less? (Wouldn't this have the samw problem?)
What about creating a new NAS with a new MB and just make it a different pool? That would take longer to buy all the parts, but is potentially doable.
Or is there another option I don't know about here?
TIA.
