Just a question in regard to when it comes time to set up my system.
I've read various documents and noted that there appears to be only one way to add an additional DISK to a Zpool and that is in a new VDEV.
My board has 6 SATA ports. One will be used for a SSD for the boot drive, leaving me with 5 available SATA ports.
I now have 4 x 3 Tb WD Red HDDs which I will use, and will be using Raidz2 (see I DID read it!) giving me a capacity of 6Tb of storage. This should be more than adequate for now BUT when the time comes to upgrade as far as I can tell the only really option (while retaining redundancy) is to change all of the 3Tb drives to drives of a larger capacity.
From my reading I can't add a disk to an existing VDEV.
Now, I've spent WAY too much money on computers recently BUT would it be a good long term tactic for me to buy a 5th 3Tb drive now so as to have a 5 drive VDEV from the start?
And please confirm my maths - 5 x 3Tb Drives in RaidZ2 ought to give me 9 Tb with 2 drive redundancy.
Suggestions welcome ! Cheers and Thank you.
