Hi,
I currently have 1 disk and I want to create home NAS for photo/video storage and installing some apps. I plan in near future to buy another disk to be backup for first.
What should be my steps to make this happen, what layout for pool to choose, how to upgrade later, how to attach this new disk to pool to not lose existing data on first disk?
Buy another cheap and small drive to serve as boot device.
I could be mistaken but I think he has one data disk already (besides a boot disk) and wants to add a second disk to the pool later.
Already have disk for OS.
I take that as confirmation of my interpretation above.
If you create a stripe vdev consisting of one device now you should be able to attach a second disk of at least equal size later, add it to the vdev and therefore create a mirror iirc.
Correct me if I’m wrong please…
How to attach second disk?
Perform a vdev extend operation in the UI to create a mirrored vdev.
It’s a routine operation that is supported in the TrueNAS web user interface. Just start with a single data disk.
If you cannot find the procedure in the documentation, come back when you have that second disk connected.
