I'd like to start with a 3TB disk I have and add a second 3TB disk later (couple of months). I should end up with 1 6TB volume (no redundancy - I backup elsewhere anything important).
- What are the correct RAID modes and what are their pros/cons?
- Can I set it up once and then just add the second disk with no data loss?
If data loss is unavoidable when expanding to the second disk then it's annoying, but not a real problem (I'll move everything out, reformat and copy everything back, it will take ages).
Thanks!
