Wondering which NAS box (2-bay) you'd recommend. Here's what I want:
- It's going to store movie files for HTPC use only, so don't care about data loss. At the same time, I'd prefer that a given file is only stored on one disk or the other (if one disk dies, there's no point losing all my movies, just half)
- I don't care about performance (so no striping)
- I'd like a single volume (BTRFS)
- I'd like to be able to expand it easily in the future as follows:
1) Buy new disk. Install in USB enclosure temporarily. Run btrfs-replace to copy the data from one of the internal disks to the USB disk.
2) Remove disk from USB enclosure, install in NAS (replacing the appropriate disk)
3) Run btrfs filesystem resize max /dev/sda to increase the capacity available to my single volume.
Which off-the-shelf NAS will let me do this without fighting me? (Netgear? Synology)? Or do I need to install Linux from scratch and set up everything myself? If so, which box do you recommend for running vanilla (say Debian) linux on?
