I just found this project by browsing the mergerfs documentation. It claims to be an opensource fork of the Unraid software that makes it so flexible. The documentation isn’t great, but has all the basic info to get going. It works kinda like Snapraid in that each disk has it’s own filesystem and parity is calculated across all of the drives, but it happens in real time (unlike with snapraid).
Thoughts? comments? Would you trust this with important data?
What is the gain compared to running something battle tested like zfs or mdraid?
The selling point of unraid is that you can mix and match different disk sizes and it figures out a (good, efficient?) way to handle them even as you grow a pool. You’re not going to have a good time with a 1TB drive, a 2 TB drive and a 15 TB drive using zfs, unraid doesn’t care… (Using and preferring zfs myself, by the way; this is heresay.)
Ah, I can see the appeal but it’s not for me then. :)
