We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Choosing the best filesystem for my RAID storage setup. (alien.top)

I am building a video storage server at home, but I have ran into a problem in my plans. My original plan was to use TrueNAS Scale with ZFS and start with a mirrored vdev of two 18TB drives. I then wanted to expand it one 18TB drive at a time into a Z1 vdev of about 5 drives. However I found out from online research that it is not possible to just convert mirror vdev to a Z1 or even expand a Z1 vdev. Does a software raid solution exist where it is possible to start with just two drives, add other drives later and still keep the n+1 topology? This is the minimum I need, however the possibility to add an extra parrity drive would also be amazing. Let's say once I get to 5 drives (4+1) I could add an extra parrity drive to get 4+2. Is this somehow possible? If so what solution should I look into?

the options i know are:

unraid (costs moneybut is the simplest to setup and comes with a bunch of extra features, app store etc)
btrfs (though raid5/6 aren't considered ready for production use)
mergerfs with snapraid (technically not real time but it's the most flexible)
