Alles anzeigenyou looking at it all wrong.
SnapRaid sits on top of FS. you can use any FS you want on the drives and just put them into SnapRaid setup. it is a independent software that, to some degree, emulate raid functionality.
same thing with MergerFS. it is not a file system per see, it is a software layer that aggregate a bunch of disks into a single presentable volume but works on top of existing FS. like an intermediary between them and user shares.
what is great about both a snapraid and mergers is that they work with existing disks with existing FS on them, they are non-destructive to the data, as in you can add drives with data to both on the fly and data will be there for you to use, and you can remove disassemble the pools and data still be there.
you use SnapRaid for data protection and you use MergerFS for have a single pool to work with using multiple hardware disks underneath.
unlike ,what I usually call a real raid, hardware or software, which does 2 things at the same time,
1. pools a bunch of disks into single volume and protects the data on that pool
SR and MergerFS do only one thing each.
SnapRaid protects your data from destruction and keeps you running if a hardware drive fails
and MergerFS allows you to merge (pool) a bunch of drives into a single volume.
Thanks for this clear explanation!
