- I could use ext4 on all HDDs eventually. But I wonder, can I use ZFS?
Specially I would like to have the ability to expand the single HDD into a Raid once I get the second HDD as painlessly as possible. If I use ext4 I guess I will have to backup/create raid system/reformat/restore the data. I have the idea that zfs only needs to be aware that there is a new drive and it will expand the filesystem accordingly. I'd rather not use LVM. I was burned by it once.
Or, you can use BTRFS, which gives you all the advantages of LVM without LVM https://www.youtube.com/watch?v=hxWuaozpe2I
