I use BTRFS and it works fine. Just don't use RAID5/6 and you should be good to go. I've also heard success stories using ZFS on Linux, but I haven't bothered

I use BTRFS and it works fine. Just don't use RAID5/6 and you should be good to go. I've also heard success stories using ZFS on Linux, but I haven't bothered because I'd just rather use something that's in the kernel instead of something outside it.
