I am planning on creating a home server with either 2 (RAID1) or 3 (RAID5) HDDs as bulk storage and 1 SSD as bcache.
The question is, what file system should I use for the HDDs? I am thinking of ext4 or xfs, as I heard btrfs is not recommended for my use case for some reason.
Do you all have some advice to give on what file system to use, as well as some other tips?

Btrfs still has some issues, but it’s not like it’s dangerous or anything.
Xfs is going to give more flexibility for managing volumes, better performance than ext4 across multiple disks, and more fault protection.
Ext4 doesn’t really have any benefits in this race but being stable I suppose. An argument could be made it might be slightly faster under LUKS.
Zfs is more complex, but a bit more flexible than XFS, has CoW, snapshots, built in encryption and dynamic storage allocation.
