Or provide them in the first place.

I have use cases for btrfs, xfs and zfs. Somehow ext4 feels legacy or for small systems like Raspberries or when the cloud-image provided is already ext4.

I use BTRFS for personal PCs because of the subvolume feature (since one year or so), ZFS for backup/archive when I need raid and encryption capability without hardware raid and for proxmox. XFS is for large storage servers where hardware raid is already established or very special cases when a lot of inodes are needed.

And no mention of gpg or s/mime support either.

While BTRFS has replaced my long standing affection for EXT4, I also have use for ZFS and XFS.

I use XFS on servers where there is already a hardware raid configured and ZFS where I set up my own mirrors.

If the the one server with XFS I maintain would need a complete reinstall, I am not sure if I would go to ZFS with software raid instead of XFS. I am interested in what you would choose for a raid with 24 harddisks.
