XFS has the same problem as btrfs: extreme sensitivity to metadata corruption. I'm not sure XFS has the RAID1-for-metadata (DUP) feature like btrfs has recently added.

It's a relatively new feature (Jan-2016) and it's disabled by default for SSD devices (increased wear). Personally I prefer increased wear over unmountable volumes.

I too have lost an entire btrfs volume (single disk) because of a bad sector. It seems btrfs is very sensitive to bad sectors in metadata, compared to ext4.

Since then, I've formatted my btrfs partition to do RAID1 on metadata and haven't had problems since.

  $ sudo btrfs fi df /
  Data, single
  System, DUP
  Metadata, DUP
