The btrfs wiki Main Page warns that "it is currently possible to corrupt a filesystem irrecoverably if your machine crashes or loses power on disks that don't handle flush requests correctly." How do you know if this applies to your drives? Is there a way to test it, or a model list, or are newer SATA drives (magnetic, not SSDs) always ok? Does it depend on the controller? (I have a SiI 3114, latest BIOS.) I would also be using btrfs on top of dm-crypt (with the latest release kernel). Some kernel versions ago, the message that write barriers aren't supported disappeared; can I assume the device mapper / dm-crypt is not a problem with regards to flushing?
