This configuration won't pass sata cache flushing operations from the filesystem to the drive, and so the writeback cache on these drives needs to be turned off to avoid corruption during power failures. This doesn't meant the oopsen are ok, I'm working on a series of EIO patches to get us past these bugs and at least help people read the data off the drives. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
