Comment Comment by lyind This nice approach has at least these drawbacks:1. Swapping drives is hard * may be overcome by declaring failure domain = node 2. No powerloss protection advertised to OS, ie. slow synchronous writes * may be overcome by software hacks and whole-system battery supply 3. Potential slowdown on continuous write load (weeks or months, depending on drive) * may be overcome by software in _some_ situations At least the last two points are a no-go for enterprise use-cases, if not addressed. parent lyind 3 years ago
