Hello, I am sorry for having to ask a question you might rate very stupid, but I really want to know it: If you think through system crash scenarios, what types of chrashes are you are thinking of? Do you only consider harddisk faults, or do you consider power failures as well? Or more extreme: Does RAID gives you savety on HD HW failures, but may make things worse for power failures (hard power switch off)? Or more academic: Does raid have some journaling of its dirty cache (and/or whatever would need to be journaled) in a non volatile way, or isn't there any need for it for any tricky reason? thomas - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
