I'm going to interpret your question as "Why are there negative consequences when a Linux server is suddenly powered off?", but you English is a bit broken so I'm not sure that's what you are asking. Basically this is the same reason any system suffers from a sudden loss of power: caching. In order to make some slow processes (e.g. hard disk writes) appear faster, allow the system to pipeline actions, and generally increase throughput and decrease response times of the system as a whole, Linux caches data in fast, volatile memory. Unfortunately, all the data in that memory goes away fairly quickly once power is cut. Generally, a Linux system will recover gracefully from the power loss, but no system is able to recover the data that was in volatile memory and no where else. -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
