Linux kernel is really doing a good job managing memory, but if you prefer to push it in specific direction, there's another tunable with which you can achieve the desired effect: /proc/sys/vm/swappiness Hi, I was wondering if this whould be enought to garanty that everything is written to disk before making a snapshot (block level) of a volume on a SAN (equllogic) or do I have to consider other thing? It only discards clean pages from memory, leaving dirty ones intact.
