** Summary changed: - the commit interval for the ext3 filesystem should be higher than 5 seconds for laptop users + the commit interval for the ext3 filesystem should be higher than 5 seconds for laptop users by default (at least while on battery)
** Description changed: - The commit interval for the ext3 filesystem should be higher than 5 seconds for laptop users to prevent unnecessary disk-activity when the head is parked or the drive is spun down. ext3 partitions should be mounted with commit=X where X is a number in seconds. - /proc/sys/vm/dirty_writeback_centisecs should be set to the same new interval (in hundreds of seconds). + The commit interval for the ext3 filesystem should be higher than 5 seconds for laptop users (at least while on battery) to prevent unnecessary disk-activity when the head is parked or the drive is spun down. ext3 partitions should be mounted with commit=X where X is a number in seconds. + /proc/sys/vm/dirty_writeback_centisecs and /proc/sys/vm/dirty_expire_centiseconds should be changed appropriately.
