Hi,Browsing I/O statistics taken by atop on a DB server I came across this curious 10 minute slot where init was apparently causing enormous reads on the system:
PID TID RDDSK WRDSK WCANCL DSK CMD 1/72 1 - 3.3G 428K 0K 63% init
Also it is the top source of I/O since boot 76 days ago:PID TID RDDSK WRDSK WCANCL DSK CMD 1/19 1 - 3.8T 2.1T 1.9G 66% init 30892 - 1.4T 3.1G 139.9M 15% cron 2672 - 57.2G 1.0T 0K 12% oracle
I wonder how that is possible and if it is a bug. The system is Gentoo with sysvinit-2.93 on linux-4.20.17. Ortwin
