risk for innodb_flush_method=nosync (5 replies)

Hi,
The msqld on my Linux is busy with hight disk overhead. So I want to know, can I use innodb_flush_method=nosync to descrease disk overhead. I have replication for mysqld on the other Linux without innodb_flush_method=nosync.
if Linux does not crash or poweroff, is it secure for the mysqld with innodb_flush_method=nosync ?
Thanks a lot.
