Dear All,
I was continuously receiving IO waits high usage alerts for our MYSQL 5.6 DB servers running on Ubuntu servers and so checked lots of things to reduce IOs like optimizing queries and shifting database on SAS disks.
But not got any success so tried to split table data (partitioning) but the business logic was not supporting it so started doing RND to reduce IO waits on Ubuntu servers.
And finally got solution and all were happy J
Added below line in MY.CNF
innodb_flush_method = O_DSYNC
Benefits got after adding the line
