Hi , İn Windows I can watch my disks which I have to add disk because it takes too much I/O wait . I know I can watch it via vmstats but in Windows I have a some value and when machine pass this value frequency I know that I have to make some thing maybe increase the disk or I can find out one disk will be damaged in short time ? Does anybody have knowledge about this ?!
