Hi , Is there any parameter like maxcontig (solaris) in redhat linux? This is the cluster size , and describes the amount of data which is read from the disk . My redhat linux system cant read more than 64 kb. At each read. But one of the sun servers can read up tp 1mb. For eac read operation . This is iostat -x : Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util /dev/sda 14360.14 444.13 977.94 71.53 122701.78 4122.42 61350.89 2061.21 120.85 47.37 4.52 1.70 177.94 here r/s : 977.94 and rkB/s is 61350.89 . This means the system read 62.73 Kbytes per io. I want to increase this value ( so decrease the r/s in order to have better io ) In sun solaris , this is possible by changing the maxcontig parameter using tunefs -a 128 /dev/xxa . Is it possible to achive the same thing in linux?
