I've got a constant 1.4 megabytes/sec of IO read on one server (see iostat output below). What can I do to find which process is the cause ? I already tried iotop and htop, but could not pinpoint the issue with thoses:
Linux 188.8.131.52-x86_64-linode16 (la-machine) 02/16/11 _x86_64_ (4 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 0.16 0.01 0.11 0.68 0.01 99.03 Device: tps MB_read/s MB_wrtn/s MB_read MB_wrtn xvda 42.29 1.39 0.08 568159 30959 xvdb 0.45 0.00 0.00 988 1202
Any hint on either using htop/iotop or another tool to help me find out which process is eating the disk ? (This is a server with 0 traffic currently).
