My server shows very high (98%) cpu iowait all the time via top;
iostat -xtc 5 does not show high disk activities; netstat -i 5 does not show high
Q1. what exaclty does 98% iowait mean?
Q2. how can I find out exaclty what the cpus are waiting for;
mpstat show both cpus wait 98% all the time.
thanks in advance
