High Utilization after installing NSS
High Utilization after installing Cluster Services on OES Linux
top shows high load average
To know if there is something else contributing to the high load average, you'll want to check the actual CPU usage (top shows this as well).
To see how the NSS / NCS threads are contributing to the load average, do the following from within top:
1. Press SHIFT-F. This brings up the possible fields top can sort by.
2. Press the W key, then return. This sorts by Process Status.
3. Press SHIFT-R. This reverses the sort, so that hopefully the processes with status 'D' are at the top.
The novell processes with 'D' status (the MPK processes are novell processes) are each contributing approximately 1.0 to the load average. So, if you have 4 processes in that status, subtract 4.0 from your load average to get your real load average.With OES2SP2, MPK calls were removed from the Novell Cluster Services code. The MPK calls were replaced with POSIX and Linux functions. These changes were made in support of the MPK calls being removed from the Novell Storage Servicesâ¢ (NSS) file system software to achieve performance enhancements for the NSS file system.
