yes......a good rule of thumb is 2MB per 1G

.....you should also include performance considerations when designing your
logs, ie striping the logs for improved IO performance

Hi All;

What is the proper size of the JFSLog on an AIX system (either 433 or 5L)?

I have always set it at the default of 1PP. However, I have a colleague
that is saying that "IBM recommends a 2 MB log size per 1 GB of file system
space."

I can't find any documentation stating that either one is correct...does
anyone know where I might find some?

Thank you!
Theresa
