Kjournald - how to determine and change the journaling mode ?
my server is overloaded. As I see kjournald used 48 hours of CPU time within a 26 day period so I may be able to improve the server's performance by switching to another journaling mode. I did search on Google and found many sites of people complaining about kjournald but I didn't find out how to:
1) ...determine which journaling mode my server is using
2) ...change the mode.
