Do you have any feeling for > whether it is worth changing the journal size? Well, 32MB is small for a write-heavy filesystem. But if you're not seeing any problems with kjournald stalling while it flushes, then it might not be worth the trouble of re-creating the journal as a larger size. It's unlikely to hurt anything, but I wouldn't make it huge priority. Did you also read the LOPSA post from Ted Ts'o that I linked to in the section above the instructions?
