Sorry, I suppose it must be an stupid question but, what's a "bz"? I 've found several references to it in the list, but no explanation of what it is or how it is done. > > BTW, how much memory does your box have? 48 GB. While fsck was running, there never was more than 5% in use (according to top) and fsck kept its memory use around 3%.
