He pasted the entire traceback in his second message, and it looks like the ffs code is where the fault is occuring. Clark confirmed that he was not using a 8:1 frag:block ratio on the MFS partition, so that was probably the problem. He's trying out different MFS settings, and I assume we'll hear back from him once he can determine whether that fixed the problem or not. In the meantime, stop hypothesizing about 4MB pages, and go figure out why the FFS code can't handle other frag:block ratios. :) Mike "Silby" Silbersack To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
