That makes you prepared for having 228037269 inodes on that file systems. Also, that makes you eligible for a fsck that long. > there are http access logs for half an year. Let's say half a year is 180 days; let's say you rotate daily. Am I right at thinking that you want to be prepared to keep and rotate the http logs of about 1266873 machines daily for the next 180 days? Since when have you accumulated the 8041 inodes that are there now? If you know in advance this filesystem is gonna store apache logs, how big is your typical daily log? From your numbers (331G occupied by 8041 files), it's about 44M per file. How big a block/fragment size do you use on this filesystem then?
