Maybe this would clarify things: Script started on Wed Apr 17 18:23:44 1991 $ df -t | sed -n '/news/,$p' /news (/dev/dsk/c1t5d0s8): 22584 blocks 5997 i-nodes total: 49920 blocks 6240 i-nodes /news/spool (/dev/dsk/c1t5d0s9): 41511 blocks 8238 i-nodes total: 347520 blocks 65496 i-nodes /news/spool/rec (/dev/dsk/c1t5d0sa): 30011 blocks 3340 i-nodes total: 127872 blocks 25568 i-nodes /news/spool/alt (/dev/dsk/c1t5d0sb): 25770 blocks 5807 i-nodes total: 104064 blocks 20800 i-nodes $ exit Script done on Wed Apr 17 18:23:58 1991 See? Each of the spool partitions has up to ~64K inodes. With 3 like this, I could theoretically store up to ~192K articles (not counting directories, etc.) With 4 partitions, ~256K, and so on... Of course, I don't have the space (or the inclination) to store that many articles, so I just run 3 partitions, and "comfortable" numbers of inodes for each. Still, (65496 + 25568 + 20800 = 111864) inodes is quite a bit to play with.
