(Also, the number of inodes is fixed, which would be painful if we could drop the block size...). A quickie shell script tells me that: (total size in 4k blocks)/(total # of bytes in files) = 2.0 On a Sun with 1k blocks the number is 1.2. For us, this is unacceptable, so I guess I'll have to scare up some disk space on a Sun somewhere. Too bad, because otherwise things worked quite well. This ignores the role of fragments, which I would have thought would go a long way to saving the day for AIX. Since I observe a lot of wasted space, I gather it isn't. Strange.
