du -s -k differences between two identical directories

[csgonan]

I tarred a directory from a linux server to a solaris server. When I do a du -s -k on the directory, I get almost 150k difference in the file sizes. If I do a ls | wc -l, it is the same. If I look at the size of the individual files, it is the same.

I did an ls on the 2 directories and notice when a directory is within a directories I checking, it can show as 4096 on the linux side and 512 on the Solaris side. Will this alter my results? I do not see any missing files or file size differences. The only difference is the directory size.

I need to make sure these are identical directories?

Any ideas or recommendations?

Thanks

When a directory is created, it has a default size of 512. This expands as files are added to the directory, so what you describe is expected begaviour and will affect your comparisons.

I want to be good, is that not enough?

Sorry, I meant to add that although the size increases as files are added, the reverse isn't true as they are deleted. Think of the value as a kind of 'high water mark' for the directory in question. Recreating the directory and moving the files into it should revert it back to 512 or whatever. Careful with things like database files etc though!
