How is it possible that cp didn't copy all files from a huge directory?

I did cp on a large directory with 5000 files. I checked contents with diff and it was not matching! How is this possible?

I ran cp -rv devholidayge/ holiday/

Are you sure it completed with a 0 return code and no errors? What is the exact command you invoked? – dset0x Oct 16 '12 at 10:12
Does the directory have subdirectories under it? If yes, then cp by itself will not do a recursive copy unless you specify the -R flag. – M K Oct 16 '12 at 10:15
Did you run out of space on the target? – pjc50 Oct 16 '12 at 10:20
@MK yes I used -r – Oct 16 '12 at 10:34
@pjc50 nope. I've many more gigs of space. – Oct 16 '12 at 10:34
@zmode exact command is in the post. I edited it out. – Oct 16 '12 at 10:35
Are there subdirectories or files within devholidayge/ for which you don't have read permission? – M K Oct 16 '12 at 10:36

What do the files that didn't copy have in common (if anything)? Were they all over a certain size? Were they all a certain type? – ChrisF Oct 16 '12 at 10:36
@ChrisF they were part of the w3 total cache plugin. – Oct 16 '12 at 10:40
@SandroDzneladze - edit this information into your question. – ChrisF Oct 16 '12 at 10:41
@SandroDzneladze Could it be that they were cache files? If so, it is possible that they vanished or were created after the copy started. – dset0x Oct 16 '12 at 10:41
@zmode not possible, they were part of w3-total-cache-config files not cache files. – Oct 16 '12 at 10:50
