This is what I did from the RH 8 box:
for ((i=1;i<=1000;i++)); do mkdir $i; done
ls | wc -l
1000
At your question, I made a 2GB file in 10 directories
(I couldn't create a 10GB file.. a Windows problem?):
for ((i=1;i<=10;i++)); do dd if=/dev/zero of=$i/2GB
bs=1M count=2000; done
ls | wc -l
1000
I can't explain it. Perhaps some weird/corrupt binary
or library? Try
rpm -Va | grep '^..5' | grep -v ' c ' | less
which will show every non-config file that has been
modified since being installed from its original RPM.
Look at libraries and binaries in particular.
Reinstall a damaged RPM with
rpm -Uvh --replacepkgs --force some_package.rpm
paying special attention to any .rpmsave/orig/new
files created, which might move an original conf file
(so diff the *.rpmorig/save/new with the existing
file).
Also, ensure you are seeing the exact same files
missing each time:
ls > missing_at_12-24pm.txt
<later, after umounting/remounting>
ls > missing_at_2-56pm.txt
diff missing_at_12-24pm.txt missing_at_2-56pm.txt
Any differences might tell me to look at intermittent
network connectivity... it's yet another shot in the
dark.
Sorry I could not offer more specific help; these are
the troubleshooting steps I go through when looking at
weird problems like these.
