reiserfs max file test

[Dan Sheffner]

Hello All,

 

I'm trying to find out the number of files that reiserfs can support in a single folder.  I know that you web site says about 1.2 million files without collision, but I have written a small program to create files in order and so far I have been able to create about 10 million files in one directory.  Can you explain collision more? Here is the program I used below to test my theory.  I echo out hello 10 times to each file to give some size. My linux distro is GENTOO 2006.0 version and I'm running kernel 2.16.15

 

 

#!/bin/bash

LIMIT=10000000 # Upper limit of 10 million files 
echo
echo "creating $LIMIT files for test"
a=0

while [ $a -le "$LIMIT" ]
do
echo $a
a=$(($a+1))
touch /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
echo "HELLO" >> /home/thesheff17/installServer/file/file$a.txt
done

 

 

Below is the find command that tells me how many files are in the directory. 

 

production / # find /home/thesheff17/installServer

/file/ \! -type d | wc -l
10000001
production / #
