Hi Yaomin,
>From what I remember both XFS and the rather nascent EXT4 have a higher subdirectory limit. You could probably check ZFS as well.
You can convert your ext3 filesystem into ext4 :
http://ext4.wiki.kernel.org/index.php/Ext4_Howto#Converting_an_ext3_filesystem_to_ext4

These are just pointers as to what you can do, hence please check if the change in filesystem is feasible / appropriate for you, and ensure your data is backed up before proceeding.

All,

    When I use the ext3 as the filesystem on the server, I have a new 
trouble that one directory at most have 31998 subdirectories. Do you have 
any advice for me?

Thanks,
Yaomin
