ext4_dx_add_entry:2024: Directory index full!
http://blog.chinaunix.net/uid-23284114-id-5749136.html
巡檢時，一臺oracle資料庫作業系統/var/log/message日誌中有大量如下warning：
Aug 4 09:18:23 your_hostname kernel: EXT4-fs warning (device sda5): ext4_dx_add_entry:2024: Directory index full!
Aug 4 09:18:23 your_hostname kernel: EXT4-fs warning (device sda5): ext4_dx_add_entry:2024: Directory index full!

Aug 4 09:18:25 your_hostname kernel: EXT4-fs warning (device sda5): ext4_dx_add_entry:2024: Directory index full!
產生warning原因如下：
單個目錄下的子目錄和檔案超過64k個。
經排查，Oracle的adump目錄下有9113975個.aud檔案，將檔案刪除後，warning不再產生。
涉及命令：
1) 統計當前資料夾下檔案的個數
ls -l |grep "^-"|wc -l
2) 統計當前資料夾下目錄的個數
ls -l |grep "^d"|wc -l
3) 統計當前資料夾下檔案的個數，包括子資料夾裡的
ls -lR|grep "^-"|wc -l
4) 統計資料夾下目錄的個數，包括子資料夾裡的
ls -lR|grep "^d"|wc -l
