linux – ext3_dx_add_entry：目录索引已满

概述背景：我在CentOS 5.3上运行lighttpd 1.4.28-1来提供静态资产. 信号：最近,它有时会变慢.我在内核日志和/ var / log / messages中遇到以下错误： proftpd[5145]: (::ffff:xx[::ffff:xx]) - FTP session opened. proftpd[5145]: (::ffff:xx[::ffff:xx]) - Prep 背景：我在CentOS 5.3上运行lighttpd 1.4.28-1来提供静态资产.

lighttpd的文件根目录是/ data / www / lighttpd,快速计数说我最大的文件夹只包含2k文件：

find . -type d | while read d; do f=`ls -1 "$d" | wc -l`; echo $f $d; done | sort -n

期刊腐败？还有什么可能导致这个吗？

解决方法 我有一个类似的问题,经过快速研究后,我用fsck解决了这个问题,导致我发表了这篇博文： http://rackerhacker.com/2008/10/13/ext3_dx_add_entry-directory-index-full/

注意：我强烈建议在执行与文件系统相关的任何 *** 作之前备份所有数据.
