centos下一个文件无法删除

dengbao2001

find 后面的路径不要写/,就写当前文件的目录

另外，讲strace的调用结果贴出来看看

还有isof结果

    查了一下，没有被别的程序锁定，发现他的上一层目录，有个I的属性：
   ----------I--e- ./201411

dengbao2001

是不是chattr之，如果是 i：设定文件不能被删除、改名、设定链接关系，同时不能写入或新增内容

你得取消掉他的属性

dengbao2001

如果用strace 追踪，是可以看到相关错误信息的，我就安装刚才的做法，建立一个123文件夹，里面放一个123.txt 文件。 123文件夹加i属性，删除123.txt提示Permission denied

就知道是权限的问题

    chattr只能取消i的属性，不能取消大写I的属性


一下是strace的内容：

用echo 看看能不能追加数据进去

The ’I’ attribute is used by the htree code to indicate that a directory is being indexed using hashed trees.  It
       may not be set or reset using chattr(1), although it can be displayed by lsattr(1).

    不能追加数据，提示权限不够，我目前是root权限
