Description

A problem exists in Linux after a file recovery (e2fsck) leaving some of the recovered files with corrupt file attributes (lsattr). This causes any file modification or deletion to fail, even as root.

History

In order to remove the two file attributes needed for file deletion by root use the chattr command with the -a and the -i flags on the file to change the *A*ppend and *I*mmutable file attributes.

chattr -i -a /path/to/some/file

When the command finishes delete or modify the files normally.

#2 Updated by Daniel Curtis over 7 years ago

Some attributes include:

  • A - don't update atime
  • S - synchronous updates
  • D - synchronous directory updates
  • a - append only
  • c - compressed
  • d - no dump
  • i - immutable
  • j - data journaling
  • s - secure deletion
  • T - top of directory hierarchy
  • t - no tail-merging
  • u - undeletable
  • I - use hashed b-trees for directory lookups
