Red Hat Bugzilla – Bug 149061
ext3 gets i_size/i_blocks wrong on short O_DIRECT write
Last modified: 2012-06-20 12:05:38 EDT
Description of problem:
On a short O_DIRECT write --- for example, when a large write is submitted but
the fs fills up halfway through --- disk blocks get allocated but the file's
i_size is not updated. This leads e2fsck to conclude that i_size is wrong on a
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. write 1MB blocks with O_DIRECT until the fs fills up
Pass 1: Checking inodes, blocks, and sizes
Inode 12, i_size is 1889019101184, should be 1889019604992. Fix? yes
Not massively urgent --- it's really just a cosmetic issue --- but I'm opening
the bugzilla so it doesn't get forgotten about completely.
