Subject: e2fsck discrepancy with debugfs stat ?
Date: Thu, 10 Sep 2015 23:03:57 -0400	[thread overview]
Message-ID: <55F2449D.9090000@yale.edu> (raw)

Hi,
Are there scenarios where e2fsck will report a deleted/unused inode but 
debugfs is able to read the inode structure ?

Some details:
I am using lustre version of e2fsprogs (1.42.12.wc1). When I run e2fsck 
in nofix/dry-run mode on a blockdev, I receive errors about unused inodes.
eg)
 > $ e2fsck -nfv <DEV>
> e2fsck 1.42.12.wc1 (15-Sep-2014)
> Warning: skipping journal recovery because doing a read-only filesystem check.
> Pass 1: Checking inodes, blocks, and sizes
> Pass 2: Checking directory structure
> Entry '131249395' in /O/0/d19 (118843419) has deleted/unused inode 5671802.  Clear? no
etc...

However when I run command debugfs -c -R "stat /O/0/d19/131249395" 
<DEV>, I can retrieve inode contents. Further debugfs "dump" will 
successfully pull the contents (980 bytes) of the file entry.

thanks,
