Summary: Unusable/undelete-able directories during tarball
unpacking
Product: Linux XFS
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major
Priority: P2
Component: XFS kernel code
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: smckee@xxxxxxxxx
During a tarball unpacking on an 11TB XFS partition directories are created
which are not deleteable or useable. An 'xfs_repair' will fix the problem.
The directories created during the unpack are in
/atlas/data08/OSG/APP/atlas_app/atlas_rel/12.0.3/gcc-alt-3.2.3/include/c++/3.2.3
umfs02:3.2.3]# ls -al
total 0
drwxr-xr-x 2 usatlas1 osg 41 Nov 28 14:32 ./
drwxr-xr-x 3 usatlas1 osg 18 Feb 3 2005 ../
drwxr-xr-x 1 usatlas1 osg 0 Nov 28 14:32 ctime/
drwxr-xr-x 1 usatlas1 osg 0 Nov 28 14:32 iosfwd/
drwxr-xr-x 1 usatlas1 osg 0 Nov 28 14:32 new/
Trying a particular "directory" gives:
[umfs02:3.2.3]# ls -al ctime
ls: ctime: Not a directory
I am unable to delete this directory:
[umfs02:3.2.3]# rm -rf ctime
rm: cannot chdir from `.' to `ctime': Not a directory
[umfs02:3.2.3]# rm -rf ctime/
rm: cannot lstat `ctime/': Not a directory
[umfs02:3.2.3]# rmdir ctime/
rmdir: `ctime/': Directory not empty
I looked up the i-node info:
[umfs02:3.2.3]# ls -ali
total 0
2147642596 drwxr-xr-x 2 usatlas1 osg 41 Nov 28 14:32 ./

2147648575 drwxr-xr-x 1 usatlas1 osg 0 Nov 28 14:32 new/
In /var/log/messages I find things like:
