Hi,
After a crash, a lot of files on a xfs file system report an empty size
with "ls -a" but not with "du".
xfs_check and xfs_repair don't report any problem to repair (although an
internal log is used) :(
So if I understand correctly, those empty files actually use space on
the disk but are incorrectly reported as empty by the system.
Is there a way to copy back the used blocks to recover the files ?
Example for a previously not empty file:
# ls -l myfile
-rw-r--r-- 1 me me 0 2012-01-24 15:29 myfile
# du myfile
27460 myfile
# du --apparent-size myfile
0 myfile
# xfs_bmap myfile
myfile: no extents
System: Ubuntu 11.04 2.6.38-8-server x86_64
xfs_info /dev/sdc1
