[lustre-discuss] Possible bug in file size reporting

[Kurt Strosahl]

Please ignore... it looks like the user was creating sparse files.

 ll -alsh

878K -rw-r--r-- 1 <user / group> 4.1E Apr 22 01:48 file1
878K -rw-r--r-- 1 <user / group> 6.8E Apr 22 01:32 file2

Good Morning,

   We just came across an interesting issue... three files were created last night that ls reports as having a size in the exabytes (though du shows as being the proper size).

 du -h file1
878K    file1
 du -h file2
878K    file2
 du -h file3
582K    file3

We are running 2.5.3 on CentOS 6.5
