Description Ben Turner 2013-10-29 17:05:22 UTC 
Description of problem:

When I try to create a hard link where the source file and the hard link are in the same directory I get:

[root@gqac031 gluster-mount]# ln link-source link-destiantion2
ln: creating hard link `link-destiantion2' => `link-source': No such file or directory

If I run the exact command again it is successful:

[root@gqac031 gluster-mount]# ln link-source link-destiantion2
[root@gqac031 gluster-mount]# sh link-destiantion2
Hello World       
[root@gqac031 gluster-mount]# cat link-source 
#!/bin/bash
echo Hello World

If I create a hardlink where the source and the hard link are not in the same dir it is successful on the first try:

[root@gqac031 gluster-mount]# ln hardlinks-sources/100.sh hardlinks-destination/test
[root@gqac031 gluster-mount]# ll hardlinks-destination/test
-rw-r--r-- 3 root root 29 Oct 29 12:26 hardlinks-destination/test
[root@gqac031 gluster-mount]# cat hardlinks-sources/100.sh
#!/bin/bash
echo Hello World
[root@gqac031 gluster-mount]# sh hardlinks-destination/test
Hello World

Version-Release number of selected component (if applicable):

glusterfs-3.4.0.33rhs-1.el6.x86_64

How reproducible:

Every time I tried.

Steps to Reproduce:
1.  Create a hard link where the source and hard link are in the same directory.
2.
3.

Actual results:

[root@gqac031 gluster-mount]# ln link-source link-destiantion2
ln: creating hard link `link-destiantion2' => `link-source': No such file or directory

Expected results:

The hard link is successful on the first try.
