Anything in your server/client logs?

Hello.
Thanks for your quick reply.
I reproduced the bug on a newly created gluster volume (connection IP
over Ethernet) with gluster 3.5.0-1:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
SERVER: host07
CLIENT: host01 , host02 , host03 , host04

root@host07:~# service glusterfs-server start
root@host07:~# gluster peer status
root@host07:~# gluster peer probe host01
root@host07:~# gluster peer probe host02
root@host07:~# gluster peer probe host03
root@host07:~# gluster peer probe host04

root@host07:~# pdsh -w 'host[01-04]' gluster peer probe host07
host01: peer probe: success.
host02: peer probe: success.
host03: peer probe: success.
host04: peer probe: success.

root@host07:~# gluster peer status
root@host07:~# gluster volume create scratch01-04 stripe 4
host01:/data/brick1 host02:/data/brick1 host03:/data/brick1
host04:/data/brick1
root@host07:~# gluster volume start scratch01-04
root@host07:~# mkdir -p /storage/scratch01-04
root@host07:~# mount -t glusterfs host07:/scratch01-04 /storage/scratch01-04

root@host01:~# mkdir -p /storage/scratch01-04
root@host01:~# mount -t glusterfs host07:/scratch01-04 /storage/scratch01-04

root@host01:/storage/scratch01-04# ls
root@host01:/storage/scratch01-04# mkdir test
root@host01:/storage/scratch01-04# cd test/
root@host01:/storage/scratch01-04/test# touch foo
root@host01:/storage/scratch01-04/test# ln -s foo my_link
root@host01:/storage/scratch01-04/test# ls -ltr
ls: cannot read symbolic link my_link: No such file or directory
total 0
-rw-r--r-- 1 root root 0 Jun 18 10:07 foo
lrwxrwxrwx 1 root root 3 Jun 18 10:08 my_link


root@host01:~# strace /bin/ls -l foo 2> output_strace_foo
root@host01:~# strace /bin/ls -l my_link 2> output_strace_my_link
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The strace output and the logs of the server and client are attached.
I hope this is useful to pinpoint the problem.
Bye
