[Gluster-users] No such file or directory in logs

I have a new set up which has been running for a few weeks.  Due to a 
configuration issue the self heal wasnt working properly and I ended up 
with the system in a bit of a state.  Ive been chasing down issues and 
it should (fingers crossed) be back and stable again. One issue wich 
seems to be re-occurring is that on one of the client bricks I get a 
load of gfids don't exist anywhere else.  The inodes of these files only 
point to the gfid file and it appears that they keep coming back.....

Volume is set up as such

root at vader:/gluster/eukleiahome/intertrust/moodledata# gluster volume 
info eukleiaweb

Volume Name: eukleiaweb
Type: Replicate
Volume ID: d8a29f07-7f3e-46a3-9ec4-4281038267ce
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Brick1: lando:/gluster/eukleiahome
Brick2: vader:/gluster/eukleiahome

and the file systems are mounting via NFS.

In the logs of the host for Brick one I get the following (e.g.)

[2014-11-20 23:53:55.910705] W 
[client-rpc-fops.c:471:client3_3_open_cbk] 0-eukleiaweb-client-1: remote 
operation failed: No such file or directory. Path: 
[2014-11-20 23:53:55.910721] E 
0-eukleiaweb-replicate-0: open of 
<gfid:e5d25375-ecb8-47d2-833f-0586b659f98a> failed on child 
eukleiaweb-client-1 (No such file or directory)
[2014-11-20 23:53:55.921425] W 
[client-rpc-fops.c:1538:client3_3_inodelk_cbk] 0-eukleiaweb-client-1: 
remote operation failed: No such file or directory

when I check this gfid out it exists on Brick 1 but not on Brick 2 
(which I am assuming is due to the error above).  Additionally when I 
check for the file that this GFID references it doesn't go anywhere.  
I.e. -

root at lando:/gluster/eukleiahome# find . -samefile 

root at lando:/gluster/eukleiahome# file 
.glusterfs/e5/d2/e5d25375-ecb8-47d2-833f-0586b659f98a: JPEG image data, 
EXIF standard

I have tried removing these files using rm 
.glusterfs/e5/d2/e5d25375-ecb8-47d2-833f-0586b659f98a but eitherall of 
the occurrences haven't been logged in /var/log/glusterfs/glusterfsd.log 
(as I am clearing out all that I can find) or they are re-appearing.

Firstly, is this something to worry about?  Secondly, should I be able 
to simply get rid of them (and I'm being mistaken about them 
re-appearing) and if so, is simply removing them the best method?
