Hi everybody,

I have created a distributed dispersed volume on 4.1.5 under centos7 like this 
a few days ago:

gluster volume create data_vol1 disperse-data 4 redundancy 2 transport tcp \
\
gf-p-d-01.isec.foobar.com:/bricks/brick1/brick \
gf-p-d-03.isec.foobar.com:/bricks/brick1/brick \
gf-p-d-04.isec.foobar.com:/bricks/brick1/brick \
gf-p-k-01.isec.foobar.com:/bricks/brick1/brick \
gf-p-k-03.isec.foobar.com:/bricks/brick1/brick \
gf-p-k-04.isec.foobar.com:/bricks/brick1/brick \
\
gf-p-d-01.isec.foobar.com:/bricks/brick2/brick \
gf-p-d-03.isec.foobar.com:/bricks/brick2/brick \
gf-p-d-04.isec.foobar.com:/bricks/brick2/brick \
gf-p-k-01.isec.foobar.com:/bricks/brick2/brick \
gf-p-k-03.isec.foobar.com:/bricks/brick2/brick \
gf-p-k-04.isec.foobar.com:/bricks/brick2/brick \
\
... same for brick3 to brick9...
\
gf-p-d-01.isec.foobar.com:/bricks/brick10/brick \
gf-p-d-03.isec.foobar.com:/bricks/brick10/brick \
gf-p-d-04.isec.foobar.com:/bricks/brick10/brick \
gf-p-k-01.isec.foobar.com:/bricks/brick10/brick \
gf-p-k-03.isec.foobar.com:/bricks/brick10/brick \
gf-p-k-04.isec.foobar.com:/bricks/brick10/brick

This worked nicely and resulted in the following filesystem:
[root@gf-p-d-01 ~]# df -h /data/
Dateisystem Größe Benutzt Verf. Verw% Eingehängt auf
gf-p-d-01.isec.foobar.com:/data_vol1 219T 2,2T 217T 2% /data

Each of the bricks resides on its own 6TB disk with 1 big partition formated 
with xfs.

Yesterday a colleague looked at the filesystem and found some space missing...
[root@gf-p-d-01 ~]# df -h /data/
Filesystem Size Used Avail Use% Mounted on
gf-p-d-01.isec.foobar.com:/data_vol1 22T 272G 22T 2% /data

Some googling brought the following bug report against 3.4 which looks familiar:

https://bugzilla.redhat.com/show_bug.cgi?id=1541830

So we did a quick grep shared-brick-count /var/lib/glusterd/vols/data_vol1/* on 
all boxes and found that on 5 out of 6 boxes this was shared-brick-count=0 for 
all bricks on remote boxes and 1 for local bricks. 

Is this the expected result or should we have all 1 everywhere (as the quick 
fix script from the case sets it)?

Also on one box (the one where we created the volume from, btw) we have 
shared-brick-count=0 for all remote bricks and 10 for the local bricks.
Is it possible that the bug from 3.4 still exists in 4.1.5 and should we try 
the filter script which sets shared-brick-count=1 for all bricks?

The volume is not currently in production so now would be the time to play 
around and find the problem...

TIA and regards,

Joachim
