I have 4 dell 2970 server , three server  harddisk is 146Gx6 ,one hard disk is 72Gx6:

each server mount info is
/dev/sda4 on /exp1 type xfs (rw)
/dev/sdb1 on /exp2 type xfs (rw)
/dev/sdc1 on /exp3 type xfs (rw)
/dev/sdd1 on /exp4 type xfs (rw)
/dev/sde1 on /exp5 type xfs (rw)
/dev/sdf1 on /exp6 type xfs (rw)

I create a gluster volume  have 4 stripe 
gluster volume create test-volume3 stripe 4 transport tcp \ \  \  \ \

then i mount volume on client
mount -t glusterfs /gfs3
and i dd 10G file in gfs3
dd if=/dev/zero of=/gfs3/3 bs=1M count=10240
10240+0 records in
10240+0 records out
10737418240 bytes (11 GB) copied, 119.515 s, 89.8 MB/s
I am very confused about this
[root at node231 ~]# du -hs /exp4
10G     /exp4
[root at node232 ~]# du -hs /exp4
10G     /exp4
[root at node233 ~]# du -hs /exp4
10G     /exp4
[root at node235 ~]# du -hs /exp4
10G     /exp4
i understand Stripe 4 should hold 1/4 space on each brick,why is 10G on each brick?
can someone explain it,think you.
