[Gluster-users] I am very confused about strip Stripe what way it hold space?

[肖力]

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 \
172.16.20.231:/exp4 \
172.16.20.232:/exp4  \
172.16.20.233:/exp4  \
172.16.20.235:/exp4 \


then i mount volume on client 172.16.20.230
mount -t glusterfs 192.168.106.231:/test-volume3 /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.
