Hi,
I am a beginner in distributed file systems and I currently work on Glusterfs.
I work with 4 VM : srv1, srv2, srv3 and cli1
I tested several types of volume (distributed, replicated, striped ...) which are for me JBOD, RAID 1 and RAID 0.
When I try to make a dispersed volume (raid5 / 6) I have a misunderstanding ...
gluster volume create gv7 disperse-data 3 redundancy 1 ipserver1:/data/brick1/gv7 ipserver2:/data/brick1/gv7 ipserver3:/data/brick1/gv7 ipserver4:/data/brick1/gv7
gluster volume info
Volume Name: gv7
Type: Disperse
Status: Created
Number of Bricks: 4
Transport-type: tcp
Bricks:
Brick1: ipserver1:/data/brick1/gv7
Brick2: ipserver2:/data/brick1/gv7
Brick3: ipserver3:/data/brick1/gv7
Brick4: ipserver4:/data/brick1/gv7
gluster volume start gv7
mkdir /home/cli1/gv7_dispersed_directory
mount -t glusterfs ipserver1:/gv7 /home/cli1/gv7_dispersed_directory
Now, when i create a file on my moint point (gv7_dispersed_directory) :
cd /home/cli1/gv7_dispersed_directory
echo 'hello world !' >> test_file
I can see in my srv1 :
cd /data/brick1/gv7
cat test
hello world !
in my srv2 :
cd /data/brick1/gv7
cat test
hello world !
in my srv4:
cd /data/brick1/gv7
cat test
hello world !
but in my srv3 :
cd /data/brick1/gv7
cat test
hello world !
hello world !
Why?! output of server 3 displays 2 times hello world ! Parity? Redundancy? I don't know...
Best regards
Alex
