Hi
Sorry i forgot to include the log message I got when running a
gluster volume rebalance
I [glusterd-rebalance.c:483:glusterd_rebalance_cmd_attempted_log]
0-glusterd: Received rebalance volume 1 on dccbackup

And this is the output of the command
gluster volume rebalance dccbackup start
starting rebalance on volume dccbackup has been unsuccessful
Thx

Look in the gluster logs and see what it says. /var/log/gluster*
If you intention is to migrate data then alternatively you can also do:
gluster volume rebalance VOLNAME start

Hi
Thx for your help.
I finaly could add the last brick .
I now have a Distributed-replicated volume
gluster volume info
Volume Name: dccbackup
Type: Distributed-Replicate
Status: Started
Number of Bricks: 2 x 2 = 4
Transport-type: tcp
Bricks:
Brick1: mysqldccbackup:/export
Brick2: mysqldccbackupmirror:/export
Brick3: gfsbrick1:/brick1
Brick4: gfsbrick2:/brick2
On the client side though I don't see any increasing in storage size.
I tried to rebalance
gluster volume rebalance dccbackup fix-layout start
and got .
starting rebalance on volume dccbackup has been unsuccessful
I'm kind of stuck here.
Thank you
KL
What is the output of:
# ls /etc/glusterd/peers
39bd607b-b355-4e0d-80ae-ef507e0dbabe 4583d8b7-f724-4017-b549-9aa9e27dd50f
a70858c6-cac3-43fa-b743-4d2226f8a433
Above output is mine.
If you cat each of these files, there should be one for each peer OTHER
than the host that your are logged into), and hostnames each files, like
this:
# cat /etc/glusterd/peers/*
uuid=39bd607b-b355-4e0d-80ae-ef507e0dbabe
state=3
hostname1=jc1letgfs15-pfs1
uuid=4583d8b7-f724-4017-b549-9aa9e27dd50f
state=3
hostname1=jc1letgfs18-pfs1
uuid=a70858c6-cac3-43fa-b743-4d2226f8a433
state=3
hostname1=jc1letgfs14-pfs1
Here is a listing of all the peer files on all four nodes of my GlusterFS
servers - I created this configuration in the same way you did - two
servers, then add two servers:

Please send the complete output of gluster peer status from both the
nodes.

hi
Thx for your answer.
I should have mention that I already set up a proper hosts file to avoid
DNS
resolution issue but I still have same issue.
The last brick is allways the one having issues to be added . I tried
adding
gfsbrick2 first then gfsbrick1 and the result is the same
I get
Hostname: gfsbrick2
Uuid: 14f07412-b2e5-4b34-8980-d180a64b720f
State: Peer in Cluster (Connected)
Hostname: gfsbrick1
Uuid: 00000000-0000-0000-0000-000000000000
State: Establishing Connection (Connected)
instead of
Hostname: gfsbrick2
Uuid: 00000000-0000-0000-0000-000000000000
State: Establishing Connection (Connected)
It 's really strange.
Thx
KL
Karim,
gfsbrick1 is not able to contact gfsbrick2 yet. Generally happens
if
the DNS resolutions dont happen as expected. You can map them manually
in
/etc/hosts for both the machines?.
something like:
on gfsbrick1
<ip-of-brick2> gfsbrick2
on gfsbrick2
<ip-of-brick1> gfsbrick1
Pranith.
