Hi Kotesh:

 

Gluster Master Site Servers : gluster-poc-noida and noi-poc-gluster

Gluster Slave site servers: gluster-poc-sj and gluster-poc-sj2

 

Master Client : noi-foreman02

Slave Client: sj-kverma

 

Step1: Create a LVM partition of 10 GB on all 4 Gluster nodes  (2 Master) *  (2 slave) and format that in ext4 filesystem and mount that on server.

 

[root@gluster-poc-noida distvol]# df -hT /data/gluster-dist

Filesystem                            Type  Size  Used Avail Use% Mounted on

/dev/mapper/centos-gluster--vol--dist ext4  9.8G  847M  8.4G   9% /data/gluster-dist

[root@gluster-poc-noida distvol]#

 

Step 2:  Created a Trusted storage pool as below:

 

At Master:

[root@gluster-poc-noida distvol]# gluster peer status

Number of Peers: 1

 

Hostname: noi-poc-gluster

Uuid: 01316459-b5c8-461d-ad25-acc17a82e78f

State: Peer in Cluster (Connected)

[root@gluster-poc-noida distvol]#

At Slave:

[root@gluster-poc-sj ~]# gluster peer status

Number of Peers: 1

 

Hostname: gluster-poc-sj2

Uuid: 6ba85bfe-cd74-4a76-a623-db687f7136fa

State: Peer in Cluster (Connected)

[root@gluster-poc-sj ~]#

 

Step 3: Created distributed volume as below:

 

At Master:  “gluster volume create glusterdist gluster-poc-noida:/data/gluster-dist/distvol noi-poc-gluster:/data/gluster-dist/distvol”

 

[root@gluster-poc-noida distvol]# gluster volume info glusterdist

 

Volume Name: glusterdist

Type: Distribute

Volume ID: af5b2915-7170-4b5e-aee8-7e68757b9bf1

Status: Started

Snapshot Count: 0

Number of Bricks: 2

Transport-type: tcp

Bricks:

Brick1: gluster-poc-noida:/data/gluster-dist/distvol

Brick2: noi-poc-gluster:/data/gluster-dist/distvol

Options Reconfigured:

changelog.changelog: on

geo-replication.ignore-pid-check: on

geo-replication.indexing: on

transport.address-family: inet

nfs.disable: on

[root@gluster-poc-noida distvol]#

 

At Slave “ gluster volume create glusterdist gluster-poc-sj:/data/gluster-dist/distvol gluster-poc-sj2:/data/gluster-dist/distvol”

 

Volume Name: glusterdist

Type: Distribute

Volume ID: a982da53-a3d7-4b5a-be77-df85f584610d

Status: Started

Snapshot Count: 0

Number of Bricks: 2

Transport-type: tcp

Bricks:

Brick1: gluster-poc-sj:/data/gluster-dist/distvol

Brick2: gluster-poc-sj2:/data/gluster-dist/distvol

Options Reconfigured:

transport.address-family: inet

nfs.disable: on

 

Step 4 : Gluster Geo Replication configuration

 

On  all Gluster node: “yum install glusterfs-geo-replication.x86_64”

On master node where I created session:

ssh-keygen

ssh-copy-id root@gluster-poc-sj

cp /root/.ssh/id_rsa.pub /var/lib/glusterd/geo-replication/secret.pem.pub

scp /var/lib/glusterd/geo-replication/secret.pem* root@gluster-poc-sj:/var/lib/glusterd/geo-replication/  

 

On Slave Node:

 

 ln -s /usr/libexec/glusterfs/gsyncd /nonexistent/gsyncd                                                      

 

 On Master Node:

 

gluster volume geo-replication glusterdist gluster-poc-sj::glusterdist create push-pem force

gluster volume geo-replication glusterdist gluster-poc-sj::glusterdist start

 

[root@gluster-poc-noida distvol]# gluster volume geo-replication glusterdist gluster-poc-sj::glusterdist status

 

MASTER NODE          MASTER VOL     MASTER BRICK                  SLAVE USER    SLAVE                          SLAVE NODE         STATUS    CRAWL STATUS       LAST_SYNCED   

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

gluster-poc-noida    glusterdist    /data/gluster-dist/distvol    root          gluster-poc-sj::glusterdist    gluster-poc-sj     Active    Changelog Crawl    2018-08-31 13:12:58

noi-poc-gluster      glusterdist    /data/gluster-dist/distvol    root          gluster-poc-sj::glusterdist    gluster-poc-sj2    Active    History Crawl      N/A           

[root@gluster-poc-noida distvol]#

 

On Gluster Client Node at master Site:

 

yum install -y glusterfs-client

mkdir /distvol

mount -t glusterfs gluster-poc-noida:/glusterdist /distvol

[root@noi-foreman02 ~]# df -hT /distvol

Filesystem                     Type            Size  Used Avail Use% Mounted on

gluster-poc-noida:/glusterdist fuse.glusterfs   20G  9.6G  9.1G  52% /distvol

[root@noi-foreman02 ~]#

 

On Gluster Client at Slave site:

yum install -y glusterfs-client

mkdir /distvol

mount -t glusterfs gluster-poc-sj:/glusterdist /distvol

 

Now To Test the Geo Replication Setup:

 

I have copied below file from client at Master site:

[root@noi-foreman02 distvol]# du -sh 17.10.v001.20171023-201021_17020_GPLV3.tar.gz

5.8G    17.10.v001.20171023-201021_17020_GPLV3.tar.gz

[root@noi-foreman02 distvol]#

 

But from last three days it synced to the slave only 5.4GB

[root@sj-kverma distvol]# du -sh 17.10.v001.20171023-201021_17020_GPLV3.tar.gz

5.4G    17.10.v001.20171023-201021_17020_GPLV3.tar.gz

[root@sj-kverma distvol]#

 

I have also tested a another file of size 1 GB only copied from master client and that is still shows 0 size at slave client after 3 days.

Hi krishna,

I see no error in the shared logs. The only errro messages I see are during geo-rep stop. That is expected.

Could you share the steps you used to created geo-rep setup?

Thanks,

Kotresh HR

Hi Kotesh,

 

Below is the cat output of gsyncd.log file generating on my master server.

 

And I am using 4.1.3 version only all my gluster nodes.

[root@gluster-poc-noida distvol]# gluster --version | grep glusterfs

glusterfs 4.1.3

Hi Krishna,

The log is not complete. If you are re-trying, could you please try it out on 4.1.3 and share the logs.

Thanks,

Hi Krishna,

Indexing is the feature used by Hybrid crawl which only makes crawl faster. It has nothing to do with missing data sync.

Could you please share the complete log file of the session where the issue is encountered ?

Thanks,

Kotresh HR

Hi Kotresh/Support,

 

Request your help to get it fix. My slave is not getting sync with master. When I restart the session after doing the indexing off then only it shows the file at slave but that is also blank with zero size.

 

At master: file size is 5.8 GB.

 

[root@gluster-poc-noida distvol]# du -sh 17.10.v001.20171023-201021_17020_GPLV3.tar.gz

5.8G    17.10.v001.20171023-201021_17020_GPLV3.tar.gz

[root@gluster-poc-noida distvol]#

 

But at slave, after doing the “indexing off” and restart the session and then wait for 2 days. It shows only 4.9 GB copied.

 

[root@gluster-poc-sj distvol]# du -sh 17.10.v001.20171023-201021_17020_GPLV3.tar.gz

4.9G    17.10.v001.20171023-201021_17020_GPLV3.tar.gz

[root@gluster-poc-sj distvol]#

 

Similarly, I tested for small file of size 1.2 GB only that is still showing “0” size at slave  after days waiting time.

 

At Master:

 

[root@gluster-poc-noida distvol]# du -sh rflowTestInt18.08-b001.t.Z

1.2G    rflowTestInt18.08-b001.t.Z

[root@gluster-poc-noida distvol]#

 

At Slave:

 

[root@gluster-poc-sj distvol]# du -sh rflowTestInt18.08-b001.t.Z

0       rflowTestInt18.08-b001.t.Z

Hi Kotresh,

 

I have tested the geo replication over distributed volumes with 2*2 gluster setup.

 

[root@gluster-poc-noida ~]# gluster volume geo-replication glusterdist gluster-poc-sj::glusterdist status

[root@gluster-poc-noida ~]#

 

Not at client I copied a 848MB file from local disk to master mounted volume and it took only 1 minute and 15 seconds. Its great….

 

But even after waited for 2 hrs I was unable to see that file at slave site. Then I again erased the indexing by doing “gluster volume set glusterdist  indexing off” and restart the session. Magically I received the file instantly at slave after doing this.

 

Why I need to do “indexing off” every time to reflect data at slave site? Is there any fix/workaround of it?

Hi Kotresh,

 

Yes, this include the time take  to write 1GB file to master. geo-rep was not stopped while the data was copying to master.

 

This way, you can't really measure how much time geo-rep took.

 

 

But now I am trouble, My putty session was timed out while copying data to master and geo replication was active. After I restart putty session My Master data is not syncing with slave. Its Last_synced time is  1hrs behind the current time.

 

I restart the geo rep and also delete and again create the session but its  “LAST_SYNCED” time is same.

 

Unless, geo-rep is Faulty, it would be processing/syncing. You should check logs for any errors.

 

 

Please help in this.

 

…. It's better if gluster volume has more distribute count like  3*3 or 4*3 :- Are you refereeing to create a distributed volume with 3 master node and 3 slave node?

 

Yes,  that's correct. Please do the test with this. I recommend you to run the actual workload for which you are planning to use gluster instead of copying 1GB file and testing.

Hi Kotresh,

 

After fix the library link on node "noi-poc-gluster ", the status of one mater node is “Active” and another is “Passive”. Can I setup both the master as “Active” ?

 

Nope, since it's replica, it's redundant to sync same files from two nodes. Both replicas can't be Active.

 

 

Also, when I copy a 1GB size of file from gluster client to master gluster volume which is replicated with the slave volume, it tooks 35 minutes and 49 seconds. Is there any way to reduce its time taken to rsync data.

 

How did you measure this time? Does this include the time take for you to write 1GB file to master?

There are two aspects to consider while measuring this.

 

1. Time to write 1GB to master

2. Time for geo-rep to transfer 1GB to slave.

   

In your case, since the setup is 1*2 and only one geo-rep worker is Active, Step2 above equals to time for step1 + network transfer time.

 

You can measure time in two scenarios

1. If geo-rep is started while the data is still being written to master. It's one way.

2. Or stop geo-rep until the 1GB file is written to master and then start geo-rep to get actual geo-rep time.

 

To improve replicating speed,

1. You can play around with rsync options depending on the kind of I/O

    and configure the same for geo-rep as it also uses rsync internally.

2. It's better if gluster volume has more distribute count like  3*3 or 4*3

    It will help in two ways.

       1. The files gets distributed on master to multiple bricks

       2. So above will help geo-rep as files on multiple bricks are synced in parallel (multiple Actives)

 

NOTE: Gluster master server and one client is in Noida, India Location.

             Gluster Slave server and one client is in USA.

 

Our approach is to transfer data from Noida gluster client will reach to the USA gluster client in a minimum time. Please suggest the best approach to achieve it.

Did you fix the library link on node "noi-poc-gluster " as well?

If not please fix it. Please share the geo-rep log this node if it's

Hi Krishna,

As per the output shared, I don't see the file "libgfchangelog.so" which is what is required.

I only see "libgfchangelog.so.0". Please confirm "libgfchangelog.so" is present in "/usr/lib64/".

If not create a symlink similar to "libgfchangelog.so.0"

 

It should be something like below.

 

#ls -l /usr/lib64 | grep libgfch

Since your libraries are in /usr/lib64, you should be doing
