Want to configure data center in cluster

[Ganesh Bhise]

HI team,

I am trying to setup bitbucket data center (  on 1st linux system )and bitbucket server ( on 2nd linux system).

I wan to add 2nd server into data-center as a cluster. For that I followed below document :

https://confluence.atlassian.com/bitbucketserver/install-bitbucket-data-center-872139817.html

So as per step 6( 4 shared home ). Provision application cluster nodes I tried to mount shared folder.
After mounting /var/atlassian/application-data/bitbucket/shared folder from data-center server to the node server ( bitbucket server ) at location /var/atlassian/application-data/bitbucket/shared 

After server restart getting below error on bitbucket server( 2nd system ) :

The following problem occurred, which prevents Atlassian Bitbucket from starting:

• Unable to create and acquire shared lock file '/var/atlassian/application-data/bitbucket/shared/.lock' for Bitbucket shared home directory '/var/atlassian/application-data/bitbucket/shared'.
  
  Please ensure that the user running Bitbucket has permission to write to this directory and that file locking is enabled for your network file system.
  
  If this is already the case, please check the logs for more information.

Can you please help me If I am missing something.

You can login to NFS server and give chmod 777 to the folder which you are mounting in other servers. The you don't see any permission issues.

It appears that the user (user account) runs the bitbucket doesn't have write/read permissions to the shared folder which is /var/atlassian/application-data/bitbucket/shared. Can you confirm this by going into above location and create a test file with some test data and see if you are able to do that? If not, then you would have to adjust the permissions on the folder.

I have the same error. I have tested the user and the user does have read write permissions. Not sure how to fix this. 

Is there a solution to this?

[Shankar Asam {Appfire}]

What do you mean by Bitbucket server? Is it a standalone one?

You can't have one node with bitbucket data center and another node with bitbucket server standalone. This is not going to be work. All nodes in the cluster should have a similar version of bitbucket and it must be a data center (not standalone server).

Hey now I have installed data center on both node but still I am getting following error: 
A fatal error has occurred

The following problem occurred, which prevents Atlassian Bitbucket from starting:

Hi Ganesh,

What is the data-center server you're referring to? The shared volume needs to be on an NFS server accessible by all nodes in the cluster.

data-center server mean it's first machine where I have installed bitbucket data center. 

And using NFS I have mounted /var/atlassian/application-data/bitbucket/shared folder from first machine( where  bitbucket data center installed) to /var/atlassian/application-data/bitbucket/shared path on second machine where bitbucket server is installed.

Hi Ganesh,

For Bitbucket Data Center you'll actually need to use an NFS server - how are you mounting this directory at the moment?
