Hi all i have a 5 node cluster where 3 nodes are data nodes, 1 is master and 1 is client node on this cluster when trying to create snapshot i am getting following error ```auto { "error": { "root_cause": [ { "type": "repository_verification_exception", "reason": "[sgpl_backup2] [[Uu67NQqXQVaT1maJ49apng, 'RemoteTransportException[[node72][192.168.1.72:9300][internal:admin/repository/verify]]; nested: RepositoryVerificationException[[sgpl_backup2] a file written by master to the store [/home/sgpl/elasticsearch_backup] cannot be accessed on the node [{node72}{Uu67NQqXQVaT1maJ49apng}{IQI8z2v7QzeohCBSFOZHRA}{192.168.1.72}{192.168.1.72:9300}{ml.enabled=true}].

Home did you mount the shared dir on all nodes? ---

This is my repo path path.repo: ["/home/sgpl/elasticsearch\_backup"] with the help of below command i have given all permission to that repo.path and where sgpl is user of elasticsearch sudo chown -R sgpl:sgpl /home/sgpl/elasticsearch\_backup/ ---

Is this a shared filesystem that is available to ALL the nodes in the cluster at the same path? ---

Yes it is available in all DATA( 3 nodes ) and Master( 1 node ) nodes , but not in client node . ---

You need to have a shared volume, e.g. a NFS volume, behind the repository path that all nodes can access. This means that if node1 writes a file it will be visible by node 2 and node 3. A directory in the local file system will therefore not work, even if the path is identical on all machines. ---
