[Gluster-users] How to write a volumebackup file with 4 nodes in replica 2

[Davy Croonen]

Hi

We are currently running a gluster cluster with 2 nodes in replica 2. We mount the distributed volume with the gluster fuse client and a volumebackup file for failover.

The volumebackup file looks as follows:

volume node1
  type protocol/client
  option transport-type tcp
  option remote-host 10.0.0.x
  option remote-subvolume /mnt/volume/brick1
end-volume

volume node2
  type protocol/client
  option transport-type tcp
  option remote-host 10.0.0.y
  option remote-subvolume /mnt/volume/brick1
end-volume

volume replicate
  type cluster/replicate
  subvolumes node1 node2
end-volume

We now want the expand our volume with 2 extra nodes also in replica 2. The steps to achieve this are clearly explained in the manual, but what with the volumebackup file? Do we need to change this file and add the 2 extra nodes also or will the cluster manage this internally?

If we have to add the 2 extra nodes to the volumebackup file, do we then have to do this as follows?

volume node1
  type protocol/client
  option transport-type tcp
  option remote-host 10.0.0.x
  option remote-subvolume /mnt/volume/brick1
end-volume

volume node2
  type protocol/client
  option transport-type tcp
  option remote-host 10.0.0.y
  option remote-subvolume /mnt/volume/brick1
end-volume

volume node3
  type protocol/client
  option transport-type tcp
  option remote-host 10.0.0.z
  option remote-subvolume /mnt/volume/brick1
end-volume

volume node4
  type protocol/client
  option transport-type tcp
  option remote-host 10.0.0.a
  option remote-subvolume /mnt/volume/brick1
end-volume

volume replicate
  type cluster/replicate
  subvolumes node1 node2 node3 node4
end-volume

Kind regards
