[Gluster-users] Join multiple Gluster Cluster

[Strahil Nikolov]

I guess you can manipulate the peer list and merge them into a single TSP, but I don't know if that would be 'supported'.
Give a try on a setup of VMs and just stop all glusterd and start them after merging the files.

I guess you have to canibilize the clusters, pick the one that has most data and start shrinking the one with most empty space.Once you can't shrink more, you will need downtime to set the 'donor' volume read only and start copying the data to the 'recieving' volume.Once data is moved, move the remaining bricks to the 'recieving' volume and then rebalance.
Repeat again for the other 'donor' volume.

Hi,

I Configured 3 Clusters (For several Shared Homes between different maschines) .. So far no Problem.

Now it need a Volume that going across this maschines, but the nodes are bound to there own clusters so peer probe fails …

  

How i can build one big cluster with all nodes but without dataloss (And best without Downtime J)

  

Hope there is some Pro that can help J
