On each requ When upgrading, upgrade clients first, followed by server for all Minor and Patch level changes. +### Resizing the Cluster + +If you need to increase (or decrease) the capacity of a Pilosa server, you can add or remove nodes to a running cluster at any time. Note that you can only add or remove one node at a time; if you attempt to add multiple nodes at once, those requests will be enqueued and processed serially. Also note that during any resize process, the cluster goes into state `RESIZING` during which all read/write requests are denied. When the cluster returns to state `NORMAL` then read/write operations can resume. The amount of time that the cluster stays in state `RESIZING` depends on the amount of data that needs to be moved during the resize process. + +#### Adding a Node + +You can add a new, empty node to an existing cluster by starting `pilosa server` on the new node with the correct configuration options. Specifically, you must specify the [cluster coordinator](../configuration/#cluster-coordinator) to be the same as the coordinator on the existing nodes. You must also specify a valid [gossip seed](../configuration/#gossip-seed). When the new node starts, the coordinator node will receive a `nodeJoin` event indicating that a new node is joining the cluster. At this point, the coordinator will put the cluster into state `RESIZING` and kick off a resize job that instructs all of the nodes in the cluster how to rebalance data to accomodate the additional capacity of the new node. Once the resize job is complete, the coordinator will put the cluster back to state `NORMAL` and ensure that the new node is included in future queries. + +If the node is being added to a cluster which contains no data (for example, during startup of a new cluster), the coordinator will bypass the `RESIZING` state and allow the node to join the cluster immediately. + +#### Removing a Node + +In order to remove a node from a cluster, your cluster must be configured to have a [cluster replicas](../configuration/#cluster-replicas) value of at least 2; if you're removing a node that no longer exists (for example a node that has died), there must be at least one additional replica of the data owned by the dead node in order for the cluster to correctly rebalance itself. + +To remove node `localhost:10102` from a cluster having coordinator `localhost:10101`, first determine the ID of the node to be removed.

Once the resize job is complete, the coordinator will put the cluster back to state `NORMAL` and ensure that the removed node is no longer included in future queries. + +Note that you can't directly remove the coordinator node. If you need to remove the coordinator node from the cluster, you must first [make one of the other nodes the coordinator](#changing-the-coordinator). + +#### Aborting a Resize Job + +If at any point you need to abort an active resize job, you can issue a `POST` request to the `/cluster/resize/abort` endpoint on the coordinator node. +For example, if your coordinator node is `localhost:10101`, then you can run: +``` +curl localhost:10101/cluster/resize/abort -X POST +``` +This will immediately abort the resize job and return the cluster to state `NORMAL`. Because data is never removed from a node during a resize job (only once a resize job has successfully completed), aborting a resize job will return the cluster back to the state it was in before the resize began. + +#### Changing the Coordinator + +In order to assign a different node to be the coordinator, you can issue a `/cluster/resize/set-coordinator` request to any node in the cluster.

Specifically, you must specify the [cluster coordinator](../configuration/#cluster-coordinator) to be the same as the coordinator on the existing nodes. You must also specify at least one valid [gossip seed](../configuration/#gossip-seeds) (preferably multiple for redundancy). When the new node starts, the coordinator node will receive a `nodeJoin` event indicating that a new node is joining the cluster. At this point, the coordinator will put the cluster into state `RESIZING` and kick off a resize job that instructs all of the nodes in the cluster how to rebalance data to accomodate the additional capacity of the new node. Once the resize job is complete, the coordinator will put the cluster back to state `NORMAL` and ensure that the new node is included in future queries. If the node is being added to a cluster which contains no data (for example, during startup of a new cluster), the coordinator will bypass the `RESIZING` state and allow the node to join the cluster immediately.
