Recovering nodes

To re-add a server node to a cluster, use the couchbase-cli tool and the recovery command with the --recovery-type parameter.

Recovery options are either delta or full.

Table 1. Recovery type
Option Description
--server-recovery=HOST[:PORT] Server to recover
--recovery-type=TYPE[delta|full] Type of recovery to be performed for the node

Syntax

couchbase-cli failover
    --cluster=HOST:PORT
    --server-recovery=HOST:PORT
    --recovery-type=[delta|full]
    --user=ADMIN 
    --password=PASSWORD

Setting recovery type

To set incremental node recovery type for a server:

       
couchbase-cli recovery -c 192.168.0.1:8091 \\	
    --server-recovery=192.168.0.2          \\	
    --recovery-type=delta                   \\	
    -u Administrator -p password

Setting failover, readd, recovery, and rebalance operations

The following example shows a failover, readd, recovery and rebalance sequence operations, where as, a node in a cluster is gracefully failed over, the node is re-added to the cluster, a delta recovery is implemented for the node, and rebalance is performed on the cluster:


couchbase-cli failover -c 192.168.0.1:8091 \\	
    --server-failover=192.168.0.2 \\	
    -u Administrator -p password	
				
couchbase-cli server-readd -c 192.168.0.1:8091 \\	
    --server-add=192.168.0.2 \\	
    -u Administrator -p password	
			
couchbase-cli recovery -c 192.168.0.1:8091 \\	
    --server-recovery=192.168.0.2 \\	
    --recovery-type=delta \\	
    -u Administrator -p password	
				
couchbase-cli rebalance -c 192.168.0.1:8091 \\	
    -u Administrator -p password
