![]() ![]() ![]() The priority command may be executed at anytime. When the priority command is not specified, or the no priority command is executed, the system uses a default base priority of 100. If the dynamic priority drops to zero or receives an SRRP Advertisement message with a better priority, the SRRP instance transitions to the becoming backup state. Every time an SRRP instances in-use priority changes when in master state, it sends an SRRP advertisement message with the new priority. A VRRP policy defines a set of connectivity or verification tests which, when they fail, may lower an SRRP instances base priority (creating an in-use priority for the instance). The base priority of an SRRP instance can be managed by VRRP policies. If the priority of each router is the same, the router with the lowest source IP address in the SRRP advertisement message assumes the master state. This section describes how task-definition and scheduling can. The router with the best (highest) priority enters the master state while the other router enters the backup state. The Backup Service allows backups (and merges) to be scheduled, as tasks. The SRRP instance priority is advertised by the SRRP instance to its neighbor router and is compared to the priority received from the neighbor router. If Instance metadata service has been specified as the value for Cloud Auth Type, this field is inapplicable, and is no longer displayed.įor AWS, this is the AWS secret access key.This command overrides the default base priority for the SRRP instance. The options are ID and key (which means that an ID and key will indeed be required for communication to be successful) and Instance metadata service (which means that credentials will be sought from the metadata service running in the node’s virtual machine).Įach option assumes that appropriate configuration procedures for the cloud environment have been followed. The type of authentication to be used when communicating with the cloud provider. This should take the form /path/inside/the/bucket. The path of the archive, within the cloud bucket. The bucket in the cloud to which data will be backed up. To use either S3 or S3-compatible storage, select AWS. Instead, the location must be a non-shared directory on the local file system for the node. The pathname of the location must be accessible to all nodes in the cluster that are running the Backup Service but the location itself must be not be shared by NFS or any equivalent protocol. On Linux, therefore, for a filesystem location, use the chgrp command to set the group ID of the folder to couchbase unless a non-root installation has been performed, in which case set the group ID either to the username of the current user, or to a group of which the current user is a member - see Non-Root Install and Upgrade, for more information.Ī directory on the local file system that is large enough to accommodate approximately 10% of the data set that is to be backed up. Note also that Couchbase Server must have read and write access to the location. Locations to be used for saving data must be accessible to all cluster-nodes that are running the Backup Service. Use the following controls and commands to start, stop, or check the status of the Security Console and Scan Engine services. This service stop suddenly and regularly. Provided that at least one node runs the Backup Service, data for the entire cluster can be backed up, restored, and archived. since 2 Weeks our 2 VDP have some problems with the service 'Backup scheduler is not running'. The service (as is the case with all other Couchbase services) can be assigned either when a node is initially provisioned as a one-node cluster (as described in Create a Cluster), or when a node is added to an existing cluster (as described in Add a Node and Rebalance). For backup, restore, and other related tasks to be scheduled and performed, the Backup Service must be running on an assigned node. ![]()
