System Requirements for MongoDB

Verify that your environment meets the system requirements.

All Environments

• All instances must run with configuration files in the YAML format.

• If the ports between the master node and the other cluster nodes are blocked, the nodes must connect through a firewall.

Linux Environments

• Database authentication is supported on both Windows and Linux for full backups. Authentication is supported only on Linux for incremental backups.

  The user account that you authenticate with must have one of the following role or roles on the admin database:

  • The root role. This is a superuser role.

  • A set of roles (backup, restore, clusterMonitor, hostManager). If you do not want to assign the superuser role to the database user, then use these roles.

• Logical Volume Manager (LVM) volume groups must have adequate free space for creating the IntelliSnap snapshots. The default COW cache size is set to 4096 MB or 5% of the volume size, whichever is greater. You can increase the COW cache size.

Replica Set Environments

• Replica sets must have at least one secondary node.

Sharded Cluster Environments

• The same database user must be created on all the sharded servers and on the config server.

• Each sharded server must be a replica set, and the replica set must have at least one secondary node.

• The Commvault software is not required on the arbiter node.
