Storage requirements for a single node cluster
A primary disk that has a 300 GB partition (sda) is used for the Bare Metal Orchestrator application operation and for internal storage.
The following shows an example of a storage partition mounted on a Global Controller node for single cluster deployments. The first partition (sda1) is required. However, your particular implementation of other partitions on sda may vary from this example.
Storage requirements for a high availability cluster
Three disks with mounted partitions must be configured on the Global Controller (CP1) and the two redundant high availability (HA) nodes (CP2 and CP3).
Matching disks and mounted partition assignments must be configured on all three nodes in the HA cluster.
The following shows an example of the storage partitions. The first partition (sda1) on the primary disk is required. However, your particular implementation of other partitions on sda may vary from this example.
The primary disk has a 300 GB partition (sda) that is used for the Bare Metal Orchestrator application operation.
The secondary disk has a 500 GB, non-boot partition (sdb) that is used for internal distributed storage. You can use either an ext4 deb-based file system (for example, Debian and Ubuntu) or an XFS rpm-based file system (for example, Red Hat Enterprise Linux and CentOS) for the secondary disk.
The secondary disk must be mounted on the file system. The storage mount path attribute storage_mount_path
is provided in the all.yaml file. For instructions, see Configure distributed storage.
