A facility to ignore inaccessible volumes for software defined storage deployed in container orchestrator systems is presented herein. An example method comprises, in response to receiving error message data representative of an inaccessibility of a volume of a group of volumes being used by a container in execution on application server equipment, sending indicator data to an agent process that is monitoring execution of the container, wherein the indicator data represents a first command of a collection of commands that orders the agent process to desist from mounting the volume of the group of volumes to an accessible global space, and based on a second command, mounting a partial group of volumes to the accessible global space, wherein the partial group of volumes excludes the volume that is inaccessible, and notifying the agent process that the partial group of volumes is available in the accessible global space.

Automatic deployment of software defined storage (SDS) executes bootstrap and site configuration generation phases. The bootstrap phase follows a command for nodes to start a bootstrap process with installation of prerequisite packages, and setting system parameters based on the discovered hardware. When the node is restarted, the required services are automatically started. When all of the expected storage nodes have registered, the next phase of deployment can be executed to automatically generate the site configuration based on the inventory of nodes and storage devices discovered during the bootstrap phase. A storage cluster is created that utilizes the storage resources previously discovered. A single command is used to create and start a storage cluster.
