Operations

Tasks you carry out on a cluster that already runs, sorted by the task you have rather than by the component that the task touches.

Using the file system covers the everyday work on a mounted share: trash, snapshots, and the mfs* tools that need no administrator rights. Access control covers who may mount what and with which rights. Client and mount tasks covers the administrator's work on the mounts themselves and on the sessions they leave behind. Data placement tasks describes how to use storage classes, labels, and patterns to control where data is stored. Space management covers reading and managing what the cluster holds. Disks and Chunkservers covers the planned adding, draining, and removing of both. Master Server operations lists the tasks related to metadata and, in PRO, the tasks that involve more than one Master Server. Addresses and ports covers moving a running cluster to different addresses and ports. Multi-site operations covers clusters divided into locations PRO (PRO Edition only). Block device operations covers block devices served by mfsbdev.

Nothing in the cluster schedules any of this work for you. The cluster also keeps no record that a check was made. What to watch lists the readings to check on a running cluster and how often to check each of them. Your own operating and security policy decides who performs those checks, from which account, and what is kept as evidence afterwards. MooseFS does not set any of this.

Reference covers what an option is called and what value it accepts. How It Works covers why a mechanism behaves the way it does.
