CLI Reference for Mountpath (disk) management

This section lists mountpath management operations the AIS CLI, with ais mountpath.

A mountpath is a single disk or a volume (a RAID) formatted with a local filesystem of choice, and a local directory that AIS utilizes to store user data and AIS metadata. A mountpath can be disabled and (re)enabled, automatically or administratively, at any point during runtime. In a given cluster, a total number of mountpaths would normally compute as a direct product of (number of storage targets) x (number of disks in each target).
