dCache Pools

dCache vitualizes storage across multple hosts. These hosts stores files in the files system of its nodes in a container structure called a pool. Pools must be configured in multiple places.

PoolManager Property Pool

The PoolManager is the core of dCache as it maps files via to dCache to the storage on disk and to which pool. All pools in dcache should be specified in the pool manager settings. An example of adding a pool to the pool manager is shown below.

psu create pool ford_1

Once pools are registered in the pool manager they can be added to a pgroup. This allows operations to be performed on one or more pools by dCache.
