moving

any

expired

the

reclamation

function.

This

method

works

by

reclaiming

the

active

files

from

the

legacy

ACSLS

storage

pools.

Reclamation

processing,

however,

is

very

resource

intensive

and

should

be

performed

during

periods

of

little

activity

on

the

server.
