在图2中，用户Admin1、Admin2和Admin3均为逻辑卷管理员，在RBAC模式下可管理任其一个逻辑卷组(vg 1、vg 2或vg3)。
In Figure 2, users Admin1, Admin2 and Admin3 are logical volume administrators and are ideally designated to manage any of the logical volume groups (vg1, vg2 and vg3) in RBAC model.
然而，若要基于所需资源以粒度的方式限制管理员对逻辑卷的管理，可以将域分配给他们。
However to restrict management of logical volumes by administrators in granular fashion based on the required resources, domains can be assigned to them.
LVM系统确保逻辑卷在管理员物理地改变存储位置的同时能够继续正常操作。
The LVM system ensures that our logical volumes continue to operate perfectly while allowing the administrator to physically change where everything is stored.
