The Create command creates containers. The first argument in the Create command is the type of object to produce, in this case a container. The Create command then accepts the following arguments: the region manager to use along with any parameters it might need, and the segments or disks to create the container from. The command to complete the previous example is:
Create:Container,LvmRegMgr={name="Sample Container",pe_size=16MB},sdc,sdd,hdc
The previous example accepts the default values for all options you don't specify. To see the options for this command type:
query:plugins,plugin=LvmRegMgr,list options
