B.2. Creating an MD region
The procedure for creating a new MD region is very similar for all the different RAID levels. When using the EVMS GUI or Ncurses, first choose the Actions Create Region menu item. A list of region-managers will open, and each RAID level will appear as a separate plug-in in this list. Select the plug-in representing the desired RAID level. The next panel will list the objects available for creating a new RAID region. Select the desired objects to build the new region. If the selected RAID level does not support any additional options, then there are no more steps, and the region will be created. If the selected RAID level has extra creation options, the next panel will list those options. After selecting the options, the region will be created.
When using the CLI, use the following command to create a new region:
create:region,<plugin>={<option_name>=<value>[,<option_name>=<value>]*},
<object_name>[,<object_name>]*
For <plugin>, the available plug-in names are "MDLinearRegMgr," "MDRaid0RegMgr," "MDRaid1RegMgr," "MDRaid5RegMgr," and "MD Multipath." The available options are listed in the following sections. If no options are available or desired, simply leave the space blank between the curly braces.
The Linear-RAID and Multipath levels provide no extra options for creation. The remaining RAID levels provide the options listed below.
B.2.1. RAID-0 options
B.2.2. RAID-1 options
B.2.3. RAID-4/5 options
