- Select the source server and mirror volume
Chooses a volume of the meta disk.
The volume of the meta disk needs another seperate volume available to attach a drive letter. The followings need to be prepared for making such volume:
Drive letter
For example, M- Directory mount
For example, C:\vdrive - Volume's name in GUID format
For example, \\?\Volume{ed8a8f02-18b3-11e6-91b4-000c29ac57f8}\ - VHD (Virtual Hard Disk)
For example
1. m c:\r0_meta.vhd # VHD + format of drive letter
2. C:\vdrive c:\r0_meta.vhd # VHD + mounting format of a directory
3. \\?\Volume{ed8a8f02-18b3-11e6-91b4-000c29ac57f8}\ c:\r0_meta.vhd # VHD + GUID method
Note title 외부 메타 데이터 볼륨 A meta volume should be created with RAW status that the volume was not formatted, when creating a separate volume. WDRBD accesses to a meta volume as a sector unit basically, therefore, some part of a sector may not accessible because those are protected because of result from request for an authority to write against a boot record area if the volume has been formatted through the particular file system such as NTFS type. Moreover, it would not be able to use as a meta disk for WDRBD because a meta area of the file system such as MFT is made. So it is recommended choosing the option for what the volume is not formatted when creating the initial volume.
