Management partitions provide the important information for GFS Shared File System operation. Also, it is used for the "sfcfrmd" daemon to maintain data integrity. The management partition contains the following information:
Information of each node constituting the GFS Shared File System.
Information linking to a shared node and a shared device in each GFS Shared File System.
MDS and AC allocation information for each GFS Shared File System.
The node information of 1 must be set up using sfcsetup(8). The information of 2 and 3 can be set up, modified and added with sfcmkfs(8), sfcadm(8), sfcnode(8) and sfcadd(8). The sfcgetconf(8) command is available for backing-up the information within the management partition.
