<SYNOPSIS>
sfcadd -D device[,device,...] t_device
<DESCRIPTION>
The sfcadd command adds file data partitions to the GFS Shared File System that includes a representative partition using the t_device operand. The file data partition of the file system can be added only if the file system is unmounted status. No data has to be saved or restored.
<OPTIONS>
The following options can be specified:
Specifies a partition that will be added as the file data area using a path name of the block special file. If multiple partitions are added, separate path name of the block special file by a comma.
<EXAMPLES>
When a representative partition adds /dev/sfdsk/gfs01/dsk/volume02 and /dev/sfdsk/gfs01/dsk/volume03 to the existing GFS Shared File System (/dev/sfdsk/gfs01/dsk/volume01).
# sfcadd -D /dev/sfdsk/gfs01/dsk/volume02,/dev/sfdsk/gfs01/dsk/volume03 /dev/sfdsk/gfs01/dsk/volume01 <Enter> |
<OPERANDS>
The following operands can be specified:
Specifies a path of a path name of the block special file of a representative partition of the GFS Shared File System.

<NOTES>
To expand a file system, all the nodes that share the file system must be active because information of each node is required.
sfcadd cannot add a partition if the total number of partitions including the additional partition exceeds the maximum number of partitions (maxvol) defined with sfcmkfs(8). When file data region size after adding partition exceeds the maximum file data region size specified by sfcmkfs(8) (-o maxdsz=n), a part of free area in file data region might not be able to be used because of management region shortage.
To execute sfcadd, the file system must be normal. If it is not, the message "file system (partition_name) is corrupted. To Fix: sfcfsck partition_name" will be output. Execute sfcadd again after recovering the file system using sfcfsck(8).
