<SYNOPSIS>
sfcadd -D device[,device,...] t_device
<DESCRIPTION>
The sfcadd adds the file data partition to the GFS Shared File System having the representative partition which specified as t_device. 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 the path name of a character special file. If multiple partitions are added, separate the path name of character special files by a comma.
<OPERANDS>
The following operands can be specified:
Specifies a path of a character special file of a representative partition of the GFS Shared File System.
<EXAMPLES>
When a representative partition adds /dev/sfdsk/gfs01/rdsk/volume02 and /dev/sfdsk/gfs01/rdsk/volume03 to the existing GFS Shared File System (/dev/sfdsk/gfs01/rdsk/volume01).
# sfcadd -D /dev/sfdsk/gfs01/rdsk/volume02,/dev/sfdsk/gfs01/rdsk/volume03 /dev/sfdsk/gfs01/rdsk/volume01 <Enter> |

<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 (-o maxvol=n) defined with mkfs_sfcfs(1M). When file data region size after adding partition exceeds the maximum file data region size specified by mkfs_sfcfs(1M) (-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 status of the file system must be normal. If the file system status is abnormal, sfcadd outputs the following message:
file system (partition-name) is corrupted. To Fix fsck -F sfcfs partition-name |
Execute sfcadd again after recover the file system using fsck_sfcfs(1M).
