B.2.1 sfcadd(1M) Adding a data partition

<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:

-D device[,device,...]

Specifies a partition that will be added as the file data area using a character special file. If multiple partitions are added, separate character special files by a comma.

<OPERANDS>

The following operands can be specified:

t_device

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>

<SEE ALSO>

fsck_sfcfs(1M), mkfs_sfcfs(1M), sfcadm(1M), sfcinfo(1M), sfcnode(1M).

<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).
