B.1.4 sfcmount(8) Mount the GFS Shared File System on the local node

sfcmount device | mount_point
sfcmount device mount_point

The sfcmount command mounts the GFS Shared File System on the local node only. This command can be executed from any nodes that can access the GFS Shared File System.

During the mount processing, this command activates sfcfsd and, if necessary, MDS. Pre-defining /etc/fstab is necessary.

Only a super user can perform mount processing.

The following mount options can be specified for /etc/fstab. Multiple options must be delimited with commas.

atime | noatime: Mount in the manner of updating (atime) or not updating (noatime) the last access time of files.
The default is atime.

atrc | noatrc: Specifies whether to mount (atrc) or not to mount (noatrc) at the node startup.
The default is atrc.

async: Mounts in the manner of processing any I/O for the file system asynchronously.
The default is async.

defaults: Synonymous with rw, suid, dev, exec and async.

dev | nodev: Mounts making block special files available(dev) or unavailable(nodev).
The default is dev.

exec | noexec: Mounts giving permission(exec) or no permission(noexec) to execute binary files on the file system.
The default is exec.

rw | ro

Mounts the file system as read/write enabled(rw) or read only(ro).

The default is rw.

suid | nosuid: Mounts giving permission(suid) or no permission(nosuid) to execute setuid.
The default is suid.

The following operands can be specified:

device: Specifies path name of the block or character special file of a representative partition of the file system to be mounted.

mount_point: Specifies the name of the directory to be mounted.

# sfcmount /dev/sfdsk/gfs01/dsk/volume01 /mount_point <Enter>
# sfcmount /dev/sfdsk/gfs01/dsk/volume01 <Enter>
# sfcmount /mount_point <Enter>

<FILES>

/etc/mtab

Table for the currently mounted file system.

/etc/fstab

Environment file for the file system.

sfcumount(8), sfcmntgl(8), sfcumntgl(8)

mount(8) and fstab(5) in the online manual.

<NOTES>

sfcfrmd daemon must be running to enable the execution of this command.
After the GFS Shared File System is mounted on one or more MDS nodes, it should be mounted on a node which is not the MDS node. Or, the GFS Shared File System should be mounted at the same time on all nodes by using sfcmntgl(8). The GFS Shared File System cannot be mounted first on a node which is not the MDS node.
The same set of the descriptions for device and mount_point must be contained in /etc/fstab.
Mount processing is always performed using the mount options for the mount point described in /etc/fstab. When no mount options are described in /etc/fstab, mount processing without any options is performed.
