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 | relatime | strictatime: Sets the method to update the last access time of a file.
If atime or relatime is specified, the last access time of a file is updated when the previous last access time is the same as or older than the last modify time or the last change time. Also, when the previous last access time of a file is old for over a day, it is updated.
If noatime is specified, the last access time of a file is not updated.
If strictatime is specified, the last access time of a file is updated for each file access.
The default is relatime.

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: Disallows a setuid execution. By default, allows setuid execution.
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.
Nodes outside the MDS positioning range alone cannot be mounted.
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.
