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

<SYNOPSIS>

sfcmount special|mount_point

sfcmount special mount_point

<DESCRIPTION>

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.

When mount processing goes wrong, error information is outputted to a console. Please perform management according to the outputted error information.

<NOTES>

• sfcfrmd daemon must be running to enable the execution of this command.
• The same set of the descriptions for special 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.
• Nodes outside the MDS positioning range alone cannot be mounted.
