22.2.3 Setting vfstab

In the GFS Shared File System, it is necessary to code an entry that is to be mounted on /etc/vfstab of all the nodes that share a file system. Also, the information that is specified for the mount options of /etc/vfstab are used as the mount option when the mount command is executed. Other than the mount option, noauto can be specified for the mount options. Specify the noauto option when mounting is not to be performed when the node is started.

Examples of /etc/vfstab entries are shown below:

• When mounting in rw mode at startup of the node:

  Parameter	Value
  device to mount	/dev/sfdsk/gfs/dsk/volume1
  device to fsck	/dev/sfdsk/gfs/rdsk/volume1
  mount point	/mnt/fs1
  FS type	sfcfs
  fsck pass	-
  mount at boot	no
  mount options	rw

• When mounting is not performed at startup of the node

  Parameter	Value
  device to mount	/dev/sfdsk/gfs/dsk/volume1
  device to fsck	/dev/sfdsk/gfs/rdsk/volume1
  mount point	/mnt/fs1
  FS type	sfcfs
  fsck pass	-
  mount at boot	no
  mount options	rw, noauto

[Table Mount options]

Option	Description
closesync	All non-updated data in the relevant file is reflected when the file is finally closed.
intr | nointr	Allows (intr) or prevents (nointr) a keyboard interruption to forcibly terminate a file operation queue process on the locked file system. intr is used as the default.
noatime	Does not update the file access time.
noforcedirectio | forcedirectio	Mounts a file system with a forcible direct I/O specification (forcedirectio) or with a non-forcible direct I/O specification (noforcedirectio). If forcedirectio is specified, access to the file system will be attempted with forcible direct I/O. If an access request does not satisfy the I/O requirements, normal access will be performed. Direct I/O refers to the direct data transmission of a file system between a user space and a disk, without passing through the data transmission buffer that is prepared in the kernel space. By default, normal access is performed with noforcedirectio.
nosuid	A file system will be mounted with setuid execution permission. Note, however, that if nosuid is specified, mounting will be executed with setid execution inhibited.
rw | ro	Mounts in read/write mode (rw) or read only mode (ro). By default, rw is used.
noauto	Does not mount when a node is started. By default, mounting is performed when a node is started.

Specify "-" to fsck pass and "no" to mount at boot.
