PRIMECLUSTER Global File Services Configuration and Administration Guide 4.1 (Linux)

9.2.3 Setting /etc/fstab

The GFS Shared File System required the description of entries to be mounted on /etc/fstab for all of the nodes that share the file system. Also, the description in the mount options field of /etc/fstab is used as the mount option when the mount command is executed. The mount options described in /etc/fstab for the same file system must be consistent on any nodes configuring the file system. Other than the mount option, noatrc can be specified in the mount options field. Specify the noatrc option when mounting is not to be performed when the node is started.

An example of setting /etc/fstab is shown below:

• When mounting in the rw mode on node startup:

  Parameter	Value
  special device	/dev/sfdsk/gfs/dsk/volume1
  mount point	/mnt/fs1
  filesystem type	sfcfs
  mount options	rw, noauto
  dump frequency	0
  Fsck pass	0

   

• when not mounting on node startup

  Parameter	Value
  special device	/dev/sfdsk/gfs/dsk/volume1
  mount point	/mnt/fs1
  filesystem type	sfcfs
  mount options	rw, noauto, noatrc
  dump frequency	0
  Fsck pass	0

   

[Table Mount options]

Option	Description
noatime	Does not update the file access time.
nosuid	A file system will be mounted with setuid execution permission. Note, however, that if nosuid is specified, mounting will be executed with setuid execution inhibited.
rw | ro	Mounts in read/write mode (rw) or read only mode (ro). By default, rw is used.
noauto	Required.
noatrc	Does not mount when a node is started. By default, mounting is performed when a node is started.

Be sure to specify noauto in the mount options field and 0(zero) in the dump frequency field and the fsck field.
