Disk and File System Management 3-7
The filer uses two naming conventions to indicate the root volume:
‡
/vol/vol0
‡
/
In the /vol/vol0 convention
‡
/vol
Indicates that the next part of the path, such as
vol0
in this example
,
is a volume
name.
‡
/vol0
Indicates the default name of the root volume for a filer. You can change this
name using the
vol rename
command.
Mounting volumes: On filers configured with multiple volumes, mounting
/
is equiv-
alent to mounting /vol/vol0/ , (where vol0 is the root directory of the root volume).
Paths that begin with
/
(for example,
/etc
) refer to directories on the root volume.
NOTE: /vol is not a directory—it is a special virtual root path under which the filer
mounts other directories. You cannot mount /vol to view all the volumes on the filer;
you must mount each filer volume separately.
In mount requests and server commands, prefix the path names of the volumes and
directories you want to mount using the convention
/vol/volume_name/directory
.
Example: For example, /vol/users/home/cheryl is a directory called /home/cheryl in a
volume named
users
.

Whether you should use the default single volume configuration or create additional
volumes depends mainly on the storage capacity of the filer.
Use of a single volume: If you want the filer to be configured with a single volume,
you do not need to do any further volume configuration after you complete the initial
setup.
If your filer doesn’t have a large number of disks, a single-volume configuration is
probably all you need. You can create additional volumes in the future.
Use of multiple volumes: There are several factors to consider before deciding to
create and use multiple volumes:
Configuring with multiple volumes aids in the administration of filers that have large
storage capacities, enabling you to
‡
Perform administrative and maintenance tasks, for example, backup and restore,
on individual volumes rather than on a single, large file system.
‡
Set
option
command values, for example,
snap sched
,
raidsize
,
minra
,
no_atime_update
, and so on, differently for individual volumes.
