eqlvolume show Command Syntax The command syntax is as follows: # eqlvolume show [--include mount-point | -i] [--exclude mount-point | -e] [--group-access-file file-location | -g] [--user-name user-name | -u] The following table describes the optional command parameters. Table 40. eqlvolume show Optional Command Parameters Parameter --include Abbr. -i Argument mount-point Description Specifies the mount points for which to display information. If not used, displays information on all mount points using EqualLogic volumes. --exclude -e mount-point Specifies the mount points for which information is not displayed. --group-access- -g file file-location Specifies the location of the group access file where the user names and encrypted passwords are kept. --user-name -u user-name If multiple user names have been stored in the group access file, specifies a particular user identity. If you are able to connect to the PS Series group and get information about the volume, the characteristics of each volume are also shown. The space used by each file system is calculated by subtracting the free space available from the total capacity. This number reflects the overhead created by each file systemʼs on-disk structures. The percentage used is calculated from the file system space used and the capacity. These numbers are not the same as those reported by the Linux disk free (df) utility. The minimum allocation sizes also differs. The file system layout determines whether space is actually needed on the array. For example, the file system reserves areas on the target for future on-disk structures and does not need to allocate space for those areas until they are written. The space used by the target volumes and the capacity are acquired from the PS Series array. These numbers will differ from the file system numbers because the file systems might have been built using a subset of the target space to leave room for expansion. Examples: Showing Mount Point Information This section includes examples of using the eqlvolume show command to show mount point information. The eqlvolume show command locates file systems, or mount points, that are supported by EqualLogic volumes to display the characteristics of the mount points and the volumes that support those mount points. Example 1: eqlvolume show Command This example shows the output of the eqlvolume show command with no options. In this output: • Mount point /lv11a is a thin-provisioned volume with replication enabled. Mount point /mnt/temp/lv11a is a temporary mount of a replica mounted by Auto Snapshot Manager (ASM). • Each mount point is represented in a single line above the volume name and group name of the EqualLogic volume used to support it. • Relationships are shown by grouping the mount points above the volume on the PS Series group. In this example, the LVM Logical Volumes /lv12a, /lv12b, and /lv12c are built from a single volume group that is built from one Physical Volume. The mount points are grouped above the volume vg12 on the PS Series group eqlgroup1. • Each mount point is shown with its file-system type and the mount attributes. # eqlvolume show File Systems File system or Volume Used Size Used% Type Attributes /lv11a 150 MB 9.84 GB 1.5% ext4 rw Managing Thin-Provisioned Volumes 101

eqlvolume show Command Syntax
The command syntax is as follows:
# eqlvolume show
[--include
mount-point
| -i]
[--exclude
mount-point
| -e]
[--group-access-file
file-location
| -g]
[--user-name
user-name
| -u]
The following table describes the optional command parameters.
Table 40. eqlvolume show Optional Command Parameters
Parameter
Abbr.
Argument
Description
--include
-i
mount-point
Specifies the mount points for which to display information. If not used,
displays information on all mount points using EqualLogic volumes.
--exclude
-e
mount-point
Specifies the mount points for which information is not displayed.
--group-access-
file
-g
file-location
Specifies the location of the group access file where the user names and
encrypted passwords are kept.
--user-name
-u
user-name
If multiple user names have been stored in the group access file, specifies
a particular user identity.
If you are able to connect to the PS Series group and get information about the volume, the characteristics of each volume are also
shown.
The space used by each file system is calculated by subtracting the free space available from the total capacity. This number reflects the
overhead created by each file system
ʼ
s on-disk structures. The percentage used is calculated from the file system space used and the
capacity. These numbers are not the same as those reported by the Linux disk free (df) utility.
The minimum allocation sizes also differs. The file system layout determines whether space is actually needed on the array. For example,
the file system reserves areas on the target for future on-disk structures and does not need to allocate space for those areas until they
are written.
The space used by the target volumes and the capacity are acquired from the PS Series array. These numbers will differ from the file
system numbers because the file systems might have been built using a subset of the target space to leave room for expansion.
Examples: Showing Mount Point Information
This section includes examples of using the
eqlvolume show
command to show mount point information.
The
eqlvolume show
command locates file systems, or mount points, that are supported by EqualLogic volumes to display the
characteristics of the mount points and the volumes that support those mount points.
Example 1: eqlvolume show Command
This example shows the output of the
eqlvolume show
command with no options. In this output:
Mount point
/lv11a
is a thin-provisioned volume with replication enabled. Mount point
/mnt/temp/lv11a
is a temporary mount of
a replica mounted by Auto Snapshot Manager (ASM).
Each mount point is represented in a single line above the volume name and group name of the EqualLogic volume used to support it.
Relationships are shown by grouping the mount points above the volume on the PS Series group. In this example, the LVM Logical
Volumes
/lv12a
,
/lv12b
, and
/lv12c
are built from a single volume group that is built from one Physical Volume. The mount
points are grouped above the volume
vg12
on the PS Series group
eqlgroup1
.
Each mount point is shown with its file-system type and the mount attributes.
