NAME
qtree - create and manage qtrees
SYNOPSIS
qtree
qtree create [
name
]
qtree security [ name [ UNIX | ntfs | mixed ] ]
qtree oplocks [
name
[ enable | disable ] ]
DESCRIPTION
The qtree command creates qtrees and specifies attributes for qtrees.
A qtree can be an entire volume or a subset of a volume. It is similar to a partition
in that you cannot move files into or out of a qtree. There are, however, two dif-
ferences between a qtree and a partition:
A qtree is more flexible than a partition because you can change the size of a
qtree at any time.
A qtree enables you to apply attributes such as oplocks and security style to
a subset of files and directories rather than to an entire volume.
If there are files and directories in a volume that do not belong to any qtrees you
create, the filer considers them to be in qtree 0. Qtree 0 can take on the same
types of attributes as any other qtrees.
You can use any qtree command whether or not quotas are enabled on your filer.
The qtree command without any arguments displays the attributes of all quota
trees on the filer.
The qtree create command creates a qtree. It is equivalent to the quota qtree
command. If
name
does not begin with a slash (/), the qtree is created in the root
volume. To create a qtree in a particular volume, specify
name
in this format: /vol/
vol
_
name
/
qtree
_
name
.
A qtree can be created only in the root directory of a volume. By default, a qtree
has the same security style as the root directory of the volume and oplocks are
enabled. The root directory of a volume, by default, uses the UNIX security style.
A qtree does not have any restrictions on disk space or the number of files. To
impose these restrictions on a qtree, edit the /etc/quotas file. Refer to the quo-
tas man page for more information about the file format. To make the changes to
the /etc/quotas file go into effect, use the quota command. Refer to the quota
man page for more information about the quota command.
If you enter the qtree create command without arguments, the command dis-
plays all existing qtrees and their attributes.
