Command Reference A-73
To delete a qtree, remove it from a client as you would any directory. You can cre-
ate up to 254 qtrees on a filer.
The qtree security command changes the security style for files and directories.
Security style means the method the filer uses to determine whether a user has
access to a file. If
name
is the path name to a qtree, the security style applies to
the files and directories in the specified qtree. The path name to a qtree does not
need to end with a slash. If
name
is a path name to a volume, the security style
applies to those directories and files in qtree 0. Any new qtree you create inherits
the security style from qtree 0 by default. The path name to a volume must end
with a slash.
The security style can be one of the following values:
UNIX The user’s UID and GID, and the UNIX-style permission bits of the
file or directory determine user access. The filer uses the same
method for determining access for both NFS and CIFS requests. If
you change the security style of a qtree or a volume from ntfs to
UNIX, the filer disregards the Windows NT permissions that were
established when the qtree or volume used the ntfs security style.
ntfs For CIFS requests, Windows NT permissions determine user
access. For NFS requests, the filer generates and stores a set of
UNIX-style permission bits that are at least as restrictive as the
Windows NT permissions. The filer grants NFS access only if the
UNIX-style permission bits allow the user access.
If you change the security style of a qtree or a volume from UNIX to
ntfs, files created before the change do not have Windows NT per-
missions. For these files, the filer uses only the UNIX-style
permission bits to determine access.
mixed Some files in the qtree or volume have the UNIX security style, and
some have the ntfs security style. A file’s security style depends on
whether the permission was last set from CIFS or NFS. For exam-
ple, if a file currently uses the UNIX security style and a CIFS user
sends a set-ACL request to the file, the file’s security style is
changed to ntfs. If a file currently uses the ntfs style and an NFS
user sends a set-permission request to the file, the file’s security
style is changed to UNIX.
If you do not specify UNIX, ntfs, or mixed in the qtree security command, the
security style for
name
is displayed. If you omit
name
, the security styles for all
qtrees on the filer are displayed.
The qtree oplocks command enables or disables oplocks for files and directories
in a qtree or in a volume. If
name
is the path name to a qtree, the attribute applies
to files and directories in the specified qtree. The path name to a quota tree does
not need to end with a slash. If name is the path name to a volume, the attribute
applies to those files and directories in qtree 0. The path name to a volume must
end with a slash.
