How Qtree works in netapp

What is Qtree:

A qtree is a logically defined file system that can exist as a special subdirectory
of the root directory within either a traditional volume or a FlexVol.

Qtree Grouping:

Security style
◆ Oplocks setting
◆ Quota limit
◆ Backup unit

Security style:

1. NTFS
2. UNIX
3. Mixed

1. NTFS

To use NTFS security, the storage system must be licensed for CIFS.
Exactly like Windows NT NTFS: Files and directories have Windows NT file-level
permission settings.

2. UNIX:

Exactly like UNIX; files and directories have UNIX permissions.

3. Mixed:

Both NTFS and UNIX security are allowed: A file or directory can have either Windows NT
permissions or UNIX permissions.The default security style of a file is the style most recently
used to set permissions on that file.

Creating new Qtree:

qtree create /vol/vol/qtree
Example:
qtree create /vol/new_vol/my_tree
Result: The qtree my_tree is created within the volume named
new_vol.

Note:

You can create up to 4,995 qtrees within one volume
qtree status new_vol –v

Assigning or changing security style:

qtree security [path {unix | ntfs | mixed}]

path is the path name of the qtree or volume.
Use unix for a UNIX qtree.
Use ntfs for an NTFS qtree.
Use mixed for a qtree with both UNIX and NTFS files

Example:
qtree security /vol/users/docs ntfs
