_______________________________________________________________________________Lab 5 – Create Fi le SetsLab 5 – Create Fi le Sets

In most file systems, a file hierarchy is represented as a series of directories that form a tree-like structure. Each directory contains other directories, files, or other file-system objects suchas symbolic links and hard links. Every file system object has a name associated with it, and is represented in the namespace as a node of the tree.

In addition, the IBM General Parallel File System(GPFS™) utilizes a file system object called a file set. A file set is a subtree of a file system namespace that in many respects behaves like an independent file system. File sets provide a means of partitioning the file system to allow administrative operations at a finer granularity than the entire file system:

• File sets can be used to define quotas on both data blocks and inodes.• The owning file set is an attribute of each file and can be specified in a policy to control

initial data placement, migration, and replication of the file's data.

When the file system is created, only one file set, called the root file set, exists. It contains the root directory as well as any system files such as quota files. As new files and directories are created, they automatically become part of the parent directory's file set. The file set to which a file belongs is largely transparent for ordinary file access, but the containing file set can be displayed along with the other attributes of each file using the lsfset command from the CLI.

____1. Hover the cursor over the third icon (Files) on the left, and click on File Sets to display the File Set panel.

For each file system, a root file set is automatically created when the file system is created. Notice that the path of the root file set is always linked to the mounting point of the file system. An administrator can define additional file sets.

There are two types of file sets: dependent and independent. A file set can be either dependent or independent, but not both simultaneously. An independent file set has a separate inode space, but shares physical storage with the remainder of the file system. The maximum number and pre-allocation of inodes for an independent file setcan be specified during file set creation, similar in concept to the way that the maximum number and pre-allocation of inodes for a file system are specified during file system creation. Any number of dependent file sets can reside within an independent file set. Independent file sets have all of the capabilities of a dependent file set. Independent file sets can have snapshots, whereas dependent file sets cannot.



___________________________________________________________________________________2. Click on New File Set button to add a new file set. Click on Custom

On the top of the New File Set panel, there are two icons: Basic and Custom. The Basic template can be used to create a dependent or independent file set and define its associated directory name. Using the Custom template, an administrator can create a new independent file set and configure quota and snapshot for the new file set in one operation. For dependent file set, an administrator can configure quotas using the custom template.

____3. Click on Browse … Select team# which is the file system name under which this new file set will be added. Click OK.

____4. Enter share# (replace # with the team number) in the file set name field. Enter a comment if desired. Notice that the share name is appended to the mount point of the mount point of the file system (e.g. /ibm/team#) to create the directory name thatthis share is linked to as shown in the ‘Junction path’ field.

Specify v7u\admin# in the owner’s field (where # is your team #). v7u is the active directory domain name. admin# is the user name.

____5. Select Independent as the file set type.



_______________________________________________________________________________

____6. Click on the Quota Tab to display the quota option panel. Select Set a quota. Specify 100 GB as the soft limit and 150 GB as the hard limit.

____7. Click Summary tab to review the parameters you specified.

____8. Click OK to create the file set as specified.

____9. Review file set creation progress and click Close to close the progression window.

____10. After the file set is successfully created, you should see share# file set listed in the file set panel.

____11. In a production environment, you may have many file sets; you can specify a filter to display a subset of the file sets in the file system. Enter team# in the filter field on the right top corner. Notice that only the file sets with information containing verbage team# are now listed.

____12. Click Reset to clear the filter. Edge2013 19 © 2013 IBM Corporation


_______________________________________________________________________________Lab 6 – Configure SharesLab 6 – Configure Shares

Objective: In this exercise, you will learn how to create shares using Storwize V7000 UnifiedGUI.

A Share is a shared disk space accessible through the protocols specified during its creation.FTP, HTTP, CIFS, or NFS shares can all be created, provided the protocol is enabled for the system. Shares can only be created for data which is stored in the GPFS™ file system. The local file system of the Storwize V7000 Unified file modules content cannot be shared. The administrator can define a share for an existing directory. In this case, the directory will be exported without any changes (to ACLs or owner). If a non-existing directory path has been specified during the share creation process, the directory will be created with the user specified owner and a default ACL.

____1. From the navigation tree, expand Files -> click Shares

____2. Click on New Share button to add a new share. There are 3 templates for creating CIFS, NFS or a Custom Share. CIFS template can be use to create a CIFS share. NFS template is for creating an NFS share. The custom template is used to create ashare supporting multiple protocols (e.g. HTTP, FTP, CIFS, NFS, and/or SCP).

____3. Click Custom to create a share using the Custom template which enables you to define multiple protocols such as CIFS, NFS, and others for a share.

____4. Click on the Browse button next to the Path field on the Custom template to specify a path to be shared. A browse window is displayed. You may see a message about creating a new subdirectory. Click on the X to close the message. Click on the + sign in front of team# to display its subdirectory and select share# and click OK to select the share# subdirectory.



___________________________________________________________________________________5. Enter share# where # is your team number (e.g. share1) in the Share Name field.

The share name can be any name you choose. This is the CIFS file share name that users will specify to access the directory defined in the directory path.

____6. Enter v7u\admin# as the Owner.

In this case, v7u\admin# will be as the owner of the subdirectory. The owner of a share can use active directory security management tool(s) to configure access control for other users and groups after the share is created

____7. Select Activate share (option with a checkmark)

____8. Select HTTP, SCP, and FTP protocols. (option with a checkmark)

____9. Click CIFS tab to display the CIFS options panel.

____10. Select the Enable CIFS option. Select Hide objects that the user does not have read access to and Browseable by file system browser.



_______________________________________________________________________________

____11. Click on NFS tab.

____12. Enter * as the Client Name and de-select Read Only Access and Root squash.

When configuring the NFS, you can define access control based on the clients’ names. You may use wildcard, asterisks (*), when defining the client access. For example, if you want to permit all clients to be able to read and write to the shared directory, you can specify *. as the client name, and uncheck the read_only field.

Following are the parameters that you can define for each client definition that you add:

read-only: client can only read files but not write files.

root squash: By default, any file request made by user root on the client machine is treated as if it is made by user nobody on the server (Exactly which UID the request is mapped to depends on the UID of user "nobody" on the server, not the client.) If no_root_squash is selected, then root on the client machine will have the same level of access to the files on the system as root on the server. Note: For security reasons,root squash should be selected for most clients in a production environment.

____13. Click Summary tab to review the input parameters that you have specified.

____14. Click OK to create the share.

____15. Review the details in the task progression window will be displayed. Click Close when the task is completed.

____16. If the new share was successfully created, it will be listed in the shares panel. Noticethat under the type, file set is listed for the share#.

_______________________________________________________________________________Lab 13 – Placement and Migrat ion Pol iciesLab 13 – Placement and Migrat ion Pol icies

Objective: During this exercise, you will add a second storage pool to the file system createdin the earlier exercises and setup placement and migration policies for that file system.

The Storwize V7000 Unified provides a means to automate the management of files using policies and rules. Properly managing your files allows you to efficiently use and balance yourpremium and less expensive storage resources.

A policy is a set of rules that describes the life cycle of user data based on the file's attributes.The Storwize V7000 Unified supports file placement and management policies. When a file iscreated or restored, the placement policy determines the initial location of the file's data and assigns the file to a storage pool. All data written to that file will be placed in the assigned storage pool. The management policy determines file management operation such as migration and deletion.

Add a Storage Pool to a File System

A storage pool is a collection of NSDs (Network Shared Disks) with similar properties that aremanaged together as a group. Storage pools provide a means to partition the file system's storage for considerations such as to improved price-performance by matching the cost of storage to the value of the data. For example, within a Storwize V7000 Unified system, you may have SSD, SAS and NL-SAS disks. In this case, you can create different storage pools using different types of disks. The system pool should contain the highest performing disks such as SSD disks. The silver pool may use less expensive SAS storage. File system metadata is always stored in the system pool. Metadata is the data that describes the characteristics of the objects in a file system. For example, file inode information is considered metadata. Since metadata is accessed for all file operations, it is recommended that highest performance disks are used for the system storage pool

____1. Select the third icon, Files -> File Systems. Right Click on the team# and select Edit File System. Click on the green + sign to add another pool.

____2. For the silver pool, click on the pull down menu button under Disk Type and selectmdiskgrp1 disks. Use the slider to set 2.5GB as the size of the silver pool. NOTE: the silver pool is purposely given a very small size to demonstrate how file placement policy works.



_______________________________________________________________________________

____3. Click OK to add the silver pool. After the storage pool is added successfully, click Close to close the task progression window.

____4. Click on the + sign in front of the team# file system to display the storage pools in the file system. Click on the + sign in front of a pool to show the disks in the pool.

Define Migration and Placement Policies for a File System

____5. Select Files -> File Systems. Right Click on the team# and select Edit File System.

____6. Click on the Migration Policy tab. Select Enable file migration. Change the startand stop thresholds to 80 and 70% respectively.

Threshold migration maintains a specific level of free space in the system pool. Thespace monitor daemon checks space usage of the system pool regularly. When space usage reaches the high threshold (Start Threshold) that you set for the system pool, migration automatically sends eligible files to the silver pool. Migration stops once space usage reaches the stop threshold.

The placement policy defining the initial placement of newly created files and must be activated if you desire to put newly created files into storage pools other than the system pool.



_______________________________________________________________________________

____7. Click on the Placement Policy tab. Select Enable file placement. Under silver pool placement rules: Select Extension as the file attributes, IN as the operator and enter *.zip as the value. Select share# in the Apply to section. This rule will place all files with the extension of *.zip for the share# file set in the silver pool.

____8. Click on the Policy Text tab to review policy rules that were created based on the input you specified in the two previous steps. Notice that there is an Edit button that you can click to enable you to edit the policy rules in a freelance manner. PLEASE DO NOT click on the Edit button because this will disable the templates

____9. Click on Summary tab to review all the parameters that you have specified for this file system.

____10. Click OK. After the file system is successfully modified, click Close to close the task window.
