MODULE-7-STORAGE SPACE MANAGEMENT

This lab is all about how space is consumed when aggregates,volumes and files are created is essential for all storage administrator.

In this module, these are the tasks to be accomplished.

  • Explore volume space consumption.
  • Explore file space consumption.
  • Configure deduplication for a volume.
  • Create and manage Quotas.
  • Generate a quota report.
  • Modify the /etc/quotas file and implement quota changes.

 

The quota is basically limit set by the system administrator that restricts  certain aspects of file system usage on the modern operating system.The function of using disk quotas is to allocate limited disk space in a reasonable way.

EXPLORE VOLUME SPACE CONSUMPTION.

here we have to create an aggregate here is the screen shot of the aggregate that has been created

Create 32-bit RAID4 aggregate called aggr3 and check its available space from CLI.

Screenshot (2036)

 

these are the aggregates i have created

 

Screenshot (442)

Now we have to  create  a volume in aggr2  with named FULLvol.

Now we have to create a  volume in aggr3 named THINvol and  analyse the result in aggr3 and Thin vol.

EXPLORE FILE SPACE CONSUMPTION.

In this, step we have to create 30 MB volume in aggr from CLI using vol create Filevol -s file aggr3 30m and the analyse the result in the aggr2

CONFIGURE DEDUPLICATION

First we have to , license the deduplication service on your storage system and turn the service on.After that configure the deduplication service on NASvol to run on flexible volume and start the deduplication process for existing data and also check the space saving use.

Node1> df -s /vol/NASvol

CREATE AND MANAGE QUOTAS.

In this task we have  to  create Qtree in the Netapp storage manager with following details.

  • Name-nas_tree1
  • volume type-NASvol
  • select enable oplocks
  • select NTFS securit

Now we have to  create  a CIFS share for the tree we have made .In Netapp storage manager select share and create a share.

After this  in the  Netapp storage system create Quotas and select the NAS vol for the Quotas and on the Quota limits page enter the following values.

we have to set the disk spaces as per these things

  • Disk space hard limit
  • Disk space soft limit
  • Threshold
  • File hard limit
  • File soft limit
  • after this task has been completed we have to create a quota report

Create Quota report.

From the CLI enter quota report after that from the Netapp, storage manager selects the Quota and compare the details with the CLI report.

after this completion we have to

Modify the etc/Quotas file and implement Quota change.

 

conclusion:

this is the  module related to the  storage space management , this gives complete knowledge about the space allocations and managing the various space resources

this module is associated with the creation of the aggregate and adding over the volumes
