FlexClone

FlexClone

  1. Its license futures in NetApp.
  2. Flexclone is used for testing purpose. 
  3. Flexclone need volume snapshot, using that snapshot we can clone that to new volume.
  4. FlexClone volumes always exist in the same aggregate as parent volumes.
  5. Clone is in writable copy and without using a lot of disk space. After split the clone that time only clone will take space from the Aggregate.
Commands :

To Create new clone

     fas3070> vol clone create old_vol_name –b new_volume_name snapshot_name

To view clone status

     fas3070>  vol status new_volume_name

To start a clone split:

     fas3070> vol clone split start volname

To stop a clone split:

     fas3070> vol clone split stop

To check the status of a clone split:

     fas3070>  vol clone split status [volname]

To estimate the time of completion:

    fas3070>  vol clone split estimate [volname]

NDMP Copy

1 NDMP Copy

Transfers directory trees between filers using NDMP (Network Data management Protocol)
  • Ndmpcopy transfers data between filers/v-filers using the Network Data Management Protocol (NDMP) versions 3 and higher. 
  • This process can be thought of as creating a dedicated data pipe between dump running on the source filer and restore running on the destination filer.

1.1 Pre-Requisite

Turn on ndmp by

Filer > ndmpd on

Ping the filers each other and make sure they are reachable

Make sure that the Data ONTAP release on the filers you are using for the copy support NDMP version 3 and/or higher.

Filer >ndmpd version 

For filers running ONTAP version 7.X, change the ndmpd authentication type to challenge

Filer > options ndmpd.authtype challenge

1.2 How to run ndmpcopy command

From the filer use the following syntax to run the command.

Syntax:

ndmpcopy [options] source destination

Where, source and destination are of the form [filer:]path

Options:

-sa username:password This is used for authenticating at source filer

-da username:password This is used for authenticating at source filer

-st text | md5 Source filer authentication type

-dt text | md5 Destination filer authentication type

-l 0 | 1 | 2 Level 0,1 and 2 copy (default is 0)

-d Debug

-f Force flag

-h Help

Example:

Filer > ndmpcopy -sa root:password –da root:password  /vol/vol_s 10.100.201.10:/vol/vol_d

In this example /vol/vol_s directory on the source filer is copied to /vol/vol_d on filer 10.100.201.10

-sa root:password option is specified to user is root  and password is  “password” for the source user authentication and –da for the same purpose at destination filer, Screen shot.

1.3 Problems Faced and Lessons Learnt

  • Initially filer was giving ndmp authentication error, this was fixed by specifying the username and password (-sa and -da) option. 
  • NDMP can copy at qtree level, but can not copy individual sub directories 
  • Snapshot backups are taken for copying the data and snapshot copy is deleted after transfer is over. 
  • No need to restrict the destination volume for copy. 
  • Also ONTAP version 7.x requires, ndmpd.authtype set to challenge
