Estimating the storage space to split a LUN clone

The clone split estimation helps you to estimate the required storage space (in MB) to split a LUN clone. Depending on the clone split estimation provided by SnapDrive for UNIX, you can determine the space availability to split a LUN clone.

Step

  1. Enter the following command to estimate the required storage space to split a LUN clone. snapdrive clone split estimate [-lun]long_lun_name [long_lun_name...] | [{-dg | -vg | -fs | -hostvol | -lvol}file_spec [file_spec...]] | [-snapname long_snap_name] {-volclone|-lunclone}] [-v | -verbose]
    This operation displays the following information:
    • Resource name
    • Container- Volume for a LUN clone
    • Required Space - space required to split a LUN clone
    • Available space - space available on the container
    • Storage Status - indicates the space availability for a LUN clone split
    • Owned Space - space occupied by the LUN clone
    • Shared Space - space occupied by the LUN clone along with the parent

    The Owned Space and Shared Space is displayed when you use -verbose option.

Example

The following example estimates the storage space to split a LUN clone.
# snapdrive clone split estimate -fs /mnt/my_mnt1
Resource     Container Required Available Storage 
                       Space(MB)Space(MB) Status
/mnt/my_mnt1 f3050-220  5120    9986    AVAILABLE          
             -112:/vol/vol_1

The following is an example of using the -verbose option. Alternatively, you can use -v option.

# snapdrive clone split estimate -fs /mnt/my_mnt1 -verbose
Resource    Container  Owned    Shared   Required Available Storage 
                       Space(MB)Space(MB)Space(MB)Space(MB) Status
/mnt/my_mnt1 f3050-220  365   403      5120     9986 AVAILABLE                  
             -112:/vol/vol_1
