The clone split estimation helps you to estimate the required storage space (in MB) to split a volume clone. Depending on the clone split estimation provided by SnapDrive for UNIX, you can determine the space availability to split a volume clone.
-
Enter the following command to estimate the required storage space to split a volume clone.
snapdrive clone split estimate [-lun] long_lun_name [longlun_name…] | [{-dg | -vg | -fs | -hostvol | -lvol} _file_spe [file_spec…]] | [-snapname long_snap_name] {-volclone|-lunclone}] [-v | -verbose] [-dump | -dumpall]
This operation displays the following information:
-
Resource name
-
Container - Aggregate for a FlexClone
-
Required Space - space required to split the volume clone
-
Available space - space available on the container
-
Storage Status - indicates the space availability for a volume clone split
-
Owned Space - space occupied by the volume clone
-
Shared space - space occupied by the volume clone along with the parent
The
Owned Space
andShared Space
is displayed when you use-verbose
option. -
The following example estimates the storage space to split a volume clone.
# snapdrive clone split estimate -fs /mnt/my_mnt1 -fs /mnt/my_mnt2 Resource Container Required Available Storage Space(MB) Space(MB) Status /mnt/my_mnt1 f3050-220 400 61500 AVAILABLE -111:aggr0 /mnt/my_mnt2 f3050-220 3292 1129 NOT AVAILABLE -112:aggr1
For every file specification, SnapDrive for UNIX determines the required space that is available in the storage system to split a volume clone. Here, the /mnt/my_mnt1
file specification has the required space to split, and thus the storage status displays as AVAILABLE. Whereas, the /mnt/my_mnt2
file specification does not have the required space to split, and so the storage status displays as NOT AVAILABLE.
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 32365 403 403 55875 AVAILABLE -111:aggr0
