Split a cloned volume

Split a clone FlexVol volume from its parent volume to make the clone a normal read-write FlexVol volume.

Data is accessible on the clone and the parent during the split. The split process only updates metadata and requires minimal IO. No data blocks are copied.

About this task

The clone splitting operation involves the following:

  • New snapshot copies of the FlexClone volume cannot be created during the split operation.

  • A FlexClone volume cannot be split from the parent volume if it belongs to a data protection relationship.

  • If you take the FlexClone volume offline while splitting is in progress, the split operation is suspended; when you bring the FlexClone volume back online, the splitting operation resumes.

  • After the split, both the parent FlexVol volume and the clone require the full space allocation determined by their volume guarantees.

  • After a FlexClone volume is split from its parent the two cannot be rejoined.

Before you begin

Consider the following before you split a cloned volume:

  • To split a cloned volume, you must associate a link. If you don't have an existing link, create a link. To associate a link in the file system, click Associate link under Account name. Once the link associates, return to this operation.

  • You must be a cluster administrator.

  • The FlexClone volume must be online when the split operation begins.

  • The parent volume must be online for the split to succeed.
