Abstract
At least two replicated instances of a source volume are split while allowing clients to access data moved during the split. Clients are redirected to the first replicated instance of the source volume. The first replicated instance is split by first moving files in a split path from the first replicated instance to the target volume. Then, after the files in the split path have been successfully moved to the target volume, a junction is inserted at the split directory to redirect clients to the target volume. After the first replicated instance is split, a second junction replaces the split path on the replicated instance of the first replicated instance.
