Abstract
A request is received to copy a file from a source to a destination, the source being associated with a source inode, and the destination being associated with a destination inode. The source and destination inodes are sorted into a sorted order according to inode numbers identifying the source and destination inodes. Based on the sorted order, rename locks are acquired on the source and destination inodes. Based on the sorted order, inode locks are acquired on the source and destination inodes. After the rename and inode locks have been acquired, chunk map entries of the source inode are copied as entries of the destination inode to fulfill the request.
