Claim 0:
1. A computer-implemented method for tape-to-tape copying between nodes on a Linear Tape File System using a cluster-wide named pipe, the computer-implemented method comprising:
transferring data, through a data path for storage, between a first node and a second node, wherein both the first node and the second node implement a parallel shared-disk file system through the data path for storage, wherein the data path for storage comprises node data reading and writing from a shared-disk and to the shared-disk, and wherein the transferring of data between the first node and the second node comprises:
writing, by the first node, the data for tape-to-tape copy from a first tape drive to the shared-disk; and
writing, by the second node, the data written from the shared-disk to a second tape drive, wherein writing the data from the shared-disk to the second tape drive comprises:
obtaining one or more head data blocks and head offset from metadata of a global first-in-first-out (gfifo) object; and
responsive to determining a requested data length for the one or more head data blocks is greater than zero, reading at least a portion of the data from a head offset of the one or more head data blocks.
