ocfs2-tools 1.8.4-3ubuntu3 (s390x binary) in ubuntu zesty

 OCFS2 is a general purpose cluster filesystem. Unlike the initial release
 of OCFS, which supported only Oracle database workloads, OCFS2 provides
 full support as a general purpose filesystem. OCFS2 is a complete rewrite
 of the previous version, designed to work as a seamless addition to the
 Linux kernel.
 .
 This package installs the tools to manage the OCFS2 filesystem, including mkfs,
 tunefs, fsck, debugfs, and the utilities to control the O2CB clustering stack.
