[aperi-dev] Checkin: to support the Oracle Cluster File System on Linux

["Robert Wipfel" <rawipfel@xxxxxxxxxx>]

Checkin

  ProbeLinux.java 1.8
  Filesystem.java 1.5

to support the Oracle Cluster File System (OCFS2) on Linux.

==

The Oracle Cluster File System (OCFS2) is an open source
cluster file system and project created and maintained by Oracle
and other Linux community participants. OCFS2 has a built-in
distributed lock manager (DLM), and cluster membership service,
though it can also be configured to accept cluster configuration
and membership events from userspace cluster managers (such
as LinuxHA) - it allows multiple SAN attached servers to mount
and share for concurrent access, the same file system. OCFS2 
was originally designed for database access to a shared cluster
file system, with requirements for direct I/O into large files. Recently
some Linux vendors have been using OCFS2 as a shared file
system for virtual machine hosting. OCFS2 will run in the domain
zero Linux kernel of the Xen hypervisor, where it provides a cluster
wide shared file system for SAN attached Virtual Machine hosts,
running virtual machines from OS image files stored in OCFS2.
