The Linux Users' Group of Davis (LUGOD), will be holding a meeting on:
Monday
May 17, 2004
6:30pm - 9:00pm
The meeting will be held at our regular location:
Davis Public Library
315 East 14th Street
Davis, CA 95616
The topic will be:
Oracle Clustered Filesystem, version 2
presented by: Kurt Hackel, Senior Software Engineer, Oracle Corp.
The Oracle Clustered Filesystem was created at Oracle as a
replacement for raw disks in a clustered database environment, and was
later released for Linux under the GPL. The primary goal of version 1
of OCFS was to make the administration of Oracle Real Application
Cluster (RAC) databases much easier by providing a cluster aware
filesystem that would allow Oracle I/O rates to be at or above raw disk
speeds, in exchange for much reduced metadata performance. In designing
OCFS version 2, a primary goal was to drastically improve this metadata
performance in order to allow database and system administrators to put
both database files, as well as executable and configuration files on
one filesystem. By making significant changes to the journalling,
caching, I/O and locking code, OCFS version 2 is much closer to being a
general purpose clustered filesystem than its predecessor. In addition
to these changes, I will also discuss what additional enhancements can
be made going forward in the OCFS code, and propose some possible changes
to the Linux VFS based on what we have learned in OCFS version 2.
Kurt Hackel is a Senior Software Engineer with Oracle Corp. and
has been with the company since 1996. In 2000, he joined the New
Internet Computer development project, working on some small parts of
the user interface, as well as adding gnome-vfs support to the userfs
(userland filesystem) kernel module. The following year, he began
to port the Oracle Clustered Filesystem from Windows NT to Linux, and
has been involved in each major change to OCFS since.
