Cluster Filesystem

Tonatiuh — Mon, 01 May 2006 00:42:47 GMT

Is there any native cluster filesystem for Red Hat Enterprise Linux 4?

Any other idea?

I have a shared storage and want to share a filesystem to store several kind of files.

Shalom,

Its called GFS.

It cost $500 to get it from Redhat.

It cost $0 to get it as part of Fedora Core 5 or Centos. Centos is binary compatible with RH Enterprise line.

There is also OCFS from Oracle, which may or may not be mature enough for your uses:

Freely downloadable, but currently only the functionality needed by Oracle is verified.

Steven:

Is that GFS a RPM I can install and format a partition whit it and share my info?

Can I install the Fedora GFS to Red Hat Enterprise Linux 4?

Matti:
The OCFS is a very mature Cluster Filesystem. I am currently using it in a production system, but it only can store Oracle datafiles. I cannot store files of other types in an OCFS (that is what I am trying to do).

GFS is a cluster-aware distributed filesystem, using the RH cluster manager as the distributed comms.

The FC5 versions won't do it for you, you want the CentOS 4 versions, as they are (as SEP said) binary compatable with RHEL.

AFAIK, OCFS2 is a general-purpose fs:

Oracle CFS is supports only oracle database files, you cannot use this file system for normal files. Use Red Hat's GFS instead.

"OCFS2 is the next generation of the Oracle Cluster File System for Linux. It is an extent based, POSIX compliant file system. Unlike the previous release (OCFS), OCFS2 is a general-purpose file system"

Thank you Vitaly for the update. It seems that you are right!

"OCFS2 is the next generation of the Oracle Cluster File System. It has been designed to be a general-purpose cluster file system. With it, one can store not only database related files on a shared disk, but also store Oracle binaries and configuration files (shared Oracle home) making management of RAC even easier."

It would worth a try!

Vitaly is RIGHT!

I was WRONG!

I will try with it.

Good luck!

Seems I have to update my knowledge on OCFS too. I haven't actually used OCFS but I knew it exists. Seems that there may actually be two versions of it, if Oracle refers specifically to both OCFS and OCFS2.

Live and learn, I guess...

Hi there.
Just one more point.
Unix ( Linux ) scripts might not work from ocfs disks.

Hi,

Is GFS fully supported by HP?

Thanks

I don't think HP support GFS individually(correct me if wrong)but GFS can co-work with MC/SG for linux. And hp support this configuration.
