Re: [OSR-users] cannot install comoonics

[Mark H. <hla...@at...>]

Hi Patrick,

comoonics-cs is not needed any more. I'm sorry for the confusion. 
If you want to install a CentOS5.2 NFS sharedroot cluster, the following yum 
command is sufficient to install the required comoonics packages:

# yum install comoonics-bootimage comoonics-cdsl-py 
comoonics-bootimage-extras-nfs

Best Regards,

Mark

Re: [OSR-users] cannot install comoonics

[Patrick W. <pw...@em...>]

Okay, I've made some progress.  The dependency problem still exists,  
meaning the comoonics packages CAN NOT be installed via yum (yet).  I  
worked around the problem by downloading the neccessary packages  
manually, installing XML::DOM, XML::XQL and XML::XQL::DOM via "cpan",  
installing the comoonics-cs package with "rpm -Uhv --force comoonics- 
cs*.rpm" and the rest of the comoonics packages with just "rpm -Uhv  
*.rpm".

I'm trying to build an CentOS 5.2 based NFS based cluster to replace  
our old CentOS 4.x NFS clusters, but am having trouble understanding  
how this comoonics could possible work with NFS.  I thought you needed  
GFS (or some other cluster filesystem) to get CDSL support.  Does NFS  
actually have support for CDSL?  Are CDSLs handled somewhere else,  
above NFS?  Or does comoonics NFS support not use CDSLs for NFS based  
clusters?  If so, then how does that work?

Thanks

[OSR-users] cannot install comoonics

[Patrick W. <pw...@em...>]

Hi,

long time SSI user, first time comoonics user.  I've built a new  
CentOS 5.2 x86_64 VMware system, and am following the instructions  
found on opensharedroot.com, but am running into unresolved dependency  
problems when trying to install the comoonics packages via YUM.

For clarity, I'll post the whole yum session.

I've already tried running "cpan" and installing the three perl  
modules manually, but that doesn't satisfy comoonics-cs' RPM  
prerequisites.

How do you recommend I proceed?

Re: [OSR-users] What can Open-sharedroot be used for?

[Marc G. <gr...@at...>]

Hi,
let me put it this way.
The concept and the usage pattern of an open-sharedroot cluster can be 
described as follows (BTW we call the base technology the Diskless Shared 
Root Cluster; http://en.wikipedia.org/wiki/Diskless_Shared_Root_Cluster):

1. Give one or more node concurrent access to a shared storage. That can 
either be a cluster filesystem like GFS/OCFS2/GFS2(not yet) on top of "any" 
blocklevel protokoll like parallel SCSI/iSCSI/SCSI via Fibre Channel and the 
like or a distributed network filesystem like NFS.

2. Share any valuable data between all nodes. In this case the rootfilesystem 
is the focus.

3. Establish a collection of tools and design practices to build such a 
cluster (for example handle hostdependent files, initrd or build cluster 
applications)

If we transfer it to your setup (as far as I understand your setup) there 
should be not difference between a node and a sharedroot server. That means 
apache/php/mysql and any other application runs on any open-sharedroot 
node/server. It can run multiple times (if it is capable of being 
loadbalanced over multiple servers - like apache with php) or one time (if 
not - like mysql).

I hope that explains things a bit.

Regards Marc.

[OSR-users] What can Open-sharedroot be used for?

[<br...@wi...>]

Hi guys,



I'm new to SSI so I would like to know if I could use open-sharedroot for

the following:



Let's say I have an open-sharedroot server with apache, php, mysql, etc

running. So once I have a node booting from the openshared-root server,

would that node be able to use apache, mysql, php, since those applications

are running in the open-sharedroot server? Will that node be using its own

resources (cpu, RAM, etc) or will it be using the openshared-root server's

resources?



If open-sharedroot is not really used in that way, could guys let me know

what could I be using open-sharedroot for?



Thanks in advance!

[Mark H. <hla...@at...>]

Hi, 

A new version of the comoonics open sharedroot cluster software collection for 
RHEL5 has been released. The new release 4.4 has been tested with RHEL5.1 and 
RHEL5.2 and has successfully passed the ATIX quality assurance tests. The new 
release contains bug fixes and some major enhancements.

1. New Features

* Support for RHEL5.2 and compatibles
* Support for iSCSI storage as shared root device
* Support for dhcp configured cluster interconnects

2. New Releases

* Comoonics Desaster Recovery Solution
The comoonics desaster recovery solution is software that creates stand-alone

[OSR-users] Last and final official release candidate of the com.oonics open shared root cluster installation DVD is available (RC4)

[Marc G. <gr...@at...>]

Hello,
we are very happy to announce the availability of the last and final official 
release candidate of the com.oonics open shared root cluster installation DVD 
(RC4). 

The com.oonics open shared root cluster installation DVD allows the 
installation of a single node open shared root cluster with the use of 
anaconda, the well known installation software provided by Red Hat. After the 
installation, the open shared root cluster can be easily scaled up to more 
than hundred cluster nodes.

You can now download the open shared root installation DVD from 
www.open-sharedroot.org.

We are very interested in feetback. Please either file a bug or feature or 
post to the mailinglist (see www.open-sharedroot.org).

More details can be found here: 
http://open-sharedroot.org/news-archive/availability-of-rc4-of-the-com-oonics-version-of-anaconda

Note: The download isos are based on Centos5.1!
          RHEL5.1 versions will be provided on request.

Have fun testing it and let us know the what you're thinking.

Re: [OSR-users] [Ocfs2-users] Shared Root configuration

[Mark H. <hla...@at...>]

Hi,

you should have a look at the open-sharedroot project 
(http://www.open-sharedroot.org/) . The purpose of this project is to provide 
an open and flexible filesystem based single system image (SSI) layer for 
linux clusters.
Currently, GFS and NFS can be used as shared root filesystems. OCFS2 support 
will be added soon (as shared writable mmap support is available now :-) ). 
Keep checking for updates at http://www.open-sharedroot.org/news .

Hi all!

We have just released the preview channel for the open-sharedroot software for 
RHEL5.
With the open-sharedroot software package, you can build up a NFS or GFS based 
diskless sharedroot cluster with RHEL4 and RHEL5. It also contains a toolset  
to clone or backup entire diskless sharedroot clusters.

Open Sharedroot homepage:

[OSR-users] Help - Newbie

[Daniel E. L. <ep...@gm...>]

Hi,

I'm in the process of setting up a 2 nodes  ACTIVE/ACTIVE cluster  with RHE=
L
ES v4 + GFS + SAN.
Each of my nodes are RAID 1+ 0  and have regular  root tree, and share a SA=
N
storage. My goal is to get both nodes share the same root, so then I just
install my applications once, instead of doing it on both nodes.

I was pointed that open-sharedroot can help me do the job.

Can someone please give me a hind of where I start ?

Thank you very much,

Daniel
