I installed two RHEL5 cluster nodes and it''s ok. The data is in storage at the filesystem that is gfs2. I can access the data from both nodes and cluster is ok. How can I access this data with my DomU machine? Could I configure direct access via physical device? Has anyone a document about this solution? ------------------------------------------------- Prof. Marcos Ferreira da Silva CST em Redes de Computadores Faculdade Ined - Uberlândia - MG (34) 3210-2106 / 3214-4131 www.faculdadeined.com.br _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
You can have a cluster of dom0 hosts, and you can also have a cluster of domU hosts. (We have both. Our dom0 cluster runs CLVM, and our domU cluster runs GFS.) However that by itself does not allow a dom0 and and domU to share storage, unless they are part of the same cluster. I haven''t tried to build a cluster of mixed physical/paravirt hosts, and I can imagine it would be tricky to do correctly. Alternatively, you could share the GFS2 filesystem with a domU over NFS.> -----Original Message----- > From: xen-users-bounces@lists.xensource.com [mailto:xen-users- > bounces@lists.xensource.com] On Behalf Of Marcos Silva > Sent: Wednesday, October 14, 2009 10:38 AM > To: xen-users@lists.xensource.com > Subject: [Xen-users] Xen and DomU GFS2 data access > > I installed two RHEL5 cluster nodes and it''s ok. > The data is in storage at the filesystem that is gfs2. > I can access the data from both nodes and cluster is ok. > How can I access this data with my DomU machine? > Could I configure direct access via physical device? > > Has anyone a document about this solution? > > ------------------------------------------------- > Prof. Marcos Ferreira da Silva > CST em Redes de Computadores > Faculdade Ined - Uberlândia - MG > (34) 3210-2106 / 3214-4131 > www.faculdadeined.com.br > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I''m trying to make a cluster between two DomU but they don''t connect. Maybe a multicast problem. Oct 15 13:36:48 localhost ccsd[2257]: Unable to connect to cluster infrastructure after 30 seconds. The DomU Interfaces have MULTICAST enabled. After I will try to put together this two nodes and the two Dom0 2009/10/14 Jeff Sturm <jeff.sturm@eprize.com>:> You can have a cluster of dom0 hosts, and you can also have a cluster of domU hosts.

It is used for control functions such as synchronizing cluster.conf. The ccsd needs to start, and connect, before the rest of the cluster daemons can start. Is there anything mentioning aisexec in /var/log/messages? Are the host names, or addresses, specified in cluster.conf reachable (i.e. with ping)? Have you made sure iptables is not running on the domU? -Jeff _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
