Hi xeners, I am trying to have 2 DomU share a single Logical Volume. I need that at least one of the DomU has read-write access to the LV. I have tried, but up to now, it only works if both DomU have read-only writes to the LV. That''s a problem for me, because I wanted to set up Nginx on a DomU, and Rails on another one, and have Nginx get read access to an LV that would hold the public folder of the Rails app for serving static content. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Javier, You are right, I hadn''t thought about simple filesharing. Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I installed NFS on the server side, and here is the error message I get: Not starting NFS kernel daemon: no support in current kernel. I am running an Ovh KimsufiXL server with Debian Etch as Dom0 and Xen 3.2.1, each DomU runs a Debian Etch provided by Ovh. Is that an issue from my server distro? Can I fix it easily? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I have shutdown then recreated the DomU, but I still have the same problem. Is it because Ovh uses a homemade 2.6.21 kernel? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Have 2 DomU share a same Logical Volume
Perhaps your distro uses a kernel module to support NFS, rather than compiling it direct into the kernel? Perhaps NFS support is not installed by default (like Ubuntu-ish distros leave it out).

I am running Debian Etch Dom0 and DomU, and I think Debian doesn''t have NFA enabled by default. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I already tried according to the guide in your first link. But as Felix from Ovh mentionned, their shipped kernel doesn''t yet support the 20 years old technology NFS. I''ll have to roll my own kernel. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The Ubuntu kernel''s work after an apt-get install. Fedora came with it last I knew. NFS as a root file system I can understand is not enabled by default since there are known problems, but regular NFS support shouldn''t be such a problem. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
