Has anyone used gfs with xen before (eg two domains mounting a common storage area)? I''d like to do some testing but the kernel patches for gfs in debian won''t apply to 2.6.11, and I don''t want to go down the road of finding a patch that does work if I hear that gfs & xen don''t play well together.

It should work - also, I''d be surprised if people out there hadn''t tried this already. For testing purposes, you could try using an undebianised XenLinux kernel and the stock GFS patches. If it works, you can try to integrate it all nicely.

If it works, you can try to integrate it all nicely.I never use debianized kernel source. Hate it with a passion(don''t get me started). I''ve always used pristine kernel source, and applied the xen patch myself. Applying gfs should be no different. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Applying gfs should be no different.I use make-kpkg nowadays, but I guess that''s just because I''m comfortable with it, and the resulting deb can be applied to multiple machines. The latest gfs I could find (redhat cvs) appears to be external modules, not patches to the kernel. My first attempt at compiling (./configure ; make ) didn''t work though.

Works fine, except the Dell PowerVault 660F that I''m using hangs up under heavy simultaneous I/O for some reason. Still trying to figure that one out with Dell.. if anyone''s got any ideas on that, I''d love to hear them! :) ------------------------------------------------------------------------ | nate carlson | natecars@natecarlson.com | http://www.natecarlson.com | | depriving some poor village of its idiot since 1981 | ------------------------------------------------------------------------ _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Basically, I patched a kernel by hand with the FC4 source, and built both the dom0 and domU kernels via make-kpkg. I then built the GFS modules the hard way (went to the source dir, ran ARCH=xen ./configure --kernel_src=/path/to/kernel/src, ran make, and copied *ko over to the Xen session), and installed it all. I had to use multicast networking; if I used the standard methods, the nodes would get removed right away. With Multicast, things work great. ------------------------------------------------------------------------ | nate carlson | natecars@natecarlson.com | http://www.natecarlson.com | | depriving some poor village of its idiot since 1981 | ------------------------------------------------------------------------ _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
