Hi, I''m using xen on two-node redhat cluster (CVS devel version), using lvm as storage backend. redhat cluster is used to synchronize LVM metadata (using clvmd) and as storage for domain configs and dom-U kernels (with gfs). Latest version of redhat cluster works with xen-2.0.4, but not with xen-2.0-testing. ccsd failed to start on 2.0-testing. Anyone knows what the problem is? I assume most feature on 2.0-testing will eventually moved to 2.0-stable? I''m satisfied with the current confuration, and I was hoping that future versions of xen and redhat cluster will be able to coexist together.

Anyone knows what the problem is?I''ve no idea which changset is causing the problem. Perhaps you could use BK to do a ''binary chop'' to determine what the problematic one is?> I assume most feature on 2.0-testing will eventually moved to > 2.0-stable?Yes, it would be good to find out what the problem is before the 2.0.5 release.

The only other example with this I have seen is multipathd which just doesn''t run under xen, and even goes as far as segfaults gdb if you try to debug it.

Therefore, I don''t even have /lib/tls :) Anyway, it worked with xen-2.0.4, which is good, but I''m worried that if -testing becomes 2.0.5 it will stop working.

What does gdb tell you about the ccsd backtrace?

If it works. You''ll have shared storage for all the virtual domains, which means xm migrate should work nicely. It should work without clvmd, but I would have to reboot one node to synchronize LVM metadata each time I add new LV. And redhat cluster does not say it have to be run on redhat systems :)> What does gdb tell you about the ccsd backtrace? >Which output of bt do I need to post? all?
