BUT, does it work even if I make snapshot of LV used by XEN? If not, I guess it should not be that hard to fix, I guess we just need to notify domU kernel to call needed VFS function to put fs into consistent state prior to creating snapshot. Can somebody comment on it, eventually correct me if I'm wrong? thanks a lot in advance regards nik --
