I thought that the CX had some issues, but now I start to think that's a fault on the kernel side. If anybody is interested - as the buggy CX will be replaced, we're moving our production data to a different storage until we have the new machine. The old one will be used as additional disk-to-disk backup, but I can't see there any problems in testing/debugging stuff with it. At least I can put it under heavy load and see what will happen. Any ideas on that? Best regards, Bernd Zeimetz Darmstadt University of Technology -- dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
