Date: Oct 08
Product & Version: NVR 5.6.1
OS Version: CentOS 5.2 (not supported at the time of writing this article)
Module & Version: n/a
Application version: n/a


Symptoms:
Upgrade from NVR 5.1 to NVR 5.6 results in replication service not starting as kernel module can't be inserted:

[root@srv-lnx17 lib]# /etc/rc.d/init.d/nvr_replicator restart
Unable to open /dev/nvr : No such file or directory
NetVault:Replicator software version = 5.6.163
Customer license VALID.

Deleting the /usr/netvault/replicator/lib/nvr_dr.o file to have it rebuilt results in the same error.

The following modification have to be made to resolve this problem:

[root@srv-lnx17 4.x]# diff /usr/netvault/replicator/lib/build/4.x/cd_os_structures.c /usr/netvault/replicator/lib/build/4.x/cd_os_structures.c.orig
89c89
#include


The module can now be built and service is starting prope
