===== Problem Description: =====
After a reboot of a Linux AhsayCBS server the AhsayCBS NFS service is not automatically starting up. It has to be started up manually using the **%CBS_INSTALL%/nfs/bin/startup.sh** script.

===== Cause: =====
The AhsayCBS NFS service symlinks in /etc/rc.d/rc2.d/ .... /etc/rc.d/rc5.d/ are broken or not created for the current runlevel 2 to 5.

===== Resolution: =====
To resolve this issue, please re-install the AhsayCBS NFS service.

Assumption: **%CBS_INSTALL%** = /usr/local/cbs 

**Note:** The following example is based on a CentOS 6.4 (Final) installation.

1. Login to AhsayCBS server as root.

2. cd /usr/local/cbs/nfs/bin

3. Run the following script to uninstall the NFS service: sh uninstall.sh

5. Verify the symlinks have been created for runlevel 2 to 5.
<code>
# ls -la /etc/rc.d/rc[2-5].d/*cbsnfs*
lrwxrwxrwx 1 root root 18 Mar 15 15:28 /etc/rc.d/rc2.d/S99cbsnfs -> /etc/init.d/cbsnfs
lrwxrwxrwx 1 root root 18 Mar 15 15:28 /etc/rc.d/rc3.d/S99cbsnfs -> /etc/init.d/cbsnfs

#</code>

6. Verify the AhsayCBS NFS service is running and listening to port 111
