File System Appears Empty After Instance Reboot

After a rebooting an instance, the file system appears empty.

Cause: The file system was not automatically remounted after the reboot.

More Information: The rpcbind and nfslock services don't automatically start at reboot by default.

Solution:

Add the file system to the instance /etc/fstab file, so the file system is automatically remounted after reboot.
1. See To auto-mount a file system for instructions.
Set the rpcbind and nfslock services to start automatically on every reboot.
1. Use the following commands to start the rpcbind and nfslock services:
```
$service rpcbind start
$service nfslock start
```
2. Verify that the rpcbind and nfslock services are running:
```
$service rpcbind status
$service nfslock status
```
3. Enable the services to start automatically at reboot:
```
$chkconfig rpcbind on
$chkconfig nfslock on
```
