Upgrading the loopbacknfs POSIX Client on a Linux Server

This section describes how to upgrade the loopbacknfs POSIX Client on a Linux server.

To upgrade the loopbacknfs POSIX client on a RHEL, SUSE, or Ubuntu server, you must upgrade the mapr-loopbacknfs package.

Note: To migrate the POSIX Client to a FUSE-based POSIX client, see Migrating to FUSE-based POSIX Clients.

Stop the mapr-loopbacknfs service.
```
service mapr-loopbacknfs stop
```
Remove any currently installed client patches. For example:
- On RedHat / CentOS: yum remove mapr-patch-loopbacknfs
- On SUSE: zypper remove mapr-patch-loopbacknfs
- On Ubuntu: apt-get remove mapr-patch-loopbacknfs
Upgrade the mapr-loopbacknfs package.
- On RedHat / CentOS: yum update mapr-loopbacknfs
- On SUSE: zypper update mapr-loopbacknfs
- On Ubuntu: apt-get install mapr-loopbacknfs
Update the cluster configuration information in the mapr-loopbacknfs.new file.
```
vi /usr/local/mapr-loopbacknfs/initscripts/mapr-loopbacknfs.new
```

Copy mapr-loopbacknfs.new to the mapr-loopbacknfs script

cp
/usr/local/mapr-loopbacknfs/initscripts/mapr-loopbacknfs.new
/usr/local/mapr-loopbacknfs/initscripts/mapr-loopbacknfs

Start the loopbacknfs service.
```
service mapr-loopbacknfs start
```
Check the status of the loopbacknfs service.
```
service mapr-loopbacknfs status
```
