5.3.3 Example Configuration for an NFS
Server
To set up the NFS server, three resources are needed: a file system resource, a drbd
resource, and a group of an NFS server and an IP address. The following subsection
shows you how to do it.
Setting Up a File System Resource
The
filesystem
resource is configured as an OCF primitive resource. It has the task
of mounting and unmounting a device to a directory on start and stop requests. In this
case, the device is
/dev/drbd0
and the directory to use as mount point is
/srv/
failover
. The file system used is
xfs
.
Use the following commands in the
crm
shell to configure a filesystem resource:
crm(live)# configure
crm(live)configure# primitive filesystem_resource \
ocf:heartbeat:Filesystem \
params device=/dev/drbd0 directory=/srv/failover fstype=xfs
Configuring drbd
Before starting with the drbd High Availability configuration, set up a
drbd
device
manually. Basically this is configuring drbd in
/etc/drbd.conf
and letting it syn-
chronize. The exact procedure for configuring drbd is described in the Storage Admin-
Configuring Cluster Resources From Command Line 63
