[Linux-cluster] NFS HA

[Colin Simpson]

Nothing special

In resources,

<ip address="10.1.5.10" monitor_link="0"/>
<fs device="/dev/cluvg00/lv00prj" force_fsck="1" force_unmount="1"
mountpoint="/mnt/projects" name="prjfs" nfslock="1" nfsrestart="1"
options="acl" quick_status="0" self_fence="0"/>
<nfsexport name="exportclunfsprj"/>
<nfsclient name="nfsdprj" options="rw" target="10.0.0.0/8"/>

Then a service,

<service autostart="1" domain="uxnfsb" exclusive="0" name="nfsdprojects"
nfslock="1" recovery="relocate">
  <ip ref="10.1.5.10"/>
   <fs ref="prjfs">
    <nfsexport ref="exportclunfsprj">
     <nfsclient ref="nfsdprj"/>
    </nfsexport>
   </fs>
  </ip>
</service>

Obviously you'll need to tune this for your use case.

So a floating service IP address. Client mount options are just
"rw,hard,intr", with a DNS name associated to this service IP address.



Thanks

Colin
