[Linux-cluster] NFS clustering - how to use fsid= options for the exports

[Finnur Örn Guðmundsson - TM Software]

Hi,

 

I have setup a active-standby NFS cluster.

 

Everything is working like it should, except for one thing.

 

In HP ServiceGuard you use /etc/exports on each node in a active-standby cluster to manage exports, and there you can use the fsid=X for each filesystem you want to export (helps with stale nfs errors after a failover).

 

In RHCS i cannot seem to get the server to correctly use the options ...

 

Here is my service:

 

                <service autostart="1" domain="nfsdomain" name="nfs">

                        <nfsexport name="home1">

                                <nfsclient name="nfshome" options="rw,sync,fsid=150" path="/home" target="10.50.102.128/25"/>

                                <nfsclient name="nfsdata" options="rw,fsid=50,sync" path="/data" target="10.50.102.128/25"/>

                                <clusterfs ref="home"/>

                                <ip ref="10.10.10.10"/>

                                <clusterfs ref="data"/>

                        </nfsexport>

 

Would this not be the correct way ? Is there a other way to do this except for manually using /etc/exports and just have RHCS manage the IP address transfer beteween the nodes?

 

Kær kveðja / Best Regards,
