I have a 3 node GFS cluster sharing 2 virtual IPs as 2 different
services. For some reason the failover is not working correctly. The
IPs are listed as services in the cluster.conf and the failover is set
to use ordered/restricted. Below is the pertinent cluster.conf parts.
The IPs failover when the box goes down but does not fail back to the
correctly prioritized box when it returns. I have included the error
from the log at the end. Thanks.
<failoverdomains>
<failoverdomain name="nfs_domain1" ordered="1"
restricted="1">
<failoverdomainnode name="fs101"
priority="1"/>
<failoverdomainnode name="fs102"
priority="2"/>
<failoverdomainnode name="fs103"
priority="3"/>
</failoverdomain>
<failoverdomain name="nfs_domain2" ordered="1"

<failoverdomainnode name="fs101"

<failoverdomainnode name="fs103"

</failoverdomain>
