[Linux-cluster] Help setting up failoverdomain for 4 resources in a 4 nodes cluster



After reading some mails about GFS oddities for serving Maildir I
decided to split the whole-Maildir-data into 4 ext3 filesystems and use
4 floating IPs for communication with imap proxies.

So I have identified 4 services each one composed of a filesystem and a
virtual ip. My config sketch is like:

<cluster>
  ...
  <rm>
    <service name="mdir-part1-svc" autostart="1">
      <fs name="mdir-part1-fs" mountpoint="/mdir/part1"
          device="/dev/disk/by-id/dm-uuid-part1-mpath-......."
          options="noatime"/>
      <ip address="10.100.100.1"/>
    </service>

    <service name="mdir-part2-svc" ...
      ...
    </service>

    <service name="mdir-part3-svc" ...
      ...
    </service>

    <service name="mdir-part4-svc" ...
      ...
    </service>
  </rm
</cluster>

So I have mdir-part{1,2,3,4}-svc services and node{1,2,3,4} nodes. My
doubt is how to setup the failoverdomain stanzas so mdir-part1-svc will
be served using node1 preferably, mdir-part2-svc preferably on node2 and
so on.

Regards,
maykel
