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.
