in my setup, hostnames are like node01xxx, e.g. node01c (crossover)
or node01i (internal).

because i'm not using a "-" between the hostname and the suffix,
i would change the master_host generation part to something like:
> master_host="${new_master_host}${OCF_RESKEY_replication_hostname_suffix}"
also, is there/should there be any implication of the suffix on
the log files, e.g.
> master_log_file=`$CRM_ATTR -n $new_master_host-log-file-${INSTANCE_ATTR_NAME}
> -q -G`
vs.

?
thanks for your contribution!
