[Linux-cluster] GFS and Postgres

[mmiranda at americatel.com.sv]

Hi List,
Im using linux-ha with postgres, is the traditional active/passive cluster
where the services are failed over from one node to another, i mean the
service is  shuted down in one node and started up in the another, so far so
good, but i need an active/active configuration because the next year the
load in postgres with increase a lot (hundreds of additional transactions),
i couldnt find any pointer on using postgres with GFS, the hardware are two
HP DL380 and one HP MSA500 shared storage connected with a dual scsi
controller.
Is someone using a similar scenario?, if so , please share your
installation/configuration or comments with us, it will be greatly
appreciated,
Thanks 
Miguel
