<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have HP cluster consisting of two nodes
using as filesystem space two I-scsi servers.</FONT></DIV>
<DIV>There are two packages: one production pkg , one dev/test
pkg</DIV>
<DIV>
<DIV>So the prod pkg runs on server 1 and and the dev/test on server 2 and
in case of a failure everything goes to the node which survives.</DIV></DIV>
<DIV>There are two buildings each containing a node and a I-scsi server,
all servers and buildings are connected with gigabit. </DIV>
<DIV>The filsystems are mirrored on a host-based manner. ( =
importing iscsi disk and LVM/mirroring on top)</DIV>
<DIV> </DIV>
<DIV>So far so good, and I hope you get the picture.</DIV>
<DIV> </DIV>
<DIV>Now I want to implement this on a Redhat Cluster, and I have the four
servers setup, iscsi working, cluster up running but ...</DIV>
<DIV> </DIV>
<DIV>The questions now:</DIV>
<DIV>- Where does GFS in the picture ? Why should I use it ? Why not simple
create /dev/md and LVMs/ext3 and import them when needed. </DIV>
<DIV>- How do you implement multipathing in this picture ? I want redundancy on
my gigabit NIC's</DIV>
<DIV> </DIV>
<DIV>I missed the boat somewhere but please direct where I can find the light
for GFS and Multipathing in RedHat clusters.</DIV>
