<p class=MsoPlainText>I’m going to be building a 6 node cluster with
blade servers that only have 2x network connections attached to EMC DMX
storage. The application we are running has it's own cluster layer so we won't
be using the failover services (they just want the filesystem to be visible to
all nodes). Each node should be reading/writing only in it's own directory
with a single filesystem size ~15TB.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Questions I have are this:<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText> 1) The documentation is unclear as to this, I'm
assuming that I should I bond the 2x interfaces rather than have one interface
for public and one for private. I'm thinking this will make the system much
more available in general, but I don't know if the public/private is a hard
requirement (or if what I'm thinking is even better) Best case would be to get
2x more but unfortunately I don't have that luxury. If this is preferred, would
I need to use 2x ip addresses in this configuration, or can I use just the 1x
per node.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText> 2) I have the capabilities to support scsi3
reservations inside the DMX, should I be using scsi3 instead of power based
fencing (or both). It seems like a relatively option, is it ready for use or
should it bake a bit longer. I've used Veritas VCS with scsi3 previously and it
was sometimes semi-annoying. But the reality is that availability and data
protection is more important than not being annoyed.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText> 3) Since I have more than 2x nodes should I use
qdiskd or not (or is it even needed in this type of configuration with no
failover); looking around it appears that it’s caused some problems in
the past.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText> 4) Any other tips for a first time GFS user<o:p></o:p></p>
