Thank you for your reponses so far, it appears my interconnect could be
the issue, but first, I neglected to
mention one thing in my earlier email (which is included below), the
file I was trying to copy was
between two different raidsets that are located on a SAN (HSG80).
>From the information I have received this indicates that performance on
the SAN is impacted by
the speed of interconnect.
One thing I did not try is one raidset is owned by one member, and the
other raidset is owned by the other
member. A test for another day.
Now for my latest problem, I shutdown both members, changed the mode to
FastFD, boot the first member,
comes up just fine, boot the second member and I get
CNX MGR: cannot form : quorum disk is in use : "unable to establish
contact with member using disk"
switch back to twisted pair and everything works as advertised (except
for the copy part)
Is there some other configuration that I need to do ? I have searched
the Docs and I can't find anything.
Will definitely summarize once I get my 100full going !!
Thank you in advance
Darren

I am still in the process of building a test/dev 5.1a cluster with the
following configuration
1. A DS10 and a alphaserver 1200 as the members.
2. Both systems has the lastest firmware
3. The interconnect is ip-based and is running at 10mb half duplex.
The problem I am having is, a copy of a 200Mb file on one member takes 3
secs, while on the
second member, it can take upto 5 minutes.
It appears to be affected by who owns the drives, using cfsmgr -c to
determine. I have verified this
my moving the ownership around.
Has anybody else seen this problem, and if so what steps do I need to
make to rectify the problem.
Will summarize
Darren
