Possible to run iscsi-target and initiator on same server?
I am trying to install Oracle RAC in a two node cluster for testing
purposes, so performance is not something that concerns me. I just want
to go through the process all the way to creating a database. I have all
the prerequisites except the shared storage and thought I'd give this a
try.
I'm running:
- CentOS 5.3 kernel 2.6.18-164.el5
- iscsitarget-1.4.18-1

best practices in using shared storage for XEN Virtual Machines and auto-failover?
Hi all,
Can anyone pleas tell me what would be best practice to use shared
storage with virtual machines, especially when it involved high
availability / automated failover between 2 XEN servers?
i.e. if I setup 2x identical XEN servers, each with say 16GB RAM, 4x
1GB NIC''s, etc. Then I need the xen domU''s to auto failover between
the 2 servers if either goes down (hardware

xhr :get,:new
end

streaming server on a virtual machine.
I need to installa a streaming server for live videos and for video on demand.
My choice is red5.
Do you think I can use a xen virtual machine to run a streaming service?
Or it is better not to virtualize?
Sorry for my bad english.

how to optimize CentOS XEN dom0?
Hi,
I have a problematic CentOS XEN server and hope someone could point me
in the right direction to optimize it a bit.
The server runs on a Core2Quad 9300, with 8GB RAM (max motherboard can
take, 1U chassis) on an Intel motherboard with a 1TB SATA HDD.
dom0 is set to 512MB limit with a few small XEM VM''s running:

Drag and Drop with scriptaculous
Hello,
I''m making my first steps with prototype and scriptaculous.
I''m playing around with drag and drop.
What I try to do:
I have some Draggables and some Droppables. You can drag each
Draggables to each Droppables.
When I drop a Draggables I want to center the Draggables inside the
Droppable.
And here I get my first problems:-(
I use this code:

behavioural testing of puppet manifests with cucumber-puppet
Hi,
I''d like to announce a little tool I have written, called cucumber-
puppet. It supports writing behavioural tests for your puppet
manifest, using cucumber. This allows for BDD-style manifest
development and fearless refactorings.

Let me know what you think!

Best way to use iSCSI in domU
Hello,
We need to use iSCSI in some of our domUs. By the moment, iSCSI is not
for system filesystem, but for data filesystem.
I am wondering what is the best way to use it. Is it better to
configure it in dom0 and then attach the device to the domU? Or is it
better to configure it directly in the domU?
I am thinking that if we configure it in the dom0, then we can''t share
that iscsi

Deprecating the mocking framework?
I saw in one of Dave C.''s comments to a ticket that "our current plan
is to deprecate the mocking framework." I hadn''t heard anything about
that, but then again I haven''t paid super close attention to the list.
Are we planning on dumping the mock framework in favor of using Mocha
(or any other framework one might want to plug in?).

Many of my ( 30+ ) puppet installation freeze up after some time. The

slow read IO in domU
Hi, I think I must''ve done something incorrectly, but I can''t quite figure
out what it is.
To compare disk I/O performance in dom0 and domU, I ran the following two dd
lines and observed vmstat 1 results (for blocks read/written per second),
dd''s reported speed, etc. both dom0 and domU are allocated 512MB of RAM, so
reading the 1GB file should not benefit from

contextstack overflow
Hi all,
I´m an absolute beginner in R programming…I have a really long R-code with
many variables. When I run the program I always get an error at the same
place called “contextstack overflow”. Does anybody know what to do in this
case? Are there so strict limitations in R? If yes, is it possible to handle
it? How?
Thank you for any help!

Ok, Jumbo's enabled on the switch and media server. For the sake of our sanity jumping back and forth, I am trying to enable jumbo's on the bonded pair in the target, # ifconfig bond0 mtu 9014 and it errors
