GlusterFS & XenServer Baremetal
Hello,
What is for you the best GlusterFS scenario in using XenServer (i'm not
talking about Xen on a linux but XenServer baremetal) for a web farm
(Apache-Tomcat) ? I were thinking of using ZFS as the filesystem for the
different nodes.
The objectives/needs :
* A storage cluster with the capacity equal to at least 1 node(assuming all
nodes are the same).
* being able to lose/take down any

Bridge Networking stops working at random times
...ing, the only way I found to fix it is a reboot. This sometimes takes
10 min, other times it may be up for 10 days. This happened with default
xen that comes with RedHat EL 5.2 as well as a default install of Fedora
8.
Any ideas?

Xen - Backend or Frontend or Both?
...Does this make sense? I would think that it would speed up self-heal
operations quite a bit.
Also, is it possible to use both? Could you replicate / distribute on the
server side AND on the client side using the same raw volumes?

Infiniband Drivers under Xen kernel?
Hello folks,
I am running Xen 2.6 under Centos 5.2 installation, and am trying to port
Xen migration abilities to Infiniband. But, the InfiniBand drivers do not
work under Xen kernel, only under non-Xen kernels. It looks like I need to
install some patches to rectify the situation.
Has anyone ever worked with Infiniband and Xen and would be able to give me
inputs about the same? I would really

drifting clock in domUs
Hello,
On a xenserver with several (39) domUs, we experience problems with the
system clock of the domUs. The clock seems to drift away several seconds
up to two minutes from the dom0 clock.
We do have set independent_wallclock=0. According to the docs (i.e.
http://wiki.xensource.com/xenwiki/InstallationNotes) that way domUs
should use the dom0 clock, but apparently that''s not the case.

open file heal
...r
about a week now and I am concerned that when I have a crash I could lose
all the new data.
Is there a way to see what node GlusterFS is using for a open file and is
there a way to force a update to both files while it is open?

Monitoring time drift of hosts
In reading the Xen list there are frequent postings regarding NTP time
drift issues for virtualized guests, correct configurations, etc.
We have a solution (no cost) for monitoring time drift of hosts for
anyone needing to do so or to determine whether their environment is
maintaining time synchronization. For etiquette I am not publishing the
information to the list mailing. If interested,

drbd 8 primary/primary and xen migration on RHEL 5
Greetings.
I''ve reviewed the list archives, particularly the posts from Zakk, on
this subject, and found results similar to his. drbd provides a
block-drbd script, but with full virtualization, at least on RHEL 5,
this does not work; by the time the block script is run, the qemu-dm has
already been started.
Instead I''ve been simply musing the possibility of keeping the drbd

DomU strange network behavior
I am experiencing strange network behavior from several DomU''s. I can ssh
from DomU to any host on the local lan/vlan, I can ping those hosts. However
when I go to resolve a hostname DNS fails. I have verified that three other
DomU''s are exhibiting the same behavior. I have also verified that Dom0 is
functioning properly and can resolve hostnames and access hosts outside of

Xen SAN Questions
Hello Everyone,
I recently had a question that got no responses about GFS+DRBD clusters for Xen VM storage, but after some consideration (and a lot of Googling) I have a couple of new questions.
Basically what we have here are two servers that will each have a RAID-5 array filled up with 5 x 320GB SATA drives, I want to have these as useable file systems on both servers (as they will both be

Exorbitant cost to achieve redundancy??
I'm trying to justify a GlusterFS storage system for my technology
development group and I want to get some clarification on
something that I can't seem to figure out architecture wise...
My storage system will be rather large. Significant fraction of a
petabyte and will require scaling in size for at least one decade.
from what I understand GlusterFS achieves redundancy through

Cluster (VPC), Eucalyptus and preferred distribution to it.
In english:
Buddies,
The Eucalyptus is a system to build a cluster and provide a service such as
Amazon EC2 on its own structure. It is very promising, flexible, stable and
well documented.
The team of Eucalyptus just created an Internet election to choose which
distributions will be officialy supported by it.
I would ask everyone for voting in Debian! Let me explain why.
