- can this change affects to all disks in the guest, included node
disk??
Yes, it has affects to all for xen guest defined disks.
Maybe in future we can define storage for xen guests nonshared by default or
shared. This is only if you setup cluster with shared disk on one xen host.
- How can I setup virtual storage in config file, as a normal disk
without any param??
I don't now your question.
Have a look here:

N03300000000000000000
This is my storage config node1 for rhcs with gfs to play and learn about
this. All is done by lvm:
disk = [ 'phy:/dev/xenvg/xenRHEL4_3,ioemu:hda,w',
'phy:/dev/xenvg/xenCLU1fs1,ioemu:hdb,w',
'phy:/dev/xenvg/xenCLU1fs2,ioemu:hdc,w' ]
- If I use GFS and two nodes writing at same time, can this virtual
storage be corrupted??
No, gfs is developed for such scenarios.

Betreff: Re: [Xen-users] Deploying redhat clusters under Xen 3.0.2
Tim, more information:
- I wneed to use GFS filesystem for this virtual storage.
- I do not use heartbeat, I have to deploy this configuration with
RedHat Cluster Suite.
- Only one network interface per node using 100Mb private netowrk.
Thomas,
About this:
If you change in /etc/xen/scripts/block Line 105 and 116 from
echo ‘local’
to:
echo ‘ok’.
I have some questions:
- can this change affects to all disks in the guest, included node
disk??
- How can I setup virtual storage in config file, as a normal disk
without any param??
- If I use GFS and two nodes writing at same time, can this virtual
storage be corrupted??
Many thanks

Hi all,
I need to deploy different RedHat servers with Cluster Suite under
Xen
(using Intel VT hardware for hosts). To accomplish this, I need to
setup
a virtual shared storage disk to serve for several nodes. Can Xen 3.0.2
support disk locking feature to deploy clusters (Load balancing and HA
configs) as vmware products support? Is this feature supported by xen?
And my last question: can I use virtual scsi disk to use as a shared
storage?
Many thanks.
Some more information about your cluster would be helpful :) How many
nics per node, and is one of those nics talking to a private gig-e
network?
We use xen to help manage or completely contain everything from open SSI
to our own pound / lighty / drbd / heartbeat based concoctions and quite
frankly I can't see doing without Xen in the future when it comes to
both ha / load balanced and hpc clusters.
Have you looked at gfs?
Cheers
-Tim
