Re: [Xen-users] Deploying redhat clusters under Xen 3.0.2

[carlopmart <carlopmart@xxxxxxxxx>]

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
