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
