I am very happy with RedHat Cluster Suite and GFS2 on a shared SAN storage (i.e. scsi block device), since RedHat Cluster Suite not only handles the file systems but also looks to the availability of the xen vms (live migration, restart, etc.). Dirk Am 14.10.10 13:25, schrieb Rudi Ahlers:

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
