Hello all, At our office a have a server running 3 Xen domains. Mail server, etc. I want to make this setup more redundant. There are a few howtos on the combination of Xen, DRBD, and heartbeat. That is probably the best way. Another option I am looking at is a piece of shared storage, a machine running CentOS with a large software RAID 5 array. What is the best means of sharing the storage? I would really like to use a combination of an iSCSI target server, and GFS or OCFS. But the iSCSI target server in the CentOS repos is a 'technology preview' Have any of you used the iSCSI target server in a production environment yet? Is NFS and option? Kind regards, Coert Waagmeester
