Hi Ingmar- DRBD can be used from within xenserver to replicate storage repositories. This is documented in our extended users guide. You can also use DRBD to build HA iSCSI/NFS clusters to serve HA SRs to an entire xenserver pool. However, HA on the VM level is the job of a higher level cluster manager and, AFIK, this is either not possible to do with OCF-based CRMs or nobody has developed it yet. It is something I plan on looking into in the coming months. Citrix offers an enterprise add-on for this but it does not provide any redundancy on the storage level, so some other form of shared storage (more $$) is required. If you need HA storage repositories for your xenserver domUs, DRBD is a relatively easy "drop in" solution. If you do not need or want the features of XenServer/XenCenter, heartbeat/pacemaker can monitor OSS Xen domUs in addition to DRBD. There is an Xen OCF script that is shipped with Pacemaker. hope that helps Adam Beck Ingmar wrote: > Hi, > > are there news regarding Citrix XenServer 5.5 and drdbd as HA solution? > Florian told me some months ago that so far there is no known solution > for this. > > Has someone already implemented this?
