In setting up multiple cluster servers using a MSA1000 SAN, can I setup one array/LUN on the SAN to contain the SBD partitions for the several clusters? Each set of two cluster servers will use its own array/LUN for the OS+Data. In some of the readings I have seen, the SBD partition will be automatically setup on a drive if there is available disk space. I have tried this and the first works fine on /dev/sdc, then if I create a second cluster and point to /dev/sdc during the creation of the second, the second cluster information overwrites the first. It is not added to the available disk space of /dev/sdc. /dev/sdc is two harddrives mirrored together with a hotspare.

Hope this makes sense.
