Just wanted to see if anyone has had the opportunity to expand a MetaLUN on an EMC CLARiiON. The O/S is Red Hat AS 2.1 running Oracle 9i RAC (4 node). The filesystems are a series of LUNs combined into a MetaLUN that is formatted and mounted as OCFS. We are ready to expand a MetaLUN, but wanted to see if anyone has done this "on the fly", ie: Expand the MetaLUNs while the systems are still up, then reboot each server one by one and only have a "rolling" outage (instead of shutting all 4 nodes down, expanding the MetaLUN, then bringing each node back up, thus creating a 100% outage). TIA
