Hi, we are messing around with LVM and dynamically increasing SAN disk capacity. We are trying to get to a point where we can increase capacity to the host dynamically on demand without interruption to the host. This is one of the major advantages of a storage area network, we can increase the size of a LUN on the fly, then we just need the host to pick it up. The reiser FS can successfully increase itself over the new volume, we are just trying to get LVM to pickup the new size of the physical volume. Is there a command to re-scan the size of a physical device and update the physical volume under LVM. We can't seem to find one. any suggestions are very appreciated.
