I have googled a LOT and even came across this old thread on this list from over a year ago: https://www.redhat.com/archives/linux-lvm/2005-January/msg00080.html My main problem seems to be that I can not find a way to get the OS to see the new size of the LUN, even after rescanning the SCSI bus, running fdisk, doing pvscan, etc. I even tried the suggested blockdev --rereadpt /dev/sdx command but I got a BLKRRPART: Device or resource busy, even tho there is nothing on the device. Does anyone have any clues on how to get Linux (2.6 kernel, SuSE Linux Enterprise Server) to notice that an underlying scsi LUN has changed in size? Thanks in advance, Chris
