I just tried this but I'm having problems getting it to work.. # multipathd -k"resize map mpath-resize-test" fail The underlying SCSI devices have been online resized already, and verified from dmesg and from /proc/partitions to be bigger. I'm running rhel5 kernel with scsi online resize patches (2.6.18-93.el5.bz444964.2) and dm-multipath testing packages with support for online resizing (device-mapper-multipath-0.4.7-19.el5.i386.rpm).
