Bug#582180: multipath-tools: Cannot resize multipath map online

[Gilles Mocellin]

Package: multipath-tools
Version: 0.4.8-14+lenny2
Severity: wishlist

When you resize a SAN LUN, you have to rescan all block devices with
echo 1 > /sys/block/sdX/rescan

This is not sufficient for the multipath map to be resized.

RedHat/CentOS 5 have added a command to the multipathd command-line mode
(-k) : resize map.

This is really usefull.

Without that, you have to umount filesystems and deactivate the potential volume
group that seats on the multipath device.
