I'm trying to find a kernel fix for this issue. I'll post patches for 2.6.23 kernel. (But it should be easily adaptible to other versions.) I have tested the patches mainly on modified LVM2 (i.e. resizing mirror LV). Since I don't have resizable multipath device, if you are interested in testing, it would be much appreciated. Alternative is to use dmsetup directly, as Aaron suggested. But there is a corner case that if all paths are down before 'dmsetup suspend', I/O errors will occur regardless of queue_if_no_path setting.
