Description of problem: gnbd and device-mapper-multipath do not work well together. GNBD devices that should not be monitored are being monitored by multipathd, and some gnbd devices that should be monitored are not. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.modprobe gnbd 2.service multipathd start 3.gnbd_import -i <gnbd_server> 4.gnbd_import -R Actual results: all 128 gnbd devices are monitored, even though none are used. When gnbd device is unimported, it is still monitored Expected results: only used gnbd devices are monitored. When then are unimported, they stop being monitored Additional info: There are small fixes necessary for both gnbd and device-mapper-multipath. I already have the code done and tested.
Devel ACK for beta2 - regression from rhel4.

This is fixed. multipathd now only monitors the correct devices, and gnbd correctly informs it when to update
