In multipath/Makefile endif EXEC = multipath DEBUG = 3 all: $(BUILD) Multipathd: path checker startup happens for all devices as previously, however nothing else happens. Log ends here. Waiting for over 1 after one instance of the restart of the multipathd daemon and nothing happen. The following is displayed after the daemon is restarted though: Device Mapper prerequisites not met > > Dec 13 21:12:40 netsrv83 multipathd: 67:64 : readsector0 checker > > reports path is down Dec 13 21:12:40 netsrv83 multipathd: 67:80 : > > readsector0 checker reports path is down > > Dec 13 21:12:40 netsrv83 multipathd: 67:96 : readsector0 > checker reports > > path is down > ... > > > > > Running the command multipath -v 2 doesn't yield any output > and /dev > > had no dm device created. > > > That the heart of the problem. > You should compile the tool with DEBUG=3 and sent the output. Setup DEBUG=3 in multipath/Makefile. Few additional things: The output of multipath -v2 is now: Device mapper prerequisites not met. I have hotplug-2004-09-23 Device-mapper-1.00.19 Multipath-tools-0.4.0 Kernel 2.6.5-7.111.5 (Could this be the problem?) Also do I need to update the multipath.ko modules with a newer version? I noticed it is the still the inbox default that is loaded. Thanks Aboubacar.
