[dm-devel] Multipathd not starting up properly



I'm seeing the following messages when I start multipathd:

Aug 29 19:00:21 multipathd: error calling out /sbin/scsi_id -g -u -s /block/sda
Aug 29 19:00:21 multipathd: error calling out /sbin/scsi_id -g -u -s /block/sdb

Here is the output of multipath -v 3:

I don't seem to be getting anything useful without this call out working.

Any suggestions appreciated.

Adam
