How can this happen. It shouldn't. The kernel should check through all of the paths before failing. Sometimes some actions on storage arrays temporarily bring all paths down, but even in that case, you should see messages in the logs of multipath trying all the paths before it fails. > 2. How can I increase the log level to understand multipath decisions. in /etc/multipath.conf defaults { ... verbosity 3 } This will add a lot of extra logging.
