The problem I observed is that there were two connect attempts (one triggered via udev and one via the test itself) which disturbed the test. The interference resulted into a complete hang of the test case: https://lore.kernel.org/linux-nvme/6g53yj5afhhonwf2psf7ft2gkakkwewy7klkix3y3u6uclpa5w@tt2yfzigyxgg/ > We define unique nqn/ids/etc. So we never should disturb other running > services, unless it uses the same parameters, which shouldn't happen. Yes, that should do the decoupling between udev and blktests. > Agree on setting the hard coded values for hostnqn and hostid instead of > reading the /etc/nvme/* files. This should do the work IMO, isn't it ? Do you mean that nvme-cli will ignore the udev trigger when a different hostnqn is invovled? At least for the well-known discover controller the hostqnq doesn't work. Though not sure if I understood you correctly here.
