Hi,



In libmultipath/discovery.c, function wait_for_file(char * filename):

- increase WAIT_MAX_SECONDS (from 5 to 10 seconds)
- add a condlog (level 3) to confirm WAIT_MAX_SECONDS and WAIT_LOOP_PER_SECOND 
values, and that we are running the 'daemonized' func.

Doing so, I'm able to get device serial for LUN0 after 6 seconds...
=> udev is always losing the race, and in our case is more than 5 seconds late.
(we are running a dual IA64 server). May be time to upgrade udev (still 039 
shipped in RHEL4U4) ?


Here's the output when serial is OK for LUN0, after a 6 seconds polling on /dev/sdX
