Re: [dm-devel] multipath tools - 'fail to get path uid' on LUN 0 whenfailback





Confirmed, increasing the timeout loop (MAX_WAIT_SECONDS) is a successful work-around for the underlying udev issue.

In my situation, the race condition is a delay between udevd creating '/sys/block/sd?/dev' and when it gets around to populating '/sys/block/sd?/device/{vendor, model, rev,}' I haven't gone through the udevd code looking for a static sleep, but it does appear there IS a uniform 5-6 second wait between creation of the initial /sys/block/sd?/dev device and udevd subsequently getting around to populating the '/sys/block/sd?/device/*' files.

I have confirmed that the udev-101 release build resolves the root-cause issue. When replacing the RHEL4.4 udev-039 build, there is no delay, and all files are created (effectively) immediately.

It seems safe enough to increase the WAIT_MAX_SECONDS value to allow for poorly-behaving udevd implementations in the wild, IMO. In time, the upstream-fixed udevd will likely make it less likely this wait loop within the code will be hit (it appears). Even if that occurs, I see it as useful to have the multipathd pause and retry, since it is feasible that a udev user would have udevd trigger functions that may be necessary to access/initialize multipath(or other) devices properly, increasing the time it takes to fully populate the /sys entries for it.


Cheers,

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
