Re: multipath tools - 'fail to get path uid' on LUN 0 whenfailback

Eli Stair <estair@xxxxxxx> · Mon, 16 Oct 2006 15:58:12 -0700

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
