Hello,


I'm running kernel 2.6.18 + multipath-tools 0.4.7.

Using Emulex HBA (kernel driver 8.1.9) and DDN S2A8500 disk array, multipathd 
generates a 'fail to get path uid' error when failback from link down failure. 
This only happen for LUN0 of the target. All the other LUNs are nicely detected 
and dm are updated for these other LUNs.

attached is the multipathd log (multipathd -d -v4) and the system syslog.
=> I'm thinking that multipathd can't open the /dev/sdX related to LUN0 as soon 
as the the scsi event is received. multipathd processing is delayed (until open 
error is fired) then the other LUNs are processed (with sd that can be opened).
Following such issue, LUN0 can be put back in multipath configuration by running 
by hand multipath command (but we lose the advantage of the multipathd 
monitoring...)

Did anyone get such issue ? any idea to solve it ?
(may be a way to add a delay between event and scsi_id detection ?)

Thanks for your help.

You're having identical symptoms to what I reported earlier this week, 
with the same versions.  I've since upgraded the base device-mapper 
package to 1.02.11 and recompiled multipath-tools, with no change.

   https://www.redhat.com/archives/dm-devel/2006-October/msg00038.html

Haven't heard any response yet on it, so I'm slowly going through and 
debugging the relevant code and tracking it down. Initially I thought it 
was a race condition due to a udev device-creation delay, but it appears 
the hangup is actually in /sys/block or (/sys/class) somewhere.

It's looking to me like it points to the block device being (improperly) 
flagged as a partition here:


multipathd/main.c:961 (uev_discard):

         if (sscanf(devpath, "/block/%10s", a) != 1 ||
             sscanf(devpath, "/block/%10[^/]/%10s", a, b) == 2) {
                 condlog(4, "discard event on %s", devpath);
                 return 1;
         }


I'm tracking backwards from here, figuring out what vars are passed into 
the function that it is comparing to the device in /sys.

  To: device-mapper development

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

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,


/eli
