[dm-devel] Kernel Oops 2.6.10-udm1



Hello,

i tried again whitch Clariion and multipath.
Kernel 2.6.10-udm1
multipath-tools 0.4.2.6

I have one qla2310 FC Controller zoned to SPA and SPB.
I start the multipathd and get the following table

3600601601b121200540b8c1caf4ad911: 0 20971520 multipath 0 1 emc 2 2 round-robin 0 1 1 8:64 1000 round-robin 0 1 1 8:80 1000

What i just tested is :
mount device /mnt
start a long running copy cp -a /usr/* /mnt &
Simulate a dead path by blocking port to SP on my SAN-Switch.
Now i can see that the LUN has trespassed to the remaining SP by dm_emc module.
The copy command keeps running.
And now I enable the Port to the SP again while the copy is still running.
What i can see is lot of errors from Buffer I/O follwed by ReiserFS errors and a Kernel Oops.
From now on the Mountpoint is reported as readonly.


I have placed comments (^####) to the messages file.
