Can you have a look at this?
I'll get linux-dm.git's 'dm-4.8' branch (v4.8-rc2) loaded on one of my
testbed systems to run the mptest testsuite. It should provide coverage
for simple failover and failback.
I successfully ran mptest against that v4.8-rc2 based kernel. Any
chance you could try mptest to see if it also passes for you? Or if it
is able to trigger the issue for you.
mptest's runtest script defaults to setting up scsi-mq and dm-mq.
Hello Mike,
mptest on top of scsi_debug passes on v4.8-rc3 on the same system I used
to run my SRP tests:
# ./runtest
[ ... ]
PASSED: test_00_no_failure test_01_sdev_offline test_02_sdev_delete
test_03_dm_failpath test_04_dm_switchpg
FAILED:
My SRP tests pass on the same setup if I disable scsi-mq. However, I
still sporadically see I/O errors if I run srp-test 02 on kernel
v4.8-rc3 with scsi-mq and dm-mq:
# srp-test/run_tests -t 02
[ ... ]
