Hi Jens,

Test srp/002 simulates network failures while running fio on top of dm-mpath.
Since queue_if_no_path is enabled in multipath.conf dm-mpath will keep retrying
the block layer requests it receives if these requests fail due to path removal.
If fio reports "io_u error" for this test then that means that the test failed.
I haven't seen fio reporting any I/O errors for this test with any upstream
kernel that I tested in the past year or so.

Bart.
