[dm-devel] [QUESTION]: multipath device with wrong path lead to metadata err

[lixiaokeng]

Hi Martin,

    I have tested 0.7.7 and 0.8.5 code.They both have metadate error.
I find I missed some information in last email. Ip1 log in between (1)
and (2) and sdi became a path of 36001405b7679bd96b094bccbf971bc90, but
uevents weren't deal until （3） finished.
    The details described are base on code 0.7.7. I think similar process
exists in 0.8.5 but there may be another to cause error.

The latest "queue" code isn't tested. I will try.

Regards,
Lixiaokeng
