Hi, I looked througth the mail "Barriers still not passing on simple dm devices". It seems that the dm multipath driver could not guarantee the order of I/Os. But as far as I know, other dmp driver such as Veritas dmp driver could handle this. How could other dmp driver handle this since there is some limitation in block layer?
