Hi, the dm-mpath multipathing driver enqueues write ios returned by the scsi layer with a "reservation conflict" error (on assymetric storage controllers, like Clariion, where queue_if_no_path is enabled). This is wrong, and a potent data-corrupter : wio sent to a reserved scsi device should never be retried on this same device. Can someone advise on a viable solution for this problem ? I understand the Device Mapper being a block remapper, it is not expected to receive scsi errors directly ... but maybe some kind of translation might be acceptable. Or is there hope in the request-based remapper ? Jens, James, Alasdair, ... as maintainers of the involved subsystems, would you care to give some advise on the issue.
