Re: [dm-devel] Problem with ALUA Handler



Thanks Hannes.

Actually I could get it to work after making some changes;
In the function prepare_req(), I replaced

//rq->cmd_flags |= REQ_FAILFAST | REQ_NOMERGE;
	rq->flags |= REQ_FAILFAST | REQ_NOMERGE;

with following:

rq->flags |= REQ_BLOCK_PC | REQ_SPECIAL | REQ_QUIET;

This worked for me.

Thanks for your support.
Regards,
Pradipmaya.
