<div dir="ltr">Hello Guys,<div><br></div><div>It's a general question about how dm and particularly multipathd handle IO? I mean, is it a transaction? Is each IO initiated from the OS get back an acknowledgement? If it is, is there a retry mechanism?</div>
<div>Or are the IO sent blindingly to the block device?</div><div><br></div><div>If someone have some good article on it, I would be very interested in understanding more deeply how IO are handled.</div><div><br></div><div>
Thanks a lot,<br clear="all"><div><br></div>-- <br>Nicolas MICHEL
