no_path_retry question

no_path_retry question

[Dale.R.Fowle]

Hi all, I have a question on what the retry in the no_path_retry option
refers to. If we use a number like 60, instead of "fail" or "queue", does
Multipath Tools retry an IO at one second intervals? Or is this retry based
off of the SCSI timeout value within the kernel?

Thanks,
Dale

It refers to the number of times that multipath will check for a path before
failing. So it is approximately no_path_retry * polling_interval seconds.
