Specify the number of retries until disable queueing, or fail for immediate failure (no queueing), queue for never stop queueing. If unset no queueing is attempted. Default is unset.
Specify any device-mapper features to be used. Syntax is num list where num is the number of features in list. Possible values for the feature list are
queue_if_no_path (Use carefully, see know issues in man page[2] and errata in SUSE https://www.suse.com/support/kb/doc/?id=7022310)
Queue IO if no path is active; identical to the no_path_retry keyword.
Disable automatic partitions generation via kpartx.
