Hi, NO_PATH_RETRY_UNDEF is 0 no_path_retry Specify what to do when all paths are down. Possible values are: value > 0 number of retries until disable I/O queueing. fail for immediate failure (no I/O queueing). queue for never stop I/O queueing. Similar to queue_if_no_path. Is there any real difference? Thank you. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
