Subject: [PATCH 01/10] drbd: allow ping-timeout of up to 30 seconds
Date: Thu, 13 Oct 2011 12:32:07 +0200 [thread overview]
Message-ID: <1318501936-11689-2-git-send-email-philipp.reisner@linbit.com> (raw)
In-Reply-To: <1318501936-11689-1-git-send-email-philipp.reisner@linbit.com>
From: Lars Ellenberg <lars.ellenberg@linbit.com>
Allow up to 300 centi-seconds to be configured for the "ping timeout".
There may be setups where heavy congestion, huge buffers, and asymmetric
bandwidth limitations may need a "huge" ping-timeout as work-around
for "spurious connection loss" problems.
