From 59dd0a22ca4c3ac70c37263208b9e49cfeacf2e4 Mon Sep 17 00:00:00 2001 From: Peter Lieven Date: Thu, 16 Apr 2015 16:08:30 +0200 Subject: [PATCH] block/iscsi: increase retry count The idea is that a command is retried in a BUSY condition up a time of approx. 60 seconds before it is failed. This should be far higher than any command timeout in the guest.
