+# Bug 892730 - Verify that afr handles EIO errors from the brick properly.
+#
+# The associated bug describes a problem where EIO errors returned from the
+# local filesystem of a brick that is part of a replica volume are exposed to
+# the user. This test simulates such failures and verifies that the volume
+# operates as expected.

+# The graph is a two brick replica with error-gen enabled on the second brick
+# and configured to return EIO lookup errors 100% of the time. This simulates
+# a brick with a crashed or shut down local filesystem. Note that the order in
+# which errors occur is a factor in reproducing the original bug (error-gen
+# must be enabled in the second brick for this test to be effective).
