# 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.

|
|
# 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).
