iotests/081: Test rewrite-corrupted without WRITE
Test what happens when a rewrite-corrupted quorum node performs such a rewrite, while there is no parent that has taken the WRITE permission. Signed-off-by: Max Reitz <mreitz@redhat.com> Message-Id: <20201113211718.261671-4-mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
