>#!/bin/bash

># Test script for Bug 1090446.
>#
># Actions:
># - create a one-brick volume
># - start the volume
># - wait for nfs to be ready and serve the export
># - mount the volume over nfs
># - start a sub-process to create files in a dir on the nfs-mount
># - while files are being created, add a new brick to the volume
>#
># Expected results:
># - after add-brick has finished, the NFS-mount fails to create new files
># - the parent-dir for the new files on the NFS-mount returns ESTALE
>#
># Workaround:
># - when the first copy error happens, run 'rebalance fix-layout'
>#
>
># set FIX_LAYOUT to 0 to disable and cause failure
># any non-0 value will trigger the workaround/fix-layout
>FIX_LAYOUT=0
