typo perform
fragmentation at random position use inplace=1 will allocate and free blocks inside defrag event improve load pressure. This tests are considered dengerous because 300'th and 301'th are known
typo dangerous
I think you meant to set NUM_JOBS here like you did in [Patch 08/10], something like:to trigger OOPS on recent kernels see:https://gist.github.com/dmonakhov/4770294 Signed-off-by: Dmitry Monakhov <dmonakhov@xxxxxxxxxx> --- 299 | 126 +++++++++++++++++++++++++++++++++++++++++++++++ 299.out | 4 ++ 300 | 143 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 300.out | 4 ++ 301 | 153 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 301.out | 4 ++ 302 | 130 ++++++++++++++++++++++++++++++++++++++++++++++++ 302.out | 4 ++ common.defrag | 4 +- group | 6 ++- 10 files changed, 575 insertions(+), 3 deletions(-) create mode 100755 299 create mode 100644 299.out create mode 100755 300 create mode 100644 300.out create mode 100755 301 create mode 100644 301.out create mode 100755 302 create mode 100644 302.out diff --git a/299 b/299 new file mode 100755 index 0000000..4a7a98c --- /dev/null +++ b/299 @@ -0,0 +1,126 @@ +#! /bin/bash +# FSQA Test No. 299 +# +# Ext4 defragmentation stress test +# Defragment file while other task does direct io +#----------------------------------------------------------------------- +# (c) 2013 Dmitry Monakhov +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation. +# +# This program is distributed in the hope that it would be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
