Hmm, I'm trying to play with it, and some things are not obvious to
me. I can launch fsstress directly, works well, but as I would
like to run all possible tests, I'm trying the check script, as
explained in the README file.

So I've set the partition and ran the script:

export TEST_DEV=/dev/sda3
./check -r

But:

[: 53: ==: unexpected operator
common.rc: Error: $TEST_DEV (/dev/sda3) is not a MOUNTED xfs filesystem
Filesystem    Type   1K-blocks      Used Available Use% Mounted on
/dev/sda3 reiserfs   134797288   2982296 131814992   3% /data


I'm not sure how I can run these tests on a non-xfs partitions.
I must be missing something.

Thanks.
