Testing Linux raid compatibility in ccd:
========================================

Linux side:
-----------

Run
  ./make-test-raids bar
on a Linux machine.  It creates a bunch of files containing parts of
raids with ext2fs in them and leaves md5s in them.

Place raidtest_* in /tmp on the FreeBSD machine.

(I am happy to give you some of these files if you want to test it and
don't have access to a Linux machine)

FreeBSD side:
-------------

Run
  ./mountone all
on the FreeBSD machine.

It will mount the original raids, check the md sum of the files in
there and run fsck on them.

%%

Notes:

These testing scripts will use /mnt/tmp and umount it.  These testing
scripts are not careful to preserve whatever mds/loops and ccds that
you might already have.  However, as long as they are busy your
existing mds/loops and ccds should be fine.

You will need ports/sysutils/e2fsprogs on the FreeBSD side.

The Linux side needs ports/misc/cstream and shellsupport.  I don't
think there's a port yet, it's on

Bugs in ext2fs in FreeBSD may make this fail even when the ccd code is
fine.
