Hi,
If you had read Documentation/filesystems/ntfs.txt of the new ntfs driver
you would have found a detailed description of how to use the various
software raid types supported by windows on Linux... So you aren't telling
us anything new... But nice to know it worked fine for you, too. (-:
Note that it is no problem to read the set under 2k again. You have
correctly specified not to use persistent super blocks which means that
nothing was written anywhere at all... And you don't even need to run
mkraid. You can just do a simple (as root): raid0run -a
and this will start all devices specified in /etc/raidtab.
Best regards,
Anton
