It does not look so good any more. I started bonnie++, it got hung up, i 
tried to shutdown, which hung, so i had to press reset and now the RAID 
controller seems fscked up, it can't initialize anymore. I will consult 
the handbook and try to figure out, if there is a reset jumper or such.

Even before i noticed that the raid is broken (when i saw bonnie++ 
hang), i decided that i have spent enough time trying out Dragonfly.
It's not only time that worries me. I have run into various problems 
with DFly (ATA-Controller not supported, RAID-Controller problems, NFS 
problems, many problems with ports) none of which occured with 
FreeBSD-5.3. And i do not know what problems are still to come.
My impresssion is that DFly is not yet ready for production, at least 
not for our requirements.

So i think i will be better off using FreeBSD.

I really appreciate and thank you all for your help and i hope that the 
project can benefit from my problem reports.


One more question: Will DFly be supporting UFS2 some day? That way i 
could always easily switch without having to backup/restore my data.

Regards,
	Heinrich
