Thank you very much. I apologize, I did reverse the arguments in my email. However, I was using them correctly in a script when I ran the commands. To summarize the problem, after I mount one encrypted (following the OpenBSD FAQ instructions) USB drive, it works fine, until I mount a second encrypted USB drive. At that point I get errors like Feb 18 09:04:14 freda /bsd: softraid0: chunk sd4a already in use Feb 18 09:04:22 freda /bsd: softraid0: sd5: i/o error 0 @ CRYPTO block 27xxx It doesn't happen every time. I switched to new drives but the same thing happened. I will just chalk it up to bad drives or cables for now, and I'll send more complete error records if it happens again.
