I'm thinking about using the ccd disk driver to set up a striped
and mirrored news spool.  Looking at the code (in 2.1.5), it seems
that the mirroring function only causes writes to be doubled.
Reads all go to the first drive in the set, and there seems to be
no code to read the second drive in case of errors on the first.
Can anyone confirm this for me?  Is anyone using the ccd driver
in a striped/mirrored configuration for a news spool?

Thanks,

Curt Welch
