:We didn't go as far as modifying the structure definition, just the
:few "bcount" variables in the ccd.c code.
:The problem was that we were seeing bcount go "negative". I believe that
:"newfs" of the ccd would panic the kernel, reliably. Even on "smaller"
:ccds (1 Gbyte), I believe.
:I'm talking about ccds configured as in:
: ccdconfig -c ccd0 0 0 /dev/da0s1c

:I know, this is fairly worthless as it stands, but it is done so we can
:later "upgrade" the ccd to a mirror.

:RSN, we will be moving to vinum. Hi Greg!

:Linux, BTW, does s/w RAID5. But, it seems you can't operate in degraded
:mode, and the RAID5 reconstruction happens at boot time. We've got a 130
:GB RAID5 volume under Linux that takes about 10 hours to "ckraid". I hope
:that this box never panics!

This is very odd. I use several multi-disk ccd stripes, including one at
BEST across three 18G drives (one 54G partition!). I've never had a
problem.
I believe that at some point in the past 'newfs' and 'fsck' had overflow
problems, but those were fixed.
