I would guess that you've screwed up the configuration file somewhere along the way. You *are* talking to /dev/ccd? and not the component disks, aren't you? > All you guys that have responded have been a great help, but I just > don't get any confidence in this system. I'm not overly impressed with the resilience of CCD either, if it makes you any happer. But it does work. > I have also, in the last 24 hours, had the system lose the device files > for my /var /usr, and / file systems. Any ideas. No. > What is wrong with this disk system.

What happens if you do a newfs, copy a couple of files to it, and then reboot? > I believe I could have had an NT server up and running in half the time > a 1/10 the frustration of fooling with this ccd system. With CCD? Of course, you'd also get 1/10th the performance, with or without CCD. > Pardon the venting, but I have been working on this system now for > almost 18 hrs today, and I am now at start-over. My sympathies. But you'll get more help if you give a few more details. Greg
