Is there anyone who is running CCD devices successfully?

I have done so, and I know others.

I have just spent 8 hrs loading data from disks to the ccd devices I built and tested. As soon as I got the 15 GB of data loaded, I sync-ed the system and rebooted. Lo and behold the ccd device would not come up. I run fsck on it and it tells me bad super block, values disagree with those in first alternate. I give it an alternate superblock number (32) to fsck from, and tells me bad super block, magic number wrong. I just can't do another newfs on it to find the other super block numbers.

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. I am about to trash it and go with NT.

It's difficult to tell if you don't give any details. What kind of CCD are you building? What version of FreeBSD are you running? 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.
