Problem:
After spending days getting CCD to work right, I lost a drive.
Now that I have a different drive, the following appears.
ioctl disklabel on ccd0 unable to write.
(BTW the home page for CCD does not load as indicated from Freebsd help
page.)
Now for fun I've done the following:
reformatted the original 2 drives off the scsi controller.
CCD states it made the device:
newfs -f 512 -b 4096 -i 3072 /dev/rccd0c
Warning: Block size restricts cylinders per group to 5.
Warning: 2752 sector(s) in last cylinder unallocated
/dev/rccd0c: 71247168 sectors in 17395 cylinders of 1 tracks, 4096
sectors
34788.7MB in 3479 cyl groups (5 c/g, 10.00MB/g, 3296 i/g)
super-block backups (for fsck -b #) at:
32, 20512, 40992, 61472, 81952, 102432, 122912, 143392, 163872, 184352,
At the end it states ccd can't write disklabel for ccd0c
Now: in the documment of ccd it doesn't state the drives need to be the
same. In fact it references the drives can be different partitions.
If that is the case, would a value of 0 be better than 64?
