I have made a kernel with ccd support on two of my 2.1.5 systems, and made the ccd devices ccd0 through ccd4 . I would like to concatenate and stripe the disks which hold the newsspool on these servers. I have 4 drives with 2 GB each, and they currently have filesystems on them like /dev/sd1s1e /dev/sd2s1e /dev/sd3s1e /dev/sd4s1e what must I do in order to prepare them for use with ccd ? The manpage speaks about devices named sd2e, sd3e, sd4e, which confuse me a bit. Do I need special disklabels ? Can I use the disks as they are ? I currently use the disks in their entirety for only one filesystem, no DOS partitions on them. Another question I have is, can I use an odd number of disks for striping ? Is it advisable to use ccd if I want to concatenate (stripe) 3, 5 or 6 disks ? Cheers, Michael
